How to raise Chinese rose culture methods and matters needing attention

Rose can be regarded as the most common kind of flower. in the past, people who usually loved flowers would raise some rose. With the development of the times, the planting base of rose has been constantly broken through, and the rose has gradually got rid of the identity of domestic plants. It has become a very widely used plant in garden layout, and the breeding rose has set off a new wave.

How to raise rose flowers

Rose has strong adaptability, cold and drought resistance, and low demand for soil conditions, but the slightly acidic sandy soil with rich organic matter and good drainage is more favorable for its growth. Like the sun, but excessive direct light will also affect the normal development of buds, easy to scorch the petals. Generally speaking, 22-25 ℃ is the best ambient temperature for rose growth, and the high temperature in summer will affect flowering.

Rose can blossom continuously, but to ensure air circulation and pollution-free growth environment, the unfavorable cause of powdery mildew is poor ventilation, and the toxicity of harmful gases (sulfur dioxide, chlorine, fluoride, etc.) in the air can not be ignored.

Culture method of Chinese rose

1. Selection of basin soil

The choice of flowerpot does not have to be very gaudy, permeable, breathable ordinary mud pot is OK. Before using the new mud basin, soak it with water before using it. Just cut the small buy oh choose about 15cm small flowerpot, 1 ~ 2-year-old rose seedlings choose 18cm 20cm flowerpot, gradually increase according to the size of the plant.

Rose flowers like moist soil, very afraid of drought or stagnant water, so we must ensure that the soil is loose, good drainage, but also has a certain role in water and fertilizer conservation.

2. Temperature requirement

The most suitable growth temperature of Chinese rose is 18-20 ℃, so the flowers are larger and brightly colored in April-May and September-October every year. With the increase of temperature, when the temperature is stable at about 30 ℃, the color of the flowers is small, the taste is light, the ornamental value is low, and they are vulnerable to diseases and pests.

In the high or low temperature environment, rose flowers enter dormancy, there may be fallen leaves, there is no need to worry.

3. Lighting requirements

Rose is a sunny plant, the growth needs plenty of sunlight, the daily light time can not be less than 5-6 hours, otherwise the branches and leaves are thin, there will be only growing branches. General potted rose maintenance, put it in a sunny place, summer shade, cooling can be.

4. Watering method

Spring is the season of sprouting and growing branches of rose flowers, and the supply of water is very important. In March, the new leaves grow and water once every two days, in the morning; in April, the flower buds gradually form and water once a day; in May, they enter the flowering stage, watering twice a day, usually once at about 8 o'clock in the morning, and replenish water according to the dry and wet condition of the basin soil at about 4 o'clock in the afternoon.

In other seasons, according to the principle of "no dry, no watering, watering thoroughly", when the summer weather is hot, you can spray water to cool down properly.

5. Fertilization method

The rose should be fertilized with thin fertilizer and diligent fertilizer.

Before sprouting in spring, fertilize once and choose mature human dung, bean cake and so on. When the bud is ready to bloom, add a light liquid fertilizer. After the summer flowers wither, apply a rotten liquid fertilizer to promote autumn flowering. A small amount of organic fertilizer was applied to the roots in winter to enhance the disease resistance of the plant.

6. Pest control

In the case of poor ventilation and insufficient light, rose flowers are easily disturbed by diseases and insect pests, such as aphids, powdery mildew, black spot, etc., when diseases and insect pests occur, they are sprayed in time to avoid affecting flowering.

Matters needing attention in the culture of Chinese rose

1. Rose flowers have strong cold tolerance and can withstand the low temperature of-10 ℃. Generally speaking, the south does not have to move indoors to survive the winter, but only needs to be placed under the eaves facing south. Don't prune after blooming in October so as not to sprout new buds. Stop applying nitrogen fertilizer, and apply phosphorus and potassium fertilizer to make the branches strong and full, so as to enhance cold tolerance. Do not lose water when freezing to prevent death from dry freezing.

2. Generally, when the new shoot grows to 15-20 cm, cut off the top 3 cm or so to make the lateral bud germinate. When the lateral branch grows to a certain length, it will continue to pick the heart until it reaches the required number of branches.

3. It is easy to dry and lose nutrients on the potted rose flowerpot, so the cattle should be watered and fertilized in time during the growing period. It should be watered once every two or three days in spring, and then watered once a day with the rise of temperature, and should be properly watered every day in hot summer. Of course, do not make the basin stagnant water, should pay attention to drainage after heavy rain, otherwise, long-term stagnant water will cause root rot.

4. Rose flowers in the pot should be carried out before sprouting in early spring, using rotten sesame sauce dregs and horseshoe slices as base fertilizer, put ten balls of seedlings in the center of the basin, add soil around to 2cm and 3cm away from the basin, press the officers and soldiers, pour water thoroughly, place in a cool place, and move away from the sunny place after a week.

The florescence of Chinese rose

The flowering period of rose is longer, and it blossoms continuously from March to October, with delicate and colorful colors and fragrance.

Rose culture technology should be relatively simple, after all, rose is a very high survival rate of a flower, the adaptability to the environment is also very strong. However, to grow a very perfect rose, the accurate grasp of planting technology is still the grower's most authoritative rely on.
