39 kinds of flower hydroponic methods ~~

The production process of hydroponic products: Select mother plants - remove the pot and flush the roots - cut the roots or cut the base - disinfect and root treatment - plant in planting cups (ceramsite planting) - root in the root bed - hydroponic bed mutation - harden the seedlings for sale (management during this period is computer-assisted management)

The cultivation process of hydroponic flowers is a very complicated process, which requires a series of processes such as root washing, root pruning, disinfection, planting, root promotion and root induction, and the time required ranges from one to twenty days to half a year.

I have been looking for information about hydroponics on the Internet. Now I have uploaded the relevant information I have collected over the past year, as well as the hydroponics methods of 39 kinds of flowers to the Xinya Flower Shop WeChat public platform, and shared it with everyone~~~ I hope you like it~~~~

1. Umbrella

1. Use the root washing method and the division method to change the formed plants to hydroponics. The old roots are adapted to the hydroponic environment and generally will not rot. New roots will grow in the water in about 7 days. It is suitable for low-concentration nutrient cultivation.

2. The crown of the Umbrella is larger and denser. The number of branches in hydroponic cultivation should not be too many. Too dense branches will affect ventilation and light transmission, and appear messy. Sparser branches will be more natural, and 7 to 9 branches will be enough.

3. To prevent lodging, deep containers should be used for planting.

4. The stomata on the leaves of the parasol tree are well developed and numerous, and the transpiration is vigorous, so the solution consumed naturally needs to be replenished in time. It is a relatively easy plant to grow hydroponically.

2. Spathiphyllum

1. The original root system of the plant formed by hydroponic cultivation by division and root washing can adapt to the hydroponic conditions quickly, and generally no root rot will occur. New roots can sprout in 7 to 10 days, and you can enjoy the flowers, leaves, and roots in a short time! 2. The root system of Spathiphyllum is well-developed and white as jade. It is better to cultivate it in a container with relatively high clarity for better viewing effect.

3. Spathiphyllum prefers shade, and hydroponic plants can also bloom in semi-shade indoors.

4. When soil cultivation is switched to hydroponics in summer, some old leaves will begin to turn yellow. They should be removed in time and the water should be changed every day. After a week, the frequency of water changes should be reduced.

3. Coleus

1. For hydroponics, it is advisable to cut off a 5-8-piece stem from the plant and insert it into water. When the water temperature is between 15 and 28 degrees, it will generally take 10 to 15 days for the roots to sprout and can be planted in a delicate vase. The leaves of coleus are bright and beautiful, making it a good decorative flower. But be careful not to add too much fertilizer during hydroponics to prevent the leaves from turning green!

2. To keep the leaves bright, place them in a brightly lit place. If there is insufficient light, the leaves will become dull and lose their luster.

3. Use pinching to control height, promote branching, prevent inflorescence from forming, and keep the plant full.

4. Lucky Bamboo

1. It is one of the most suitable flowers for hydroponics. It is widely planted in thousands of households. It is planted by water plugging method, which is very easy to root and requires extensive maintenance and management. At a temperature of 18 to 28 degrees, it is in a growing state all year round. 2. The plant is formed by hydroponics by root washing method. You can see that the original soil-planted roots are orange-red, but when hydroponics, the roots are indeed milky white, and the red and white complement each other, which is very beautiful. Lucky bamboo is elegant and refreshing, evergreen all year round, and has the meaning of bamboo reporting peace, wealth and auspiciousness, and is deeply loved by people.

5. Calla Lily

1. It is easiest to cultivate seedlings from plants. In the early stage of hydroponics, pay attention to changing water and washing roots every day. Calla lilies are one of the fastest-rooting flowers in hydroponics. New aquatic roots can be grown in about 7 to 10 days.

2. The juice in the stems and leaves of calla lily is poisonous. Contact with skin will cause itching and redness. It should be rinsed with clean water in time and be careful not to ingest it.

3. Calla lily has unique appearance and beautiful leaves, making it a great embellishment on your desktop!

6. Pothos

1. Pothos is very suitable for hydroponic cultivation. It is easy to obtain ideal cultivated plants by using the water insertion method and the root washing method. Under hydroponic conditions, new roots can sprout in about 15 to 20 days.

2. Place the aerial roots into water. They can also act as nutrient roots and absorb water and nutrients.

3. During the growth period, dilute the hydroponic fertilizer and spray it on the leaves to make the leaves more colorful.

4. The branches and vines of the green radish are soft and flowing, and the leaves are colorful. Small plants can also be planted in wall-mounted containers and allowed to tilt and droop, like a green decorative curtain, fresh and elegant.

7. Tiger tail orchid

1. For hydroponic cultivation of tiger skin orchids at home, it is best to choose golden-edged tiger skin orchids with yellow leaf edges, which have ornamental value. Under the condition of water temperature of 20 degrees, new roots will sprout in about 10-15 days.

2. The root system of Tiger Piranha is sparse and it is not suitable for pruning. Tiger Piranha has beautiful leaves, and its arrow-like leaves are upright and upright. It has a noble temperament and strong adaptability. It can be used for greening decoration in living rooms, study rooms and dark places.

8. Miniature Coconut

1. Choose small and medium-sized plants grown in soil and use the root washing method to change to hydroponics. 2. The root system of miniature coconuts is thin and underdeveloped. New roots sprout slowly in a hydroponic environment, but old roots are strong and not easy to rot. Generally, the root system is not pruned.

9. Bamboo palm

1. For home hydroponics, it is advisable to select small and medium-sized plants and plant them using the root washing method.

2. It is better to plant sparsely rather than densely. Planting 2-3 branches in each dish can show its beautiful and quiet temperament.

3. The roots of the bamboo palm are dense and elastic and can adapt to the hydroponic environment quickly. However, during the hydroponic process, new roots are not easy to sprout, and even new roots may not grow after several months of hydroponic culture. However, this does not hinder its growth.

10. Chlorophytum

1. For hydroponic Chlorophytum, it is best to choose the aerial roots of the plants grown on the runners [creeping stems] for planting, because the aerial roots on the runners are very suitable for the hydroponic environment and the leaves are easy to manage. The roots will sprout after about 5 days of water cultivation.

2. When using the root washing method or division method to hydroponically culture spider plants, the original thick fleshy roots will rot. The water must be changed every day, the root system must be cleaned, and the rotten roots must be removed. New roots will be able to grow from the rhizome in about 25 to 30 days, and the old roots will gradually adapt to the hydroponic environment and will no longer rot. At this time, nutrient solution can be used for cultivation.

