A complete guide to basic flowergrowing knowledge for beginners, save it!

Known as the "Mother of World Gardens", it has rich flower resources and a wide variety of species. In order to facilitate cultivation, management and utilization, it is necessary to understand the classification of flowers. Due to different classification bases, the classification methods are also different.

According to the morphological characteristics of flowers, they are usually divided into two categories: herbaceous flowers and woody flowers. Flowers with soft stems are called herbaceous flowers, while flowers with hard stems are called woody flowers.

According to the growth habits and morphological characteristics of flowers, they can generally be divided into herbaceous flowers, woody flowers, succulent flowers and aquatic flowers. Herbaceous flowers can be divided into annual and biennial grass flowers, perennial flowers, bulbous flowers and lawn plants according to their growth and development cycles. Woody flowers can be divided into trees, shrubs and vines according to the height of their trunks and the size of their crowns. Succulent flowers have fleshy stems and leaves, and store abundant water in their bodies. Some leaves degenerate into thorns or feathers with peculiar shapes, so they form a category of their own in horticultural cultivation. Aquatic flowers grow in water and swamps all year round, and most of them are perennial plants.

According to the classification of ornamental parts, flowers can be divided into flower-viewing types (mainly for viewing the flower color and shape, such as chrysanthemum, rose, etc.), leaf-viewing types (mainly for viewing the leaf color and shape, such as croton, variegated taro, etc.), fruit-viewing types (mainly for viewing the fruit, such as kumquat, etc.), stem-viewing types (mainly for viewing the branches and stems, such as the bachelor tree, mountain shadow boxing, etc.) and bud-viewing types (mainly for viewing the buds, such as silver willow.

According to their uses, flowers can be divided into cut flowers (such as carnations, calla lilies, etc.), indoor flowers (such as Clivia, Monstera, etc.), garden flowers (such as roses, chrysanthemums, etc.), medicinal flowers (such as peonies, honeysuckle, etc.), spice flowers (such as white jasmine, jasmine, roses, etc.) and edible flowers (lilies, day lilies, pomegranates, etc.).

In addition, based on the climatic conditions of the flowers' origins and their natural distribution, flowers are divided into tropical flowers, subtropical flowers, warm temperate flowers, temperate flowers, subarctic flowers, alpine flowers, etc. This classification method can reflect the habits of various flowers and the conditions that need to be met for their growth and development during cultivation.

What is the relationship between temperature and growing flowers?

Temperature is an important condition for the survival of various flowers. No matter how suitable other environmental conditions are, if there is no suitable temperature condition, flowers will find it difficult to survive. Each flower has its optimum temperature, maximum temperature and minimum temperature for growth and development. According to the temperature conditions of the flower's origin, flowers can be roughly divided into high temperature type, medium temperature type and low temperature type.

(1) High temperature type.
Such as Milan, Poinsettia, Cineraria, Gloxinia, Fuchsia, etc. When cultivated in North China, the minimum room temperature in winter should be kept above 12℃.

(2) Medium temperature type:
Such as white orchid, jasmine, hibiscus, geranium, etc. The room temperature should not be lower than 5℃ in winter.

(3) Low temperature plants.
For example, oleander, osmanthus, kumquat, daisy, cycads, etc., the room temperature should not be lower than 0 degrees in winter. If the temperature is too high or too low, the normal physiological activities of flowers will be destroyed, growth will stop, and in severe cases, the whole plant will die.

What effect does light have on the growth and development of flowers?

Light is the energy source for flowers and plants to produce nutrients. Without light, photosynthesis cannot be carried out, and the growth and development of flowers will be seriously affected. Most plants can only bloom and flourish under sufficient light conditions. Different types of flowers have different requirements for light. A flower proverb says: "Shadow camellia, Yang peony, semi-shade and semi-sun four-season orchid". According to the different requirements of flowers for light intensity, flowers can be roughly divided into positive flowers, neutral flowers and negative flowers.

(1) Positive flowers.
Most flowers and fruit-bearing plants are positive flowers, such as magnolia, rose, pomegranate, plum, crape myrtle, citrus, etc. There are also a few positive flowers among foliage flowers, such as cycads, palms, croton, etc. Most aquatic flowers, cacti and succulents are also positive flowers. All positive flowers like strong light and cannot tolerate shade. If there is insufficient sunlight, it is easy to cause the branches and leaves to grow too long, the tissues to become soft and weak, the leaves to become pale and yellow, it is difficult to bloom or the flowering is poor, and it is easy to be affected by diseases and insect pests.

