1. Ecological habits:

1. Roses are highly adaptable to temperature and are easy to grow. They can be grown all over the country. In the north, the temperature is too low in winter and the leaves will fall and go dormant. If you grow them in pots, you can put them at home. In the south, when the summer is too hot, it is better to shade them.

2. Light Roses are light-loving plants. If they grow in a shaded environment, their branches will be thin, their leaves will be yellow and thin, their flowers will be small and not bright, and they may even fail to bloom. Potted roses should be grown on balconies or roofs, and should not be grown at home for a long time. Newly planted seedlings should not be exposed to the sun, but should be placed in a cool, well-lit place. They can only be exposed to the sun after new buds have grown or small leaves have begun to grow.

3. Soil: Roses like loose, well-drained soil (not easy to form hard clods after watering), and slightly acidic soil. Generally, the soil in the vegetable garden is good, or some soil dug from the roadside flower beds is also good.

4. Water When the rose is just planted, the first watering needs to be thoroughly watered, until a lot of water flows out of the small holes on the bottom of the flowerpot. After that, water it only when the soil is dry. In the first few days after planting, you can spray some water every day to increase the humidity of the air and the surface of the rose, reduce evaporation, and increase the survival rate. It is also okay not to spray.

5. Fertilization: When the newly grown branches of the seedlings are about 5 cm, you can apply the first fertilizer. The amount of fertilizer to be used can refer to the instructions on the fertilizer bag. Apply a small amount of fertilizer to the seedlings (not too much). For larger ones, you can also use the urine and feces of puppies and other animals, but don't use too much at a time, otherwise it will be bad to prevent burning the seedlings.

2. Potted seedling planting method

1. Choose a flower pot with an inner diameter of 24 to 30 cm and an inner height of 17 to 22 cm or larger. If it is inconvenient, you can also choose a smaller flower pot for small seedlings, with a pot diameter of more than 10 cm.

2. If the soil you bought from the market is very dry, you should water it first to make it fully moist before planting flowers. The dug soil should be finely ground and exposed to the sun for a few hours (for sterilization), and then it can be planted after the soil cools down.

3. Cover the small hole at the bottom of the flower pot with tiles or other things to prevent the soil from blocking the small hole below and preventing water from flowing out. If there is no hole at the bottom of the container used for planting flowers, you must drill a hole, otherwise the excess water will not flow out when watering, and the seedlings will be soaked to death.

4. Add soil to the flowerpot until the soil surface is 6 to 7 cm from the pot mouth. If the seedling has a pot, remove the small pot. Try not to loosen the soil in the pot. If the soil in the small pot is too dry, water it first and then remove the small pot. Place the seedling upright in the middle of the flowerpot so that the heel touches the soil surface. Hold the seedling in one hand and add soil with the other. While adding soil, gently lift the seedling to stretch the root system. Cover all the roots so that you can't see them. Don't plant too deep, which is not conducive to the survival of the seedling. (After the seedling survives and grows new branches and leaves, add 1 to 4 cm thick soil.) Then, gently compact the soil with your hands. Water it.

3: How to plant seedlings in the yard

1. Make a pile of soil, generally more than 30 cm high. (If you want to add organic fertilizer as base fertilizer, you can dig a hole first, put the fertilizer in the hole, then cover it with soil, and make a pile of soil on the hole). Dig a hole on the pile of soil and plant the seedlings in it just like planting seedlings in a pot.

2. Cover the roots completely when planting. Otherwise, planting too deep will be detrimental to the survival of the seedlings. Water after planting and find something (such as leaves and branches) to shade the seedlings from the sun (do not cover them with plastic bags, otherwise the temperature inside will rise very high when the sun shines, and the seedlings will die). After the seedlings survive, the shade can be removed. After new branches and leaves grow, add soil to the seedlings. Depending on the size of the seedlings, add 2 to 4 cm of soil.

4. Pruning Roses have many side buds. When you cut off the upper part of a branch, 1 to 3 buds below the cut will quickly grow into new branches, and the original branches will no longer grow. Therefore, pruning can control the height of the whole rose, increase the number of side branches, and also increase the number of flowers.

6. Prevention and control of diseases and pests. The main diseases of roses are powdery mildew, root cancer and red spider mites. Powdery mildew is the most common. There are many commonly used drugs. We mostly use Baiheiling and Cuibei, which are effective.