3. When growing spider plants in water, it is advisable to choose green-leaf varieties. Silver-thread spider plants are more difficult to operate.

11. Green Emperor

1. When growing with water-insertion method, it is advisable to cut the upper branches of the stems and vines, and insert the aerial roots into the water. New roots will sprout in about 10 to 15 days.

2. For home hydroponic Green Emperor, it is advisable to use small plants and spray water on the surface of the plants frequently to keep the leaves fresh.

3. The stem of the green emperor is thick. Taking advantage of this feature, it can be cultivated upright for better viewing effect. And provide appropriate scattered light source.

Twelve, Haruha

1. For hydroponic spring fern, choose small seedlings and use the root washing method.

2. Spray water on the leaves frequently and wipe off the dust on the leaves with wet wipes to keep the leaves fresh.

3. The unique shape of the leaves of spring feathers makes it an excellent choice for home decoration.

1. Cut off the upper branches of appropriate length, wash off the wound, and plant them in water. It will take about 20 days for the roots to grow in an environment with a water temperature of 25 degrees.

2. Using the root washing method to change the formed soil-grown plants to hydroponics generally does not cause root rot. However, it must be planted with a low-concentration nutrient solution.

3. Using water to cultivate Guangdong Evergreen has a long history. It is quite common in Guangdong to use glass bottles to cultivate water. It is convenient to carry water, clean and hygienic. It has a unique charm.

14. Monstera

1. Monstera is very adaptable to hydroponic cultivation. The soil-planted plants can be converted to hydroponic cultivation by the root washing method all year round.

2. Planting with water. The aerial roots on the branches should be kept intact and inserted into the water. The aerial roots can be transformed into nutrient roots and support the plants.

3. Monstera has large leaves and thick stems. When growing it in water, it is advisable to use thick and stable containers to prevent it from falling over.

4. Use a fine-hole spray bottle to spray water on the leaves to increase the humidity of the environment, which is beneficial to the growth of the plants.

15. Synthetic sweet potato

1. The root washing method can be used to plant shaped plants without seasonal restrictions. The water planting method can be carried out all year round as long as the plants have aerial roots.

2. It is easy to manage and grows fast. It is advisable to renew the plants frequently. Cut off the top branches of the plants that have grown too long and plant them separately. The plants will grow new roots in about 10 days. The axillary buds on the old stems will also grow quickly.

3. For hydroponic Syngonium, it is advisable to choose small plants of White Butterfly Syngonium, Pink Butterfly Syngonium, and Silver Leaf Syngonium with bright leaves, and cultivate them in vertical shapes. Because of their bright leaves and butterfly-like shape, they are quite ornamental.

16. Bromeliad

After flowering, the root buds can be used for hydroponics. The root buds should not be too small when separated. They can be broken off by hand, the base is flattened and several leaves near the base are peeled off, and placed in a container so that it touches the water surface. In a shaded and 20°C environment, it will take root in 2-3 weeks. You can also take potted plants and wash the roots and then hydroponically, but the rooting is slower, about one month and the roots are less. The pH value of the nutrient solution is between pH4-5. The bromeliad is small in size and bright in color, making it a good choice for desk decoration.

17. Coral Begonia

You can cut the branches and insert them into water, and they will take root in about 3 weeks. In the early stage of hydroponic culture, the dilution multiple of the nutrient solution can be appropriately increased (500 times); after new roots grow, use the 200-fold diluted solution for cultivation, and adjust the liquid level to 1/2 of the root system. The coral begonia has a graceful posture, clusters of small flowers, and unusually beautiful leaves. It is an ornamental plant with excellent flowers and leaves.

18. Geranium

Take the branch, dry the cut end, place it in a container, make it touch the water surface, keep it above 20℃, and it will take root in about a month. It can also be potted and water-cultured.

19. Hydroponic tulips

When growing tulips hydroponically, you need to choose the right varieties according to the needs of the flowering period, so as to ensure the tulips are bright and beautiful. The second is to control the temperature. From bulb germination to flowering, it can be divided into three management periods, namely germination period, vegetative growth period, and flowering period.

1. Management during the germination period: Fill the flowerpot with water (ordinary domestic water is fine) to immerse the roots of the bulbs in the water. Place the flowerpot in a sunny place indoors (preferably on the windowsill), keep the room temperature at 13t, and do not change the temperature too much. The roots and buds will grow out in 4-7 days, thus entering the vegetative growth period. Change the water every three days, and change the water once a week after the buds appear. The relationship between the number of days after the bulbs are planted and the number of germinations is as follows:

Days after bulb planting 1 2 3 4 5 6 7

Number of germinations 0 0 0 15 28 39 48

2. Management during the vegetative growth period: During this period, as the growth volume and growth rate of the roots, stems and leaves increase, a large amount of water is needed. The water volume in the pot should be maintained so that the roots are always immersed in water. The growth temperature should be controlled at 15℃-18℃. The temperature should not be too high, otherwise it will grow too long and the stems will be thin and long, affecting the appearance. Since the plant has phototropism, the direction of the flowerpot should be rotated frequently so that the stems can grow upright without tilting. After 2-3 weeks of growth, when the number of leaves reaches 3-4, an elliptical flower camp will appear at the tip of the stem, and it will enter the flowering period.

3. Management during the flowering period: After the buds appear, the temperature can be controlled at 15℃-18℃. After 5-7 days, the buds will gradually open and the flowers will show bright colors. After the flowers open, the flower pots can be moved to a cool place indoors to extend the flowering period. Generally, the flowers can remain open for 2-3 weeks.

Root of Orchidaceae

The ball orchid has a fragrant scent, beautiful color, and a long flowering period, making it a good material for flower arrangement.

The traditional method of growing the ball orchid is to cultivate it in soil. After the test of exposing the roots in water, it has the following characteristics: ① labor saving; ② sanitation; ③ few diseases and insect pests; ④ simple management; ⑤ long flowering period; ⑥ you can enjoy the roots, leaves and flowers, etc.

The method of exposed root hydroponics is:

(-) Seedling treatment: dig up the soil-planted Hoya, wash it with clean water, cut off the dead leaves and leaves infected with diseases and insects, and soak it in diluted flower nutrient solution for half a day.

(2) Potting: Take a glass bottle or vase (without bottom hole), put a few beautiful river stones at the bottom of the bottle, move the processed ball orchid seedlings into the vase and onto the river stones, spread out the roots, add clean water, add flower nutrient solution, and place it indoors or in a cool place.