(2) Negative flowers. These flowers
grow best in shaded environments, such as asparagus fern, camellia, azalea, hosta, green radish, dieffenbachia, ivy, gloxinia, monstera, begonia, etc. If they are exposed to strong light for a long time, their branches and leaves will turn yellow, their growth will stagnate, and in severe cases, they may even die.

(3) Neutral flowers.
They grow best in full sunlight, but they need some shade when the light intensity is high in summer, such as osmanthus, jasmine, white orchid, hydrangea, etc. In summary, different flowers have different requirements for light, and even the same flower has different requirements for light at different stages of growth and development. The amount of light required by seedlings can be gradually increased, while the positive chrysanthemum requires short-day conditions to form flower buds.

What effect does light have on flower bud differentiation?

The purpose of cultivating flowers is to make them bloom more flowers, and light is the most effective external factor to promote the formation of flower buds. On the same flower, branches that receive sufficient light will have more flower buds, while branches that do not receive enough light will have fewer flower buds. When there are many sunny days in summer, flowers receive sufficient light and will have more flowers next year. Generally speaking, flower plants can carry out photosynthesis under the temperature conditions of 10-35℃, and the most suitable temperature is 20-28℃.

Flowers can be divided into three categories according to their requirements for the length of light exposure:
(1) Long-day flowers.
Generally, flowers that need more than 12 hours of sunlight per day to form flower buds are called long-day flowers. Many flowers that bloom in spring and summer are long-day flowers, such as irises, asters, and impatiens.

(2) Short-day flowers.
Flowers that can only form flower buds when the sunlight hours are less than 12 hours a day are called short-day flowers. Poinsettia and chrysanthemum are typical short-day flowers. They can only grow under long-day sunlight in summer but cannot differentiate flower buds. After autumn, when the sunlight hours are reduced to 10-11 hours, they begin to differentiate flower buds.

(3) Medium-day flowers.
Flowers whose flower bud formation is not strictly dependent on the length of daylight are called medium-day flowers. For example, calla lily, carnation, zinnia, rose, hibiscus, etc., they have no obvious response to the length of light exposure and can bloom all year round as long as the temperature is suitable.

Effects of water on the growth and development of flowers

Water is a necessary condition for the growth and reproduction of flowers. It has a great impact on the growth and development of flowers. Because water absorption exceeds consumption, there is too much water in the body of flowers, which makes the plants particularly long and thin, and their cold resistance and stress resistance are weakened. If there is too much water for a long time, it will cause root rot, leaf fall, and even death. If water absorption is less than consumption, due to lack of water, the flowers will wilt, and severe water shortage will cause the flowers to wither and die. There are many varieties of flowers, and the water requirements are also different. Even the same flower has different water requirements at different stages of its growth.

According to the different water requirements of flowers, flowers can be roughly divided into three categories: xerophytic, aquatic and mesophytic:

(1) Drought-tolerant flowers:
Plum blossoms, crape myrtles, crabapples, hollyhocks, nandina domestica, and succulent flowers are relatively drought-tolerant.

(2) Aquatic flowers,
such as lotus, water lily, calamus, water bamboo, etc.

(3) Mesophytic flowers.
Flowers that grow well in moist soil. Most flowers belong to this type, such as magnolia, white orchid, wintersweet, peach blossom, camellia, and bauhinia.

The influence of air humidity on flowers

Most of the water needed by flowers comes from the soil, but air humidity also has a great impact on the growth and development of flowers. If the air temperature is too high, it will easily cause the branches and leaves to grow too long, the petals to rot and fall, and it will easily cause the spread of pests and diseases. If the humidity is too high during the flowering period, it will hinder flowering and affect fruiting. If the air humidity is too low, the flowering period will be shortened and the color of the flowers will become lighter. If the air is dry for a long time when southern flowers are raised in the north, they will grow poorly, affecting flowering and fruiting. The climate in the north is dry in winter. If the humidity is not maintained at a certain level indoors, some flowers that like moisture will often have pale yellow leaves and dry leaf edges.

According to the different requirements of different flowers for air temperature, you can take methods such as spraying branches and leaves or covering with plastic film to increase air humidity and create humidity conditions suitable for their growth. Orchids, begonias, monstera and other moisture-loving flowers require air relative humidity of no less than 80%; jasmine, white orchid, hibiscus and other medium-humidity flowers require air humidity of no less than 60%.

