2. Water: always keep the basin soil moist, subject to no water accumulation. Water more in spring and summer, water twice in the morning and evening when it is hot in summer, and reduce the amount of water in autumn to inhibit growth, which is conducive to wintering.
3. Fertilization: apply thick organic fertilizer once in late autumn or winter, and apply thin quick-acting fertilizer twice in spring to rainy season. Generally speaking, fertilizer and water should not be too much, otherwise it is easy to appear lush foliage and scarce flowers, so we should pay attention to properly controlling fertilization time and amount.
4. Pruning: It should be done after flowering. According to the needs of trees, cut off too long branches to promote the growth of lateral branches and increase the formation of flower buds. In addition, it can also be trimmed during eye rest, mainly to cut off the branches that affect the appearance.
5. Turning pots: It should be carried out in early spring and late autumn. It can be combined with turning pots, tidying roots, pruning branches, and placing decomposed cake fertilizer or manure at the bottom of pots as base fertilizer.
6. Pest control: There are many pests and diseases in Malus pendula, and the main diseases are scab, leaf spot and sooty blotch. It can be controlled by spraying 0.5 degree lime-sulfur mixture. Spraying 80% Jiuwei 1200 times can control aphids, scale insects, red spiders, longicorn beetles and other pests. Use Bomei 0.5 degree stone sulfur mixture and a small amount of acarbose to spray wine to control red spider.