(3) Management: 1. Spray the leaves with clean water once a day, and after one or two days, spray the leaves with flower nutrient solution once every three to four days: change the water every fifteen days, and add nutrient solution after changing the water; 3. After one month in the pot, inject the head of the ball orchid with flower nutrient solution, half a milliliter each time, and then inject once a month to promote growth, flowering and prolong the flowering period.

(IV) It will bloom in about two to three months after being potted. After the flowers wither, prune the branches, change the water, and inject nutrient solution, and it will bloom again.

Hydroponic method of jasmine

1. Water cutting time: Water cutting can be done all year round. In winter, the container for water cutting can be placed indoors in the sun. In summer, pay attention to shade and prevent scorching sun. The water temperature should be kept at 15℃ to 20℃ during water cutting, so that the cuttings will take root quickly and have a high survival rate.

2. Water-inserted cuttings: Choose branches that are strong and have full buds in the current year. The length of the cuttings is generally 8 cm to 12 cm, and 2 to 4 nodes can be left. Cut about 2 mm below the lowest node, and tie every 10. If there are too many leaves in the upper half of the cuttings, they can be removed appropriately to facilitate rooting.

3. Water insertion container: The container can be a basin with a larger diameter or a wide-mouthed bottle with a shallow bottom, etc. Be sure to wash it clean before use.

4. Water cutting method: Put clean rainwater, river water or tap water in the container to a depth of 8 to 10 cm, then arrange the tied cuttings into the water to a depth of 4 to 6 cm, then put the container outdoors in a ventilated, semi-shaded place. The water must be kept fresh and clean, and the water can be changed every 3 to 5 days. Generally, tumor-like healing tissue can be produced about 20 days after cutting, and fibrous roots can grow in 35 to 40 days.

5. Timely planting: When the fibrous roots grow to 3 cm to 5 cm, they must be planted in time. Be careful during the operation and do not damage the root system. Generally, shade the plant for about 10 days after planting and then normal management can be carried out.

20. Clivia

Clivia can also be hydroponically cultivated, the method is as follows:

Container selection

To hydroponically cultivate Clivia, you must first choose a good container. Generally speaking, a transparent glass container is better. If you want to grow a seedling, you only need a glass canning jar. If you want to hydroponically cultivate a large number of plants, you can use fine iron wire to weave a metal mesh with a hole diameter of one centimeter, and then make a glass hydroponic box slightly smaller than the metal mesh; or you can use a goldfish tank instead. Then cover the metal mesh on the hydroponic box, and insert the Clivia seedlings into the nutrient solution through the mesh. The depth of the flower roots in the culture solution should not exceed the pseudobulb at the root.

Nutrient solution preparation

Nutrient solution is divided into inorganic and organic two kinds.Inorganic nutrient solution can be prepared in the following ratio: 1.5 grams of calcium, 0.01 grams of ferrous sulfate, grams of urea, 1 gram of potassium dihydrogen phosphate, 0.5 grams of magnesium sulfate. After the above 5 minutes of inorganic salts are prepared, it is dissolved in 1000 grams of water and can be used.Organic nutrient solution is prepared as follows: 100 grams of fried sesame seed noodles, 100 grams of bone meal (made from salt-free fresh bones), 150 grams of bean cake powder, 50 grams of cooked sesame powder, and then dissolved in 1000 grams of water.Compared with the above two nutrient solutions, organic fertilizer ingredients are abundant, but the nutritional content is not high, and inorganic fertilizer ingredients are relatively single, but the fertilizer effect is large and quick to take effect.To learn from each other's strengths and make up for their weaknesses, the two can be used in combination.If used alone, inorganic fertilizer is applied once a week, and organic fertilizer is applied once every 5 days.

Water use

When hydroponically cultivating Clivia, you cannot use tap water directly. You must use "trapped" water. The so-called "trapped" water means putting tap water in a container and drying it in the sun for 3-5 days to precipitate chlorides such as bleaching powder that are harmful to the roots of Clivia. From the appearance of "trapped" water, the sediment changes from strips to clumps, and the water color is preferably green. After "trapping" the water, the root position must not be submerged but the pseudobulb. If the water level is too shallow, the Clivia cannot get sufficient water supply, and if the water level is too deep (submerging the pseudobulb), it will cause root rot. During the breeding process, pay attention to observe the changes in water quality. If the roots are found to be yellow or black, it means that there is a lack of oxygen and fertilizer in the water, and the water must be changed immediately.

Air, sunlight, temperature

Whether the ventilation of the roots of hydroponic orchids can be handled well is the key to the success of hydroponic cultivation. After a period of cultivation, a layer of moss will grow on the roots of hydroponic orchids. When the moss is too thick, it will seriously affect the breathing of the roots and corrode the culture solution. At this time, you need to use a soft and clean brush to gently brush off the moss layer (you don’t have to brush it very clean, because a small amount of moss on the roots will not have much impact). In addition, you should always check whether there is enough oxygen in the water. The method of inspection is: put two or three small fish into the hydroponic box. If the small fish swim freely in the water, it means that there is no lack of oxygen in the water. If the small fish always floats to the surface of the water, and its mouth and gills are exposed to the water to breathe, it means that there is a lack of oxygen in the water. After finding that there is a lack of oxygen in the water, oxygen must be supplemented. There are two ways: one is to change the water, and the other is to use a small oxygen pump to supply oxygen to the water. In terms of sunlight treatment, Clivia is a semi-shady plant. Pay attention to light, especially in summer, avoid direct strong sunlight and let it receive scattered light. In addition, according to the phototropism of Clivia leaves, it is necessary to ensure that the leaves receive light evenly, otherwise the length of the leaves will be different and the growth direction will be staggered. Generally, the light angle should be adjusted every two or three days. In terms of temperature treatment, the environmental temperature of mature Clivia should be 11℃-25℃, and the temperature of seedlings can be slightly higher, 20℃-35℃. When growing orchids in water, the temperature difference between day and night should be controlled. In winter, it is better to keep it around 20℃ during the day and not lower than 15℃ at night.

21. Rose

After the roses fade, cut off the remaining flowers and let the branches grow for several days. When the first axillary buds on the branches grow stronger and accumulate nutrients, cut three-node cuttings, remove the petioles at the bottom, and use a sharp blade to cut the bottom buds into an inclined surface. Immediately insert the cuttings into a prepared bottle filled with clean water. The cuttings can be inserted into the water 1/3. To reduce the evaporation of water from the leaves, some leaves can be cut off. In the case of light protection, new roots are easy to grow from the incision, so brown bottles should be used. If brown is not available, a layer of black plastic film can be wrapped around the bottle. The cuttings should be placed on a south-facing windowsill and not exposed to direct sunlight.