Why do flowers die from overwatering?

If potted flowers are watered too much, the water fills up the gaps in the soil, and the air in the soil is replaced by water. At this time, the outside air cannot enter, resulting in soil hypoxia, which hinders the respiration of the roots, reduces physiological functions, and hinders the root system's ability to absorb water and fertilizer. At the same time, due to the lack of oxygen in the soil, aerobic bacteria with the function of decomposing organic matter in the soil multiply and become active, increasing the acidity of the soil. Due to the rampant activity of butyric acid bacteria, a series of toxic substances such as hydrogen sulfide and ammonia are produced, which directly poison the root system. At the same time, due to the lack of oxygen, the plants consume a large amount of soluble sugar in the body and accumulate too much alcohol and other substances, which greatly reduces photosynthesis, and finally causes the flowers to die of hunger.

In the practice of flower cultivation, we often see cases where the roots of flowers turn black and rot, and the flowers are "drowned" due to excessive watering. Therefore, when cultivating flowers, we should pay attention to the appropriate amount of watering.

What are the dangers of insufficient watering of potted flowers?

Since potted flowers have less soil and cannot store much water, it is necessary to replenish water regularly during the growing season to ensure normal growth of the flowers.

If the water supply is insufficient, the leaves and petioles will shrink and droop, and the flowers will wilt. If the flowers are not watered for a long time, the leaves of older plants and the lower parts of the plants will gradually turn yellow and dry up. If most grass flowers are in a state of drought for a long time, the plants will be short, the leaves will lose their bright green luster, and even the whole plant will die.

Some flower growers are afraid of overwatering, so they water only halfway, that is, the amount of water they pour can only moisten the topsoil, while the lower soil is dry. This watering method will also affect the development of the flower roots and cause the above-mentioned undesirable phenomena. Therefore, watering should be done when the soil is dry and when it is wet, water thoroughly .

How to judge whether potted flowers are lacking water?

Watering is a regular management task for flower cultivation. It is difficult to determine whether the pot soil is lacking water, so many flower lovers often feel distressed about this. Here is a brief introduction of the experience of flower experts in judging whether the soil is lacking water.

(1) Tapping method.
Use your finger joints to gently tap the middle part of the pot wall. If a crisp sound is heard, it means the soil is dry and needs watering immediately. If a dull sound is heard, it means the soil is damp and you do not need to water it for the time being.

(2) Visual inspection:
Use your eyes to observe whether the color of the potting soil changes. If the color becomes lighter or grayish white, it means that the potting soil is dry and needs watering. If the color becomes darker or brown, it means that the potting soil is moist and you don’t need to water it for the time being.

(3) Finger test method.
Gently insert your finger into the soil about 2 cm deep and touch the soil. If it feels dry or rough and hard, it means the soil is dry and needs to be watered immediately. If it feels slightly damp, fine and soft, it means the soil is moist and you do not need to water it for the time being.

(4) Pinching and twisting method.
Use your fingers to twist the soil in the pot. If it becomes powdery, it means that the soil is dry and you should water it immediately. If it becomes flakes or granules, it means that the soil is moist and you do not need to water it for the time being.

The above test methods are all based on experience. They can only tell people the approximate dryness or wetness of the potting soil. If you need to know the exact dryness or wetness of the potting soil, you can buy a soil thermometer, insert the thermometer into the cover, and you can see the words "dry" or "wet" on the scale, so you can know exactly when to water.

What kind of water is best for watering flowers?

Water can be divided into hard water and soft water according to the salt content. Hard water contains more salts. When used to water flowers, it often causes brown spots on the leaves of flowers, affecting the ornamental effect. Therefore, soft water is more suitable for watering flowers. Among soft waters, rainwater (or snow water) is the most ideal, because rainwater is a kind of water that is close to neutral, does not contain minerals, and has more air, which is very suitable for watering flowers. If rainwater can be collected and stored on rainy days for watering flowers, it will help promote the assimilation of flowers, extend the cultivation period, and improve the ornamental value. In particular, flowers that prefer acidic soil prefer rainwater. Therefore, more rainwater should be stored for use in the rainy season.

In the Northeast, snow water can be used to water flowers, and the effect is also very good, but it should be noted that the ice and snow must be melted and left until the water temperature is close to room temperature before use. If there is no rain or snow water, river water or pond water can be used.