1. Rose powdery mildew is a fungal disease caused by pathogenic bacteria. It mainly infects young leaves, tender stems and flower buds, and white powdery spots will appear on the infected parts. When seriously infected, the leaves will become brittle, shrink, curl and dry up. To prevent and control rose powdery mildew, you must pay attention to pruning to keep the plants well ventilated, and avoid planting roses in places with insufficient light or isolating them from other plants that are susceptible to powdery mildew. Choosing disease-resistant varieties can reduce the threat of powdery mildew, or spraying the whole plant with 1000 times of Mianlaid (Yili).

2. Red spider mites: They mainly harm the front and back of leaves, causing them to dry and fall off. In the early stage of the disease, spray with 800-1000 times diluted 20% trichlorofenicol wettable powder, once every two weeks, for two times in a row.

3. Root cancer

Caused by soil bacterial pathogens, it mainly attacks the stems and roots, often occurring where the plant contacts the soil. The infected part swells to form tumors that surround the stem, causing poor plant growth and death. Since it is difficult to treat plants infected with root nodule, it is best to remove and burn the diseased plants as soon as they are discovered, and use soil disinfectants to disinfect the planting holes before planting. The main way to prevent root nodule disease is to be careful when purchasing seedlings, and to avoid causing wounds on the stems before and after planting, especially in areas close to the soil. In addition, it is not advisable to use soil near the diseased plants to cover the soil to avoid infection.

Introduction from Flower and Bonsai Network: Today the editor of Flower and Bonsai Network will introduce to you an article about the colors of roses. Flower lovers can take a look at it together.

Roses are very common flowers, but in people's eyes, they have many types. In terms of color, what colors do roses have?

Red Rose

Basically, red roses are the most common roses. They are a very common cut flower and a flower used by lovers to express love. In fact, real red roses do not exist. The cut flowers on the market are actually Chinese roses, and the red roses in herbal tea are mostly Pingyin roses.

Yellow Rose

Yellow roses are also a common flower with elegant posture and bright colors. They are often used to express friendship. In fact, yellow roses among cut flowers are mostly a type of cut rose.

Purple Rose

Purple rose is also a variety of roses. Its flowers are relatively small, but the fragrance is relatively strong. Purple rose has many functions, including beauty and regulating the human body.

White Rose

White roses are also a type of rose that cannot be forgotten. They like sunlight but are afraid of cold. When growing them, they grow better in loose, fertile, neutral or slightly acidic soil. In fact, the most common cut white roses are white roses.

Black Rose

Black rose is actually black rose. There are two common cut black roses, each with its own unique appearance and ornamental value.

Green Rose

Legend has it that the green rose comes from Israel and is also called Bi Hai Yun Tian. However, the real green rose does not actually exist. The green rose in cut flowers is actually the Chinese rose.

Orange Rose

Orange rose is also a variety of rose, and its flower language is friendship and youthful beauty.

Blue Rose

The blue rose is a genetically modified rose that has been implanted with a gene that produces blue pigment, so the petals appear blue.

Blue Rose is not a blue rose, but a rose that has been artificially dyed, dyeing the white rose blue.

Colorful Roses

The colorful rose is also a kind of rose produced by color adjustment. It is also transformed from the white rose. When it is cultivated, pigments and fuel are added to the water. When the petals absorb water, they will turn into these colorful colors.

What types of roses are there? What are the effects and functions of roses?

Rose belongs to the genus Rosaceae. All families are widely used ornamental plants in horticulture. There are many varieties, about 4,000 species, and there are also 100 to 200 species commonly cultivated. There are many varieties of roses, usually the following types.

(1) Red rose, the flower is red and purple.

(2) Purple rose: the flower is purple.

(3) White rose, white flowers.

4) Double white rose, double petals, white.

(5) Thornless rose: The stems and branches are thornless.

Rose, prickly rose, wild rose Habits: Rose is native to the northwest, mainly distributed in the vast area, is a small deciduous shrub, strong and adaptable. The suitable temperature for rose growth is 20-25 degrees Celsius, and it is cold-resistant and will not freeze even at -20 degrees Celsius in winter. It likes sunshine and is also tolerant to drought. It is relatively drought-resistant, so the soil should not be too wet, let alone waterlogging. It is suitable to choose high and dry terrain, good ventilation, and fertile sandy loam for cultivation.

What are the effects and functions of roses?