When the temperature is high, you can change the water once a week. When the temperature is 15-25℃, it only takes about 20 days for the roots to grow. When the young roots grow to 1-2 cm long, they can be transplanted into pots. Because the young roots grow in water, in order to adapt to the environment, water them once a day at the beginning of transplanting, and then gradually reduce the amount. After shading for a week, it can be exposed to sunlight in the morning and evening, and it will survive.

The advantages of water cutting are: simple method, high survival rate, no time limit, and can be cut after the flowers fade.

22. Azalea

The characteristic of soilless cultivation is to replace soil with artificial substrate. Hunan Forestry Institute uses solid substrate to cultivate azalea without soil and obtains very satisfactory results. The variety is summer azalea. The crown structure of soilless cultivation is compact, the amount of flowers is large, the flower diameter is large, and there are few diseases and insect pests. It not only improves the quality of flowers, but also greatly reduces the heavy physical labor. It is a cultivation method worthy of promotion.

1. Preparation of Matrix

The roots of azalea are very delicate, so a loose substrate is required to facilitate ventilation and drainage. Use 1 part of vermiculite, 1 part of pearl sand, 1 part of river sand, and 1 part of coal slag to mix in proportion. After mixing, sterilize the substrate with 0.1% carbendazim solution, mix it evenly into the substrate, and cover it with plastic film for 1 day. Then rinse it with clean water several times, dry it, mix it with 0.4% agricultural compound fertilizer solution, cover it with plastic film for one month, and then it can be potted for use.

2. Preparation of nutrient solution

Rhododendron has strict requirements on fertilizer. During the growth period, thin fertilizer should be applied frequently. According to experiments, agricultural compound fertilizer is mainly used, supplemented with trace elements, the pH value is controlled at about 5, and low-concentration foliar fertilizer is sprayed, which can achieve good results.

Preparation of macroelements: Add 2 grams of agricultural compound fertilizer and 0.5 grams of magnesium sulfate to 1 liter of water to form a standard solution.

Preparation of trace elements: add 20g disodium ethylenediaminetetraacetic acid, 15g ferrous sulfate, 4g manganese sulfate, 6g boric acid, 0.2g zinc sulfate, 0.1g copper sulfate, and 0.2g ammonium molybdate to 1 liter of water as the mother solution. When using, add 1ml of trace element mother solution to 1 liter of standard solution to obtain the full amount of elements. Preparation of foliar fertilizer: add 1g urea, 1g potassium dihydrogen phosphate, 0.02g boric acid, and 0.1g V.B1 to 1 liter of water.

3. Water and fertilizer management

Since the substrate has good drainage and air permeability, but poor water retention, the amount of watering is generally more than soil culture, just to keep the substrate moist; at this time, the buds and leaf buds are germinating, and the fertilizer requirement is relatively large. Water the plant with a full amount of nutrient solution about once every 10 days. From March until the buds burst, spray foliar fertilizer about 15 days. After flowering, the water requirement is large. In addition to watering every day, the leaves should be sprayed in the evening. At this time, the fertilizer requirement is also large. It can be changed to watering the nutrient solution once a week and spraying foliar fertilizer once to promote the growth of new branches and facilitate the differentiation of flower buds. After entering the dog days, pay attention to keeping the substrate moist and spray water on the leaves. The amount of fertilizer can be reduced to watering the nutrient solution about once every 20 days. After the cool autumn, the amount of fertilizer can be gradually increased. Apply a full amount of nutrient solution about half a month, and spray foliar fertilizer 1-2 times to promote the healthy growth of flower buds. After winter, the physiological activity of azalea is weak, and it is not suitable to fertilize. It can be watered appropriately depending on the dryness and wetness of the substrate. During the cultivation process, there was basically no disease or insect pest.

23. Hyacinth hydroponics

Hyacinthus is a plant of the lily family and a bulbous flower. It has full inflorescences of various colors and white roots.

Hydroponics points:

(1) Choose a container with a mouth that can hold the bulb. It is best to choose a gourd-shaped container that is small at the top and large at the bottom. Transparent glass is preferred. Some daily utensils such as high-foot wine glasses and wine bottles can be used. You can also choose a large-mouthed container.

(2) The water temperature should not be too high, preferably below 15°C.

(3) Place the bulb on the bottleneck. After the roots grow, lower the water level until the roots just touch the water surface. This will allow the roots to fully absorb oxygen and promote root growth. When the roots develop, cover the culture container with black cloth to allow the bulb to develop further.

(4) In winter, move the container to a sunny location to encourage the plant to grow larger and stronger flowers.

(5) You can also plant several hyacinths in the fish tank, using sand as the substrate and some shade-loving ferns as the supplement, to create a small landscape with a wild appeal that is also very unique.

24. Gerbera

A perennial herbaceous plant of the Asteraceae family, with large flower diameters, rich flower colors, and blooming all year round. It likes a warm, sunny, and well-ventilated environment. It is a semi-cold-resistant flower and prefers fertile and loose soil. Gerbera is a good cut flower variety. It can be grown in water for a long time, has high ornamental value, and is also a good absorber of formaldehyde.

Generally, these plants do not require special management when grown in water. Any container with a certain volume for the roots to expand can be used, and glass containers with open mouths are more conducive to maintaining water quality and root growth. When planting, avoid immersing the leaves in water to prevent rotting; place them under suitable light conditions and they will soon take root; add some water when you find that there is less water to prevent the roots from drying out; when the water becomes turbid, take out the plants, clean the container, and refill it with water. Generally, for plants grown in water, change the water every three days and apply nutrient solution once. The ratio and amount of nutrient solution depend on the size of the plant.

25. Asparagus fern

Other names: Cloud bamboo, plane grass

Family: Liliaceae, Asparagus

Morphological characteristics: Asparagus fern has an elegant plant shape, slender and beautiful leaf-like branches, shaped like clouds, like bamboo but not bamboo, with a graceful and free-spirited posture, and white fleshy aquatic roots. When paired with a transparent container, it is both dignified and beautiful, and looks noble and elegant. It is a good choice for hydroponics.

Growth habits: like warm, humid and semi-humid environment, the suitable temperature is 15-25 degrees Celsius, the minimum temperature of the motive is not less than 5 degrees Celsius, likes scattered light, avoids strong direct light, avoids dry air.