If you use tap water, you must first store it in a bucket (tank) for 1-2 days to allow the chlorine in the water to evaporate before using it, which is safer.

Do not use laundry water containing soap or detergent when watering flowers, nor use dishwashing water containing oil. For cacti and other flowers that prefer slightly alkaline conditions, it is not advisable to use slightly acidic leftover tea water.

In addition, you should also pay attention to the temperature of the water when watering flowers. Whether it is summer or winter, if the water temperature is too different from the air temperature (more than 5 degrees), it is easy to damage the roots of flowers. Therefore, it is best to put the water for watering flowers in a bucket (tank) and dry it for a day, and then use it when the water temperature is close to the air temperature.

How to control the amount of watering for potted flowers

Whether potted flowers can be watered at the right time and in the right amount is the key to the success of flower cultivation. Based on the experience of various places, the amount of watering for potted flowers is determined by comprehensively judging the flower variety, plant size, growth and development period, climate, soil conditions, flower pot size, placement location and other aspects to determine the time, frequency and amount of watering.

Under normal circumstances, flowers that like moisture should be watered more, while flowers that like drought should be watered less; bulbous flowers should not be watered too much; herbaceous flowers have high water content and high transpiration rate, so they need more water than woody flowers; flowers with large, soft, smooth and hairless leaves should be watered more, while flowers with small leaves with a waxy layer, fuzz, and leathery texture should be watered less; water more during the growth period and less during the dormant period; water more when the seedlings are large and the pots are small, and water less when the seedlings are small and the pots are large; water more when it is hot and less when it is cold; water more on dry days and less on cloudy days, etc.

For general flowers, the water supply in four seasons is: after the beginning of spring, the temperature gradually rises, and the flowers enter the growth period, and the amount of watering is gradually increased. Watering in early spring should be done before noon. In summer, the temperature is high, the flowers grow vigorously, and the transpiration is strong, so the amount of watering should be sufficient. In summer, watering should be done in the morning and evening. After the beginning of autumn, the temperature gradually drops, and the flowers grow slowly, so watering should be reduced appropriately. In winter, the temperature is low, and many flowers enter a dormant or semi-dormant period. Watering should be controlled. Do not water if the pot soil is not too dry, so as to avoid root rot and leaf fall due to excessive watering. In winter, watering should be done at 1-2 pm.

What is the purpose of water spray?

Spraying water can increase air humidity, lower the temperature, wash away dust and pests on plants, prevent young leaves from burning and flowers from withering early, and keep plants fresh; especially for some flowers that like shade and humidity, such as camellia, azalea, orchid, monstera, etc., spraying water on the leaves frequently is very beneficial to their growth and development. In summer, when it suddenly clears up after rain or it is hot at night, you should also pay attention to spraying water to cool down and prevent diseases.

The amount of water to be sprayed should be determined according to the needs of the flowers. Generally, the water evaporates soon after spraying, and this amount of water is the most suitable. Seedlings and delicate flowers need more watering, as do newly potted and unrooted cuttings. Tropical orchids, Araceae and Bromeliaceae flowers need more frequent watering.

However, some flowers are very sensitive to water and humidity, such as Gloxinia, Calceolaria, Begonia, etc., whose leaves have thick hairs, and it is not easy for water to evaporate after falling on them, which may cause the leaves to rot, so it is not advisable to spray water on the leaves. For blooming flowers, it is also not advisable to spray too much water, otherwise it is easy to cause the petals to rot or affect fertilization, reducing the fruiting rate. In addition, the leaf buds at the top of the cyclamen tuber, the flower buds in the gerbera leaf cluster, and the pseudobulbs in the center of the Clivia leaf cluster are all afraid of water and humidity. These parts are easily damaged after spraying water.

How to save flowers after they wilt

Potted flowers, because there is less water in the pot, forget to water, especially in the hot summer, often cause the leaves to wilt. If not saved in time, it will often lead to plant withering over time. If it is not saved properly, it may sometimes cause the death of the plant.

The correct approach is: when you find the leaves are wilting, you should immediately move the flowerpot to a cool place, spray some water on the leaves, and water it lightly. As the stems and leaves gradually recover, gradually increase the amount of watering. If you water too much water at once, it may cause the plant to die.

