After transplanting Lagerstroemia indica from August to September, can the leaves get sunburned and live?

Ziwei should not be too high. Build a shade shed. If the shed is difficult to build, pull a sunshade net and don't see strong light for the time being. If there are many leaves, pick the withered ones and roll them away. Spray water on the leaves many times during the day. If you have time, if possible, use hanging bags to replenish water to the trees. See if the leaves can slow down. If they slow down, they will live.