Hydroponics tips:

1) Materials: Select soil-grown plants with good plant shape and vigorous growth, wash off the soil and cut off the rotten roots, then plant them in a hydroponic container and add water to one-third to one-half of the root system.

2) Maintenance: Change the water every 2-3 days at the beginning, remove the rotten roots in time, and after two weeks, the root system has basically adapted to the environment and has grown aquatic roots. After that, change the water every 5-6 days. When the plant shows strong growth potential, use nutrient solution for cultivation. The nutrient solution should be shallow rather than deep. Replenish it every 10 days in summer. When the sediment of the nutrient industry increases, renew the nutrient solution. Generally, it is renewed every 1-2 months. Avoid direct sunlight in summer, and place the plant in a warm place with strong light.

Keep the room temperature above 5 degrees Celsius, and spray water on the leaves when the air is dry to maintain high air humidity and clean branches and leaves.

Twenty-six' Ivy (Hedera hellx)

Other name: Ivy

Family: Araliaceae. Hedera

Because of its dense branches and leaves, it is the most ideal material for vertical greening of indoor and outdoor walls. It is also an excellent ground cover plant. It is suitable for climbing buildings, walls, steep slopes, rock walls and the ground under the shade of trees. The demand for potted plants is increasing.

1. Morphological characteristics and varieties

Evergreen climbing vine, with thin and soft branches and aerial roots. The vines grow spirally and can climb on other objects. Leaves are alternate, leathery, dark green, with long petioles. The leaves on the nutrient branches are triangular-ovate, entire or 3-lobed, and the leaves on the flower branches are ovate to rhombus-shaped. Racemose inflorescence, spherical flowers, light yellow. Drupes are spherical and black.

Commonly cultivated species in the same genus include Chinese ivy (H. nepalensis var. sinensis), Japanese ivy (CV. conglomerata), colorful ivy (CV. discolor), golden heart ivy (CV. goldheart), silver edge ivy (CV. siluer quetn), etc.

2. Ecological habits

Ivy is a typical shade-bearing vine plant. It can also grow in a full-light environment and grows well in warm and humid climates. It is not cold-resistant. It is not strict with soil, prefers moist, loose, fertile soil, and is not salt-alkali resistant.

(III) Reproduction methods

The nodes of ivy can naturally take root in humid air, and will naturally enter the soil after touching the ground, so it is mostly propagated by cuttings, using nutrient branches as cuttings. After cutting, it needs to be shaded in time, the air humidity should be high, and the bed soil should not be too wet. It will take about 20 days to take root.

(IV) Cultivation techniques

Ivy cultivation and management are simple and extensive, but it needs to be planted in moist soil and well-ventilated places. Transplantation can be carried out in early autumn or late spring, and it needs to be pruned after planting to promote branching. In the south, it is often planted in the shade of gardens, allowing it to naturally creep on the ground or on rockery. In the north, it is mostly potted. Potted plants can be tied with various brackets and pulled to shape. In summer, they are maintained under the shade shed and watered less, otherwise stem rot is likely to occur. If this disease occurs, the diseased plants should be separated from the healthy ones, and carbendazim and methyl tobuzin should be sprayed alternately. In winter, they should be placed in a greenhouse for wintering. The indoor air humidity should be maintained and not too dry, but the pot soil should not be too wet. Ivy can be grown hydroponically as a whole plant or by cuttings. It is best to do this in spring and autumn. After the roots grow in the cutting bed, the plant can be placed in a planting basket for root induction. Once cultivated, the ivy is very easy to maintain and is clean and hygienic. It is a good choice for home viewing. The cultivated plant can be treated with the general nutrient solution on the market or the nutrient solution for foliage plants. The concentration of the nutrient solution is generally 1/4 of the original formula.

(IV) Other effects

Ivy is not only a good greening plant, but the whole plant can also be used as medicine, which has the effects of dispelling wind, promoting dampness, promoting blood circulation and reducing swelling. It is mainly used to treat rheumatic joint pain, back pain and trauma. Mashing it to extract juice or adding water to boil and wash the affected area can treat sores, swelling, measles and eczema.

27. Qilin

The Euphorbia pulex is usually propagated by cuttings. From April to early September, healthy branches are cut for cuttings. White latex will flow out of the wound of the newly cut stem segment. You can dip it in plant ash or charcoal powder to prevent the flow of latex, and then leave it in a dry and cool place for 3 to 4 days. Cuttings are done after the cut shrinks. Euphorbia pulex has no close relationship with aquatic plants. When hydroponically cultivated, the principle of pollution-free cultivation must be strictly followed, and new nutrient solution must be replaced regularly to increase dissolved oxygen. The temperature in winter should not be too low, otherwise the leaves will fall. The concentration of the nutrient solution should not be too high, and it should not be overly shaded, otherwise it will cause reversion, and Euphorbia pulex will grow the columnar fleshy stems of the original Euphorbia pulex, affecting the ornamental effect; in severe cases, it will cause root rot and death. The white floating juice of Euphorbiaceae plants is poisonous. Especially it should not enter the eyes, and be careful not to let children accidentally enter the mouth or eyes.

28. Brazilian wood

The Brazilian wood has a strong adaptability to light. In the north, it can be placed in a dark room for more than a month, and in a bright room for a long time for viewing. It likes high temperature, high humidity and well-ventilated environment. It is more light-loving and shade-tolerant, but afraid of the scorching sun, avoids dryness and drought, and likes loose, well-drained sandy soil. The suitable temperature for growth is 20℃ to 28℃. In winter, it is necessary to prevent cold damage below 13℃ to prevent the leaves from drying up. The wintering temperature is 5℃. Brazilian wood is mostly propagated by cuttings. April to June is the best season in the north. Large columnar Brazilian wood, the perennial stem itself contains nutrients and water, and the hidden buds on the stem have a strong regeneration ability. Due to the need for decoration, it can be sawed into stem segments of different lengths for planting, but the end of the stem segment should be sealed with paraffin to prevent water loss or infection, which is particularly important in the dry season in the north. Or choose a mature and strong stem (not lignified), cut off the top of the stem with leaves, cut the upper leaves in half, peel off the lower leaves, expose the stem nodes, each section is about 10 cm to 20 cm, and cut into coarse sand, fine sawdust or humus soil 3 cm to 4 cm. The cutting bed is placed in a semi-shaded environment, maintain high humidity, receive 50% to 60% sunshine, and the temperature is 25℃ to 30℃. It will take about 20 to 30 days to take root and sprout, and then be potted. When the stem segment is used as cuttings, rooting is slow, and sometimes it takes 2 to 3 months to sprout and root. It can also be propagated by water cutting and high pressure, but it must be carried out under conditions above 25℃. Water cutting propagation, that is, immerse 1/3 of the stem cuttings in water, change the water every 3 to 5 days, and add a small amount of carbendazim aqueous solution for antiseptic disinfection, which can promote rapid rooting and sprouting.