In addition to the beautiful flowers that can be used for viewing, most of the plants in this genus have fragrance and can be used to make tea. Among them, roses have the strongest fragrance. In addition to being used for smoking tea, they can also be roasted and dried into flowers, but the value of smoked tea is not high and they are only suitable for smoking black tea. Roses have a wide range of other uses. The flowers and fruits can be used for medicinal purposes, mainly treating liver and stomach pain, new and long-term rheumatism, injuries from falls, irregular menstruation, breast pain and swelling, etc. The petals are mashed into juice and sugar is added to make rose seeds, which can be used as fillings for cakes, steamed into dumplings, brewed into rose wine, and can also be used to extract spices and sweets. The bark of the roots can also be used as a yellow-brown dye to dye silk and other items.

Roses have certain economic value. The flowers can be used to extract aromatic oil and process into rose sugar, rose dew, etc. Both the buds and roots can be used as medicine, which has the functions of regulating qi, dredge meridians, invigorate blood circulation, and invigorate the spleen.

How to prune roses correctly

Roses are very beautiful. In order for roses to grow better, they need to be pruned frequently to supply nutrients to new branches and provide ventilation. More pruning can make roses grow more vigorously and bloom more beautifully. Usually, pruning can be started when the flowers are very large.

Roses prefer warm and humid environments, are easy to reproduce, are not very demanding on soil, and can be cultivated in general soil.

Planting time: After the leaves fall in autumn and before the buds sprout in spring.

Before planting, the land should be carefully prepared and sufficient base fertilizer should be applied (20 catties of farmyard manure per plant). The planting density depends on the variety. Purple roses and red roses have weak germination ability, and the spacing between plants is generally 1.2 meters. White roses have strong germination ability. For newly planted roses, you can continue to water them lightly after they are alive, and weed and loosen the soil frequently to retain moisture. When the seedlings grow to 2 feet, pinch off the top to promote more branches. At this time, you can apply chemical fertilizer (25-30 catties per mu). After the frost, prune the overcrowded branches, horizontal branches, and diseased and insect-infested branches to ensure ventilation and light transmission between plants, uniform flowering, and increased flower production. However, white roses should not be heavily pruned, and dry branches and diseased and insect-infested branches can be removed. If the old roses grow weakly and produce less flowers, they should be updated in time, the old rhizomes should be removed, and the lateral rhizomes should be encouraged to produce young plants.

Rose pruning method

For large roses, the roses can only bloom very large if each branch is pruned to leave only one main bud; for medium roses, more flowers can be left.

Generally, rose pruning should be avoided in summer, because the hot and rainy summer climate can easily cause pruning in the rose growth environment, and the wounds are easily invaded by diseases.

Pruning and shaping is an important method of plant maintenance and management, just like human dressing. The time of flower pruning can be determined according to needs and can be carried out all year round, but mainly in winter and summer. Winter is the most important time for pruning. Pruning is generally carried out after the leaves fall in autumn and before the buds sprout in early spring. Pruning can maintain the good tree shape and vigorous growth of plants, ventilate and transmit light, prevent diseases and pests, save nutrients, promote the flowering of ornamental shrubs, maintain the height of the plants, and promote regeneration.

The specific contents include:

(1) Pruning: Cutting off the tip of a branch or most of a branch.

(2) Thinning. When the branches inside the plant are too dense, they should be thinned out from the base to remove crossing branches, inward branches, diseased and insect-infested branches, overgrown branches, and senescent branches.

(3) Pinching and topping. Pinching is to inhibit the rapid growth of new branches and remove the growth points at the top of the branches. Topping is to remove the tops of new branches.

(4) Bud removal and bud stripping. Bud removal is to remove the excessive side buds or new young branches on flowers and trees to reduce nutrient consumption. Bud stripping generally refers to stripping the side buds to prevent too many side buds from affecting the growth of the main buds.

(5) Flower thinning. Most fruit-bearing flowers produce more flowers than fruits. If flower thinning is not performed, they will all grow into young fruits, most of which will fall off naturally, wasting a lot of nutrients in vain, and the remaining fruits will not be of guaranteed quality. Therefore, overcrowded flowers should be thinned out during the flowering period.

(6) Root pruning. Root pruning is mainly done when transplanting or repotting. That is, when transplanting, the roots that are too long, damaged, or rotten should be trimmed off. If there are roots that are too old and too dense, they should also be thinned out.

Generally speaking, flower pruning should follow the principle of "first up and then down, first inside and then outside, remove the weak and keep the strong, remove the old and keep the new". The pruning cut must be close to the node, the cut should be at a 45-degree angle on the opposite side of the cut bud, the cut should be flat, and the cut of the large branch needs to be treated with lanolin, wax, etc. to facilitate healing as soon as possible.
