How to maintain and manage Lagerstroemia indica during cultivation?

Ziwei likes wet but is afraid of waterlogging, so water it properly. If you water too much, water will accumulate and the roots will rot and die. However, if water is not replenished in time, it will stop growing or dying due to lack of water, especially in flowering period, and the basin soil should not be too dry. In summer, the temperature is high and the water evaporates quickly, so it is advisable to pour enough water at night. If it is a shallow basin, you can water it once in the morning and evening to meet the needs of daytime growth. Water every other day in spring and autumn. Keep the basin soil moist in winter and water it every few days.

Apply compound fertilizer once a month during the growth period of Lagerstroemia indica seedlings to accelerate their growth. After the plant grows, apply organic fertilizer or compound fertilizer 2 ~ 3 times a year. Generally applied before and after flowering.

(2) Tree management

The flowers of Lagerstroemia indica grow at the top of the spring shoots that germinated that year, with strong germination and irregular crown, which needs reasonable pruning. Pruning is divided into winter pruning and post-flowering pruning. When pruning in winter, leave only the base 5 ~ 10 cm long, cut off the branches of the current year, and let the strong branches bloom in the second year; Cut off the residual flowers in time after flowering in summer to reduce nutrient loss and promote the germination and flowering of new branches.