29. Agave

Common varieties of agave include: gold-edged agave, golden-heart agave, silver-edged agave, green-edged agave and narrow-leaved agave.

It is strong, likes sunshine, and cannot tolerate shade. It is slightly cold-resistant and can be cultivated in the open field at temperatures above 5°C. The leaves of adult agaves are only slightly frozen at a low temperature of -5°C. The aboveground parts are frozen and rotted at -13°C, but the underground stems do not die. They can sprout and grow leaves the following year and grow normally. It is drought-resistant. It likes well-drained, fertile and moist sandy soil. It usually takes decades for it to bloom in its place of origin, and the mother plant dies after flowering. It does not bloom in Nanjing. It can only bear fruit through cross-pollination.

Agave can be grown hydroponically all year round in a heated environment. When growing hydroponically, all its roots need to be removed, disinfected with disinfectant, and then soaked in rooting liquid for a certain period of time. During the hydroponics period, attention should be paid to the cabbage loopers that eat its leaves and hearts, thus losing its commercial and ornamental value. If insects are found, they can be captured manually or killed with pesticides.

For hydroponic root viewing, always take it to a sunny place. Do not place it in a dark place for a long time, otherwise the leaves will turn white and become thin, thus losing their ornamental value. Pay attention to heat preservation in winter. Place it in a sunny place near the window during the day. At night, the glass bottle needs to be placed in a plastic or cardboard box in a room without heating. If the leaves turn yellow or droop down and look listless, it may be frostbite. At this time, you need to take some heat preservation measures. Then place it away from doors and windows. Remember not to place it in the north. When changing water in winter, you can use warm water of 12 to 18 degrees. Agave has strong resistance and can safely survive the winter as long as you pay attention to management.

30. Fortune Tree

The money tree has a graceful posture, majestic crown and emerald green leaves. It looks elegant and attractive when placed in the family living room.

The money tree is a perennial evergreen shrub native to the Malay Peninsula and the South Pacific Islands. In recent years, it has been widely cultivated and bred in urban and rural households. For home cultivation, the following four points should be paid attention to based on its habit of liking high temperature and humidity and being intolerant to frost, cold and dryness:

First, pay attention to the sunlight. The fortune tree likes high temperature, humidity and sunlight, and cannot be shaded for a long time. Therefore, it should be placed in a sunny place indoors during maintenance and management. When placed, the leaves must face the sunlight. Otherwise, the entire branches and leaves will be twisted due to the leaves tending to the light. In addition, spray water on the leaves once every 3 to 5 days with a watering can, which is conducive to photosynthesis and makes the branches and leaves more beautiful.

31. Vinca roseus

Hydroponic method of Vinca roseus

Catharanthus genus of the Apocynaceae family, also known as five-petal plum.

Biological characteristics: Catharanthus roseus is native to eastern Africa. It prefers a warm, slightly dry and sunny environment. The suitable growth temperature is 18-24℃ from March to July, 13-18℃ from September to March of the following year, and the winter temperature is not lower than 10℃.

Catharanthus roseus is afraid of waterlogging. Do not water the pot soil too much, as excessive moisture will affect its growth and development. Especially for plants that spend the winter indoors, watering should be strictly controlled. It is better to keep it dry, otherwise it is very easy to freeze. For open-field cultivation, pay attention to timely drainage during summer showers to avoid waterlogging and the death of the entire plant.

Catharanthus roseus is a light-loving plant that must have sufficient sunlight during its growth period. Its leaves are green and shiny, and its flowers are brightly colored. If it grows in the shade for a long time, its leaves will turn yellow and fall off.

It prefers fertile and well-drained soil, tolerates barren soil, but avoids alkaline soil. Hardened, poorly aerated clay soil will result in poor plant growth, yellow leaves, and no flowering.

Reproduction method: Commonly used methods are sowing, cuttings and propagation.

Cultivation and management: When the seedlings have 3 pairs of true leaves, transplant them to 10 cm pots, 3 plants per pot. Pinch the tops of the seedlings once when they are 7-8 cm tall, and pinch them twice afterwards to promote more germination and branching, and more flowering. Fertilize once every half month during the growing season, or use 15-15-30 "Huiyou" potted flower fertilizer. Plant in pots or flower beds without pots, and bloom from late May to early November, for more than 5 months. Remove the remaining flowers at any time during the flowering period to prevent the remaining flowers from getting moldy and affecting the growth and ornamental value of the plants. August to October is the seed collection period for Catharanthus roseus, and the seeds should be collected as they mature to avoid losing the seeds.

Pest and disease control: leaf rot, rust and root wart nematodes are common. For leaf rot, spray with 500 times diluted 65% mancozeb wettable powder. For rust, spray with 2000 times diluted 50% carboxin wettable powder. For root wart nematodes, spray with 50 times diluted 80% dibromochloropropane emulsifiable concentrate.

32. Auspicious Grass

Hydroponic method of lucky grass

Lucky grass, also known as Guanyin grass, is a perennial green herbaceous plant of the genus Lucky grass in the Liliaceae family. The leaves are clustered, broad and linear, with a concave midrib and a gradually pointed tail, 15 to 40 cm long; the stems are creeping roots, with roots at the node ends; the flowering period is from September to October, the flowers are lavender, upright, with terminal spikes, about 6 cm long; the fruit is bright red and spherical; it is native to the southwest region, likes warm and humid environments, is relatively cold-resistant and shade-tolerant, has low requirements for soil, and has strong adaptability. Because the lucky grass has a beautiful plant shape and verdant leaves, if we take advantage of its cold-resistant and shade-tolerant growth habits, put it into various goldfish tanks or other glass containers for water cultivation, and then put it on the bar counter or coffee table, there will be water in the tank, stones in the water, and roots in the stones, which are clean and visible, and it is a delicate and elegant work of art. The following is an introduction to its cultivation method.

1. Material selection. Select plants with dark green leaves, vigorous growth, and no pests and diseases, carefully dig them out of the soil with a shovel, and clean their roots. In the process of digging, pay attention to digging as deep as possible and taking as much soil as possible. There are two purposes for doing this. One is to avoid damaging the roots, which is conducive to the growth of hydroponic cultivation; the other is that because water is transparent, intact roots can show a unique beauty in the water.

