1. Ignore irrigation and die from drought. The flowerpots of potted fruit trees are small in volume, and the roots of the fruit trees are shallow, and they are prone to lack of water. If you do not add water in time, the leaves will wilt and even die. Therefore, it is necessary to keep the pot soil moist and water frequently.
2. Burn to death due to excessive fertilization. Potted fruit trees should use fully decomposed organic fertilizer in a reasonable proportion, with a small amount of phosphate fertilizer (superphosphate, etc.) or no chemical fertilizer. When top dressing, too much fertilization at one time can also cause the death of fruit trees. Therefore, it is necessary to pay attention to a small amount of fertilizer several times when fertilizing, and once the fruit tree wilts, water should be quickly diluted to dilute the fertilizer.
Third, the amount of branches is small, and the fruit setting rate is low. Potted fruit trees grow in limited containers, and a large amount of water must be supplied during the first year of growth to accelerate the growth of fruit trees. In the later stage of growth, the growth of fruit trees is controlled to form flower buds. If the new shoots are small, the growth is small, and the leaf area is small in the next year, it is necessary to replace the soil, invert the pot, and repair the roots to rejuvenate and form full and full flower buds. The flower buds are full, and with artificial pollination and thinning of flowers and fruits, the fruit setting rate can be increased.
