To make roses lush, colorful, and leafy, it is important to pay attention to:
1. Selection of planting site. It is advisable to plant in well drained and sunny areas, and avoid planting in low-lying areas to avoid waterlogging. The soil should be loose and fertile.
2. Fertilization and watering. Before planting, it is necessary to apply decomposed organic fertilizer as the base fertilizer. Planting before sprouting. During the growth period, it is necessary to apply 1-2 times of organic liquid fertilizer mainly composed of nitrogen fertilizer, and 1 time of liquid fertilizer mainly composed of phosphorus and potassium fertilizer before flowering. After falling leaves, make a trench around the plant and apply rotting leaf fertilizer, irrigate it, and seal the soil. During the early spring bud germination period and the dry season, pay attention to watering in the hot summer to prevent the soil from becoming too dry. Watering should be done according to the dry and wet conditions of the soil.
3. Splitting. Due to the strong branching nature of roses, attention should be paid to branching, usually every 2 years, leaving 5-6 branches per plant.
4. Trimming. Pruning plants during dormancy can promote vigorous growth.
Potting aquaculture
1. Potting time. It is advisable to do so after the fallen leaves in early winter or before the sprouts in early spring.
2. Fertilization and watering. Roses prefer fertilizer. After potting, they should be fertilized with decomposed organic liquid fertilizer every 10 days. During the bud formation period, some liquid fertilizer containing phosphorus and potassium should be applied. Watering should be done according to the weather conditions. In hot summers, it is necessary to water every day. When the soil in the pot is dry, it should be watered thoroughly. After flowering, residual flowers should be promptly removed.

4. Prevention and control of pests and diseases. Please refer to the relevant information on common diseases of roses in the previous text.
The cultivation method of roses
Best growing light: Roses prefer abundant sunlight, and during the growing season, if the sunlight is less than 8 hours, they will grow excessively without flowering
The optimal growth temperature: The suitable temperature for roses is around 20-30 degrees Celsius, and they can also withstand low temperatures ranging from -25 ℃ to -30 ℃
Growth humidity requirements: Roses do not have strict requirements for air humidity, and the flowering season requires the necessary humidity in the air
Best growing soil: Roses prefer well drained, loose and fertile loam or light loam soil
The best breeding time: Roses can be planted all year round, and the best time is in spring and autumn. Generally, sowing, cutting, and grafting are carried out in early spring
Precautions for breeding roses
Spraying fertilizer:
Sprout fertilizer, mainly applied with nitrogen fertilizer; Fertilization after flowering, applied after the flowering period, mainly nitrogen fertilizer, combined with phosphorus and potassium fertilizer; Autumn basal fertilizer should be applied from the time of falling leaves to before soil freezing. Early application is advisable, with organic fertilizer as the main method. Roses prefer fertilizer, but the requirements are not strict. Depending on the growth status of the seedlings, they can be fertilized under the roots or sprayed on the leaves (such as urea, potassium dihydrogen phosphate, potassium permanganate, ferrous sulfate). Apply less and more frequently according to weather and temperature; Avoid early or excessive application, as it may cause fertilizer damage.
Watering points:
When watering roses, it is necessary to master dry watering and wet drainage. Both large and small seedlings should root first and then sprout. The physiological activities of rooting require sufficient oxygen and appropriate water, while sprouting requires sufficient water and appropriate oxygen. There should be less rain and more wind. The seedlings should be watered thoroughly, and the soil should be loosened after watering. In the future, it is necessary to control the dryness and wetness of the soil, the size of the seedlings, and the amount of rainwater for watering. In the scorching summer sun, the soil temperature is high, and watering should be done after 5 pm (the soil suddenly cools down, affecting the growth of seedlings). Heavy rainfall requires attention to drainage. Drought resistance and fear of waterlogging. Depending on the specific situation, try to reduce the frequency of watering as much as possible. In outdoor cultivation for overwintering, it is necessary to prune reasonably before hibernation and apply fertilizer once, watering thoroughly, and always pay attention to continuous good drainage, ventilation, water retention, and fertilizer retention performance.
Pruning essentials:
Every year from late April to early May, withered or diseased branches of roses are pruned and removed from the garden. Cut or excavate the 7-8-year-old old branches at a height of 20-30 centimeters from the ground, remove the old and diseased branches, and plant them separately without repeated cropping.
After the cultivation of spring seedlings, all the first and second stage flower buds should be removed (the leaf under the bud should be cut off) to save nutrients and promote branch growth. For large trees, residual flowers should be cut off, and for grafted seedlings, sprouts on the rootstock should be promptly removed. After flowering in summer and autumn, residual flowers should be cut off. Cut off excessively long branches, intersecting branches, overlapping branches, excessively long branches, and capped branches.
Disease and pest control:
The common diseases of roses are black spot and powdery mildew, which are absolutely unavoidable for general flower cultivation units and individuals. Therefore, it is important to pay attention to the prevention and management of plant diseases and pests. Continuously healthy plants themselves resist the invasion of natural cultivation techniques and bacteria. Before planting seedlings of different sizes, disinfection work should be carried out according to the actual conditions of the greenhouse and soil for sterilization and pest control. In spring, alternating use of 500-800 times of mancozeb, chlorothalonil, carbendazim, and tobuzin each (Bordeaux solution, sulfur compounds are also acceptable). It was found that red spider mites and aphids can be treated with furan emulsion, 40% dimethoate emulsion, or mixed with fungicides. Huangmei and autumn rain are the peak periods for the incidence of black spot disease, and the incidence of damp, hot, and rainy summer is also very strong. During this period, the interval between pesticide application should be shortened.
Attention for Spraying: Generally from 8am to 10am and from 4pm to 7pm. It is best to spray on a sunny day without wind.