2. Pressing stones. Select pebbles or rain flower stones used to pave garden paths, wash them clean, and first lay a layer on the bottom of the glass jar, place the lucky grass upright on the stones, and then use stones to press its roots firmly to prevent it from falling over, and inject clean water into the glass until the entire root is completely immersed. The transparency of water determines that the pressing stone should also have certain aesthetic skills. The author can use his own creativity to design it to highlight the individuality. 3. Management. Since the roots of the lucky grass are soaked in water for a long time, the water is prone to produce odor over time, so the water should be changed frequently, preferably once a week. In terms of fertilization, a few drops of nutrient solution or potassium dihydrogen phosphate solution can be applied regularly. The lucky grass is relatively shade-tolerant, and 1 to 2 hours of fluorescent light exposure every night can meet its photosynthesis needs.

33. Cyclamen

Cyclamen hydroponic method

Choose cyclamen and containers Choose cyclamen plants that are 1 to 3 years old, free of pests and diseases, growing vigorously, and about to bloom. It is best to use soilless culture media such as perlite, vermiculite, sawdust, etc. to cultivate them. After changing the environment, the roots will not be damaged, the seedlings will not slow down, and they will adapt quickly. Water-growing containers are simple and economical. They can be used to recycle waste in life. Any container that can hold water, such as fish tanks, tea cups, beverage boxes, wine bottles, and vases, can be used; transparent containers are best, and the roots, stems, leaves, flowers, and fruits can all be fully appreciated. No matter what container is used, its size, height, color, etc. must be coordinated with the cyclamen plant, so that the water-grown cyclamen can show its exquisite, crystal-clear and elegant charm.

Cyclamen flowering period is generally from October to June of the following year, so the water-raising period is generally from September to April of the following year. Remove the selected cyclamen plants from the pots and wash the substrate to which the roots adhere with 20°C warm water, being careful not to damage the roots. Then place them directly in a container prepared in advance, with the water depth flush with the root zone, and the maximum depth should not exceed 1/3 of the bulb to prevent the bulb from rotting. Finally, place them in a suitable location indoors, add water and nutrient solution regularly. After two to three months of water-raising, when the flowers fade, take the plants out and plant them in the cultivation substrate to spend the summer.

Water quality and water temperature The best water for growing cyclamen in water is spring water or magnetized water. The water is clean, not turbid, and does not precipitate. It also contains a variety of trace elements necessary for plants. There is no need to change the water during the entire water-growing period. Tap water contains chlorine, which is not good for the growth of flowers, and is prone to turbidity and precipitation. The water needs to be changed every few days and should be avoided as much as possible. The water temperature should be close to the indoor temperature at the time, generally 10℃ to 20℃.

; Light and indoor temperature Cyclamen likes a sunny environment. The water-growing container should be placed on a sunny table or windowsill indoors, not directly on the radiator. The most suitable indoor temperature is 15℃ to 20℃, the highest should not exceed 25℃, and the lowest should not be lower than 10℃. Add nutrient solution Cyclamen should also be regularly supplemented with nutrients during the flowering period. Generally, 50 ml of 1:100 nutrient solution for flowering plants is added to each plant every 10 days. Mountain spring water should also be used to prepare the nutrient solution. If you find yellow leaves, small leaves, small flowers, etc., you can add more nutrient solution as appropriate, excluding root rot.

Thirty-four, Silver Edge Grass

Hydroponic silvergrass

Chinese name: Libang grass

Other name: Silver-edge grass

Family name: Poaceae

Scientific name: Arrhenatherum elatius

Characteristics: Perennial herb

Plant height : 50-100 cm

Flowering period: Summer (June-August)

Cold resistance : cold resistant (- 5℃ or above)

Negative tolerance: positive

Morphological characteristics: underground stems are white and bead-shaped; aboveground stems are clustered and smooth. Leaves are clustered, linear-lanceolate, 750px long, about 25px wide, with yellow-white edges. Panicles have long stalks, about 1250px, and are branched; spikelets have two flowers, the upper flowers are bisexual or female, and the lower flowers are male; flowering period is June-July. Native to Europe.

Habits: Extremely strong, cold-resistant and drought-resistant, and not picky about soil. In midsummer, the above-ground parts often wither and go dormant, and sprout again in early September.

Reproduction and cultivation: Usually, division is carried out every 2-3 years, in spring from March to April or in September when new leaves are first sprouted after dormancy. The old plants are dug up and separated. Each plant should have 2-3 new buds and bead-shaped underground stems. Old plants should be pruned every year to prevent the leaves from growing too long. When the underground stems are exposed, soil should be added in time to make the plants vigorous and beautiful. If too much fertilizer is applied or there is a lack of fertilizer during cultivation, the white spots on the leaves will disappear and the leaves will turn green, affecting the ornamental effect.

35. Hydroponic methods of red and pink anthuriums

Anthurium is a plant of the Araceae family and is also a relatively hydrophilic plant. However, it is a little difficult to grow hydroponically.

When Anthurium is cultivated in water, half of the root system should be exposed to the air so that the root system can breathe in the air (as shown in the picture). Otherwise, it is very easy to cause root rot. The root system of hydroponic plants is exposed to the light. Plant cells have photosynthesis after exposure to light, and the same is true for the roots. It is normal to be green. As long as it is not exposed to direct sunlight, it can usually ensure the healthy growth of the roots. Not all hydroponic plants will eventually turn green and be healthy. For example, some are brown.

Some of the secondary fibrous roots of the pink palm (pink champion) are brown, which is abnormal. Roots of this color should be soft to the touch. This is root rot, which should be cleaned up in time, and the frequency of water changes should be increased to control its spread.

It is a common misconception that plants can survive if they are put into water. Due to their strong hydrophilicity, they can still survive for several months even if put into water.

The roots of anthurium breathe very strongly, and it is easy to hinder its breathing by directly putting it into water. The best way is to use a substrate, and the best substrate is ceramsite. Since the roots of anthurium are fleshy roots, the leaves are pulled out from the roots. Generally, the custom orchid + stone + easy method is used, and it is not easy to produce small leaves. Ceramsite is light in texture and has enough space, making it easy for small leaves to be pulled out. The anthurium hydroponically cultivated in my office is cultivated with ceramsite. I have been raising it for 2 years, and each plant has 3-4 flowers.