This is because, after the flowers wilt, a large number of root hairs are damaged, so the water absorption capacity is greatly reduced. Only after the new root hairs are grown can the original water absorption capacity be restored. At the same time, wilting causes cells to lose water. After encountering water, the cell wall absorbs water first and expands rapidly, and the protoplasm absorbs water later and expands slowly. If a large amount of water is suddenly poured at this time, it will cause plasmolysis and damage the protoplasm, thus causing the death of the flowers.

The role of soil

Soil is an important matrix for cultivating flowers, the material basis for the survival of flowers, and the main source of water, fertilizer, air, and heat required for the growth and development of flowers. This is because soil is composed of minerals, organic matter, soil moisture, and soil air. Minerals are the most basic substances that make up the soil, and they can provide a variety of nutrients required by flowers. Organic matter not only supplies nutrients for the growth of flowers, but also plays an important role in improving the physical and chemical properties of the soil and the structure of soil aggregates, as well as water retention, water supply, ventilation, and temperature stability. Soil moisture is an indispensable material condition for the growth of flowers. Soil air is the source of oxygen required for the absorption of flower roots and the life activities of microorganisms. It is also an important condition for the further weathering of soil minerals and the conversion of organic matter to release nutrients.

Scientific experiments have shown that the soil suitable for plant growth, by volume, contains about 38% minerals, 12% organic matter, and 15% to 35% air and moisture. According to some>

The preparation of culture soil should be flexible according to the growth habits of flowers, the properties of the culture soil materials and local conditions. For general potted flowers, the commonly used culture soil configuration ratio is leaf humus (or peat soil): garden soil: river sand: bone meal = 35:30:30:5, or leaf humus (or peat soil), plain sandy soil, decomposed organic fertilizer, superphosphate, etc. are mixed and sieved at 5:3.5:1:0.5 before use.

The above-mentioned culture soil is mostly neutral or slightly acidic, suitable for most flowers. For cultivating acid-loving flowers and trees such as camellia and azalea, about 0.2% sulfur powder can be added; for cultivating flowers such as cactus, about 10% wall soil peeled off from lime walls can be added.

Note: There are different opinions about the suitable pH value for some flowers and trees. The above>

(1) Selection of indoor flowers:
Indoors are an important place for people to engage in activities in their lives, and flowers should be selected according to the following requirements.

Flowers should be shade-loving or shade-tolerant varieties, such as evergreens, orchids, monstera, spider plants, rubber trees, Clivia, etc. Some ornamental flowers are mostly positive flowers, so they should be placed in sunny places when displayed indoors, and often moved outdoors to absorb sunlight and rain.

Flowers and trees with peculiar smells should not be placed indoors. For example, the fragrance of cloves and tuberose can cause adverse reactions in some patients. Some patients with hypertension and heart disease feel stuffy and uncomfortable after smelling these fragrances. The fragrance of pine and cypress plants can reduce people's appetite, so it is not advisable to place too many or too long indoors.

The leaves, stems and juices of some flowers are toxic. They should be properly isolated when placed indoors, especially to avoid contact with children. Poinsettia, five-color plum, oleander, tiger thorn, king whip, Lycoris, etc. are all toxic, but in fact, the toxicity is relatively low. As long as the leaves, branches, flowers and fruits are not picked casually, it will generally not cause poisoning. More attention should be paid when cultivating.

The bedroom should be clean, elegant and comfortable. South-facing bedrooms have plenty of light, so you can choose flowers that like sunlight and warmth, such as Milan, hibiscus, rose, white jasmine, kumquat, cactus and succulents. East-west-facing bedrooms have short sunlight hours, so you can choose semi-shade-tolerant flowers, such as camellia, azalea, gardenia, Michelia, asparagus, and dieffenbachia. North-facing bedrooms have poor lighting conditions and low temperatures, so you should choose Clivia, Chlorophytum, Rubber Tree, Monstera, Asparagus and rock bonsai.

The living room layout should be quiet, elegant and generous, with small and elegant as the main features. You can choose Milan, Osmanthus fern, jasmine, asparagus fern, bergamot, kumquat, etc. You can place foliage plants in the corners, such as money tree, areca palm, bamboo palm, miniature coconut palm and ferns.

(2) Balcony flower selection:
The balcony is small in size, windy and dry, with high temperatures in summer and fast evaporation of water, but it has sufficient light and good ventilation, which is very beneficial for some light-loving and drought-resistant flowers.

