1. water: roses are drought-tolerant and waterlogged-afraid plants, and xerophytes are almost all waterlogged-afraid plants. If it is potted, it should be cultivated in unglazed pottery pots, and the principle of "don't water it, water it thoroughly" should be strictly grasped. If roses are often watered (especially in rainy days with high humidity and low evaporation), the roots of roses will be soaked like pickles (which is essentially different from the principle of hydroponics) and die.
2, fertilization: any plant only likes light fertilization, such as applying thick fertilizer (especially chemical fertilizer) will lead to local root rot and death. According to the size of plants and pots, apply 20-40 compound fertilizers (or nitrogen fertilizers) evenly on the pot edge of 1- 1.5 months, or water 1-2 times a month with light water and fully fermented rice washing water. As long as the leaves are green and the flowers are bright, there is no need to fertilize.
3. Lighting: When planting plants indoors, it is not advisable to put them in a hall with insufficient light for a long time, or carry them to a sunny place regularly to supplement the lighting. Without photosynthesis, plants will stop producing nutrients necessary for growth, lose the physiological cycle of water and nutrients (optical pump), and appear yellow leaves, rotten leaves and rotten roots until they die.
4. Soil: Roses have no strict requirements on soil. For indoor cultivation, select old soil with certain humus soil. Ideal soil for growing roses; Take looseness, fertility and humidity as the elements, and add some organic matter in order to loosen; Such as compost, humus, snake sawdust, coarse rice bran, etc.
5, pest control: roses are prone to aphids, powdery mildew and other leaf-eating pests, general pesticides (several alternate use to prevent pests from producing drug resistance) can be killed. Frequent rain leads to high air humidity, and leaves are prone to white mold, which can be controlled by pesticides specifically for white mold. Aphids infected with potted rose can be killed by dipping cotton swabs in white wine with a temperature of more than 50 degrees for many times (aphids will fall into the pot soil and escape) (pesticides should not be used indoors).
6. Pruning and pruning: the dormant period of roses in winter and the poor flowering period in summer; Pruning can promote the development of branches and ventilation of plants, control tree types and adjust flowering period. Pruning potted roses should not only dwarf the tree shape as much as possible, but also remove too many buds to avoid consuming too much nutrients.