To grow anthuriums in ceramsite hydroponics, first clean the roots, trim old roots, residual roots, and remove flowers. Then put the plant into the container. Fill it with ceramsite, then dilute the rooting powder in proportion, spray the ceramsite, and be careful not to accumulate too much water underneath. If there is too much water, pour it out. After a long wait, you will be surprised to find that the thick white fleshy roots of the anthurium grow on all sides, all close to the edge of the container. At this point, congratulations, a hydroponic anthurium is complete. The next thing to do is to add nutrient solution regularly to protect its growth.

Additional questions:

1. Anthuriums that have just been grown in expanded clay hydroponics are not easily exposed to direct sunlight, so just place them in the shade.

2. When you first start hydroponics, don't add nutrient liquid. It's best to add rooting powder. If you can't buy rooting powder, leave me a message and I will teach you how to make your own rooting powder. The effect of using B12 is not very obvious.

3. The container for growing anthurium should be slightly larger. It is best to be wide at the top and narrow at the bottom, in a V shape, and also have a certain height.

4. How long can Anthurium survive when grown in water? It can survive for a long time when grown in expanded clay water. I have been raising it for 2 years and it is producing leaves and flowers every year. I estimate it can survive for a long time.

5. If you want to hydroponically cultivate Anthurium, it is recommended to use ceramsite to induce it and then switch to pure hydroponics. It is not recommended to put it directly into water.

36. Hydroponic method of Schefflera chinensis~~~~~

Schefflera has emerald green and shiny leaves, beautiful plant shape and high ornamental value. Because of its strong shade tolerance, it is an ideal indoor foliage plant. Schefflera is usually potted with culture soil. After testing, it can also be cultivated in glass bottles with water indoors, which can also achieve good results. There are two hydroponic methods:

1. Water cutting propagation , select cuttings:

Cut off the semi-lignified leaf base segment with 2-3 or more nodes from the old plant, about 10 cm long, cut off the lower leaves, leaving only 1-2 palmate compound leaves on the upper part, immerse the lower 2/3 in a glass container filled with clean water, place it in a bright place indoors, and keep the temperature above 15°C. Usually, white callus tissue begins to form at the lower lenticel and base cut of the base segment immersed in water for about 10 days, and soon differentiates into adventitious roots from these places. After about 45 days, the base segment inserted in water will grow roots of more than 6 cm and white root hairs, and normal management can be carried out at this time.

2. Change soil cultivation to hydroponics

Carefully remove the soil-planted Schefflera and clean the soil at the roots, plant it in a transparent glass bottle with clean water (tap water needs to be stored for 2-3 days), change the water in the bottle every 2-3 days, keep the temperature above 15°C, and with proper light, you can grow a plant with green leaves on the outside and ornamental white roots in the bottle. It is elegant, clean, hygienic and very attractive.

Maintenance tips for hydroponic Schefflera:

1. Nutrient solution: Change the water every 7 days. Add hydroponic plant nutrient solution when changing the water. The water level should not be too high and should not soak into the plant trunk.

2. Light: It likes sufficient light and bright leaves. It is also shade-tolerant and has dark green leaves. It has strong adaptability to light, but avoids excessive exposure in summer.

3. Temperature: The optimum growth temperature is 15-25°C, and it can also grow above 30°C. The wintering temperature should not be lower than 5°C, otherwise the leaves will fall off.

4. Maintenance: It grows fast, so pay attention to shaping and pruning.

37. Hydroponics of Dracaena

The hydroponic plants of Dracaena can be obtained by referring to the above propagation method, or they can be obtained directly from soil culture. The specific method is as follows:

For root-observing hydroponics, sterilize and kill insects one week before cultivation, and select plants with good appearance for cultivation. If hydroponics is carried out according to the above cuttings (remove the roots of soil-based materials for rapid propagation and rooting), it is best to put the planting basket in it first, and put it into the mutagenesis tank for mutagenesis when the roots grow 5-6 cm long and do not return to land. At the beginning, the concentration of the nutrient solution should be lower. After the plants adapt to the growth environment in the water, the concentration can be increased according to the plants, and oxygenation can also be reduced, and finally stopped. When the roots grow long enough to be bottled, they can be bottled!

Planting with expanded clay: The rooting process before potting is the same as hydroponics. Do not plant the plant too low when potting, as that will be bad for the future growth of the plant. When the roots of the plant grow out of the pot, it can be sold.

During the production period, apply fungicide and spray foliar fertilizer once every week. For home maintenance, in addition to referring to the product manual, you should also follow its growth habits, stop fertilizing during the dormant season, place it in a place with strong sunlight, and use less water in winter and early spring for ceramsite planting. If it is placed in a dark place for too long, the leaves will turn yellow and lifeless. Moreover, the tips of the leaves at the base are prone to blackening, as if they were scalded by boiling water. Do not lack water during the growing season.

38. Alias ​​of Three-color Millennium Wood

Tricolor Dracaena alias: Tricolor Dracaena, Rainbow Dracaena, Colored Dracaena

Family: Agavaceae, Dracaena

Morphological characteristics: small evergreen tree. Thin stem, upright, up to 3 meters high. Leaves 15-60 cm long, 1-2 cm wide, sword-shaped. Green leaves with milky white, yellow-white, and red stripes. A unique variety in the genus Agave.

Distribution and habits: Native to Madagascar.

It likes a warm, humid environment with bright scattered light. It is relatively shade-tolerant and avoids strong direct sunlight. The suitable growth temperature is 18-28 degrees. The wintering temperature needs to be above 10 degrees.

Propagation method: Cuttings

Hydroponics points:

1) Water-growing is easy for the plant to take root, and the roots are white and ornamental. Changing the water is the key to success, especially when the plant is just being grown. Changing the water every other day can increase the nutrient content until the roots grow out. After the plant is adapted to water-growing, the water can be changed or added once a week or month according to the season.

2) When the water temperature is above 35 degrees in summer, the roots are prone to rot. At this time, you should stop using nutrient solution and only use clean water to grow the plants. In addition, you should increase the frequency of water changes to keep the water clear.

3) Place it in a brightly lit place indoors. Generally speaking, change the water once a month in autumn and winter. If you use a transparent container for water cultivation, wipe off the material attached to the container with a soft cloth while changing the water to make it transparent, so that the beauty of the plant's root system can be better displayed. After changing the water, you can drop a few drops of nutrient solution sold on the market or add some potassium dihydrogen phosphate diluted with 1000 parts of water into the water to provide the nutrients needed for plant growth. If you spray foliar fertilizer or 1000 parts of potassium dihydrogen phosphate as foliar topdressing during the growing season, it can make it grow stronger.

Can remove: toluene, xylene, benzene, trichloroethylene, formaldehyde