The convex balcony is exposed on three sides and has good sunlight. You can build a flower rack to plant climbing flowers, such as morning glory, grapes, and five-leaf ivy. You can also set up a flower rack to display roses, pomegranates, Milan, jasmine, and bonsai. You can hang shade-tolerant spider plants and ferns on the top of the balcony. The back of the balcony is a semi-shady environment, where you can place Nandina domestica and Clivia.

The recessed balcony has only one side exposed and the ventilation conditions are poor. You can build trapezoidal flower racks on the walls on both sides to display flowers and trees.

What kind of soil do plants need?

1. Good drainage and air permeability

If flowers want to grow quickly and healthily, they must have soil with good drainage and air permeability. Otherwise, the respiration of the plant roots will be affected, and the plants will not be able to absorb nutrients and water well, which can easily lead to yellowing of the plants, root rot, and even the entire plant drying up and dying.

2. High in nutritional value

Soil rich in organic matter can continuously provide nutrients for flowers and promote their better growth. Generally, fertile soil is darker in color and loose in texture.

3. The soil is slightly acidic or neutral

Generally speaking, soils with high organic matter content are acidic, while poor soils are mostly alkaline. And most plants prefer acidic or neutral soils.

Common types of soil for growing flowers

1. Sandy soil:

The texture is relatively pure, without organic matter and nutrients, but the drainage and air permeability are relatively good. Infiltrating sand into the soil can prevent the soil from becoming compacted and increase ventilation and air permeability.

2. Leaf mold:

It is natural soil in nature, generally formed by the accumulation of fallen leaves, dead branches and fallen leaves over many years. This kind of soil contains a lot of nutrients, has a loose texture, good drainage, and is usually acidic, making it suitable for growing flowers that prefer acidic soil.

3. Moss soil:

It is usually collected from peat bogs, is dark brown in color, and is rich in organic matter, which can improve soil fertility. Because it is formed by the accumulation of organic matter in a swamp environment, it contains a lot of fiber and has high nutritional value, making it a good soil for flower growth.

4. Humus soil:

It refers to the soil formed by fermentation of a mixture of livestock manure, urine, and feed. This soil has high nitrogen and phosphorus content, loose texture, and high nutritional value, but poor drainage.

5. Garden soil:

Most of them come from farmland and wilderness, and are the most common soil for growing flowers. They contain high levels of organic matter, but their drainage performance is not strong, and the soil is prone to compaction.

6. Pond mud:

Also known as river mud, it generally comes from ponds and other places in South China. It refers to the soil that has been deposited at the bottom of the pond for many years. This soil is slightly acidic and rich in nutrients. It is more suitable for cultivating flowers that like shade and moisture, such as lotus and bowl water lily .

7. Mountain mud:

It refers to the soil produced in mountainous areas such as Zhejiang, which is formed by the decay of fallen leaves accumulated over many years. It is dark brown in color, loose in texture, and has good drainage and air permeability. It is a kind of soil that is very suitable for flower cultivation.

8. Pine needle soil:

This type of soil generally comes from mountain forests, where the fallen leaves of pine trees rot and form this type of soil. It contains more organic matter and is more fertile.

9. Special nutrient soil:

The special nutrient soil sold on the market is artificially processed, and generally includes special nutrient soil for Clivia, special nutrient soil for succulents, etc.

How to choose soil

1. Choose according to the habits of flowers.

Generally speaking, the habits of flowers and plants are divided into acid-loving, alkaline-loving, and neutral. For example, white orchid, gardenia, crabapple, etc. are flowers and plants that prefer acidic soil; lilac, albizzia, etc. are flowers and plants that prefer alkaline soil; osmanthus, etc., are a few flowers that prefer neutral soil. When choosing soil, you must understand the habits of the flowers you are raising, so that you have a basic direction when choosing the soil.

2. Choose according to the fertilizer requirements of flowers.

Generally speaking, the amount of fertilizer required by flowers determines the choice of soil. For example, the ornamental value of some flowers lies mainly in their leaves and overall shape, so they do not need too fertile soil; while the ornamental value of some flowers lies mainly in their flowers and fruits, so in this case, they must be cultivated in soil with strong fertility and high nutrient content.

3. Choose according to the cultivation needs of flowers.

For example, large flowers and trees, and flowers and trees that are difficult to transplant will carry the soil balls with them when transplanted, so the soil cannot be too loose; the soil for turf plants must be fine and sticky, which places more stringent requirements on the soil; flowers with sparse roots must choose soil with a certain viscosity; small seedlings and easy-to-survive flowers can choose sandy soil.
