1. Soil: select the soil suitable for Rose growth. Generally, loose, well drained and well aerated soil should be used.
2. Watering: don't use too much water for roses. If you water frequently, rotten roots will appear, especially in rainy days with high humidity, you must control the amount of water.
3. Fertilization: you should apply light fertilizer to it. If you apply strong fertilizer to it, it will burn the root. In about 15 days, you can use the fermented rice washing water to irrigate light water and fertilizer. In general, you don't need to apply fertilizer when the leaves are bright.
4. Light: the rose needs sufficient light for its growth. Give it more than 4 hours of light every day. If you put it in a place with poor ventilation for a long time, the leaves will turn yellow. When the temperature is low, it's better to put it at the position close to the window indoors
1. Seed propagation: put the collected seed in a bag filled with sand, heat it to 20 ℃ after one month, and then seeds can be seeded after germination. When the seedlings grow 3-5 leaflets, they can be planted separately.
2. Propagate by plants, cultivate the roots of roses, let each branch grow a new root system, cut the side branches that grow a new root when changing pots, and then a new plant will be formed.
1. Scale insect: once it appears, it is very difficult to deal with. Usually, it should be placed in a well ventilated place, and the redundant branches should be properly cut off to strengthen the ventilation. There should be no water in the basin soil. When there are spots on the branches, they should be scraped off in time. If the disease is serious, the whole branches should be cut off, and at the same time, they should be sprayed with chemicals.
2. Powdery mildew: the leaves will be raised and powdery after the disease. A layer of mould will appear on the flower buds and branches and stems when the disease is serious. To spray chemicals regularly, the branches and leaves should be cut off immediately to reduce the chance of spreading the disease.
