How to judge whether Ziwei is dead?

1. If it is a newly planted Lagerstroemia indica seedling, it can be judged according to whether there are new leaves growing. If new leaves grow and grow well, they will basically survive without accident. If it suddenly dries up for about a week at seedling stage or mature stage, it means that Lagerstroemia indica has withered.

2. Although Lagerstroemia indica can be cultivated and managed in a large area, it is necessary to cut off dead branches, pests and diseases in time and burn them. In order to prolong the flowering period, the branches that have blossomed should be cut off in time so as to germinate again and grow the next round of flowers. In addition, crape myrtle likes sunshine, so it must be placed in a sunny place outdoors during the growing season; Pot soil should be kept moist in spring and winter, and watered once every morning and evening in summer and autumn. In case of drought and high temperature, the daily watering frequency can be appropriately increased, and river water, well water, rainwater and tap water should be stored for 2 ~ 3 days.

3. After proper pruning, the branches of Lagerstroemia indica are stout, and the growth of new shoots is large. Therefore, after flowering, residual flowers should be cut off to prolong the flowering period, and long branches, overlapping branches, cross branches, radiation branches and diseased branches should be cut off at any time to avoid consuming nutrients. In addition, attention should be paid to the prevention and treatment of Lagerstroemia indica brown spot, Lagerstroemia indica and Lagerstroemia indica.
