Yan. Top dressing stopped about a week before flowering. Moderate water spray Because of the warm and humid regions of plum blossoms, plums are often sprayed on plants and buds during the bud to promote normal bud growth. During the best viewing period of plum blossoms, spray should also be given. When the potted plum blossoms are finished, it is necessary to change the pots in time and must not be delayed until the new leaves are drawn out. Otherwise, the roots lose water, and they easily die. In addition to adding enough rot-based basal fertilizer, it is also prudent to remove some of the old roots to promote the formation and growth of fibrous roots and enhance the plant's absorption function. At the same time of changing pots, the annual branchlets will be taken after flowering, leaving only about 3cm at the base of the shoots, and the rest will be cut off, which will promote sprouting of leaves and shoots. Ensure that there are more and more pregnant buds every year.
