Can Lagerstroemia indica survive if its trunk cracks?

1. First, you can disinfect the wound with bactericide and coat the trunk with healing agent.

2. Secondly, shade properly and cut off some redundant leaves to reduce the burden of branches that cannot supply enough nutrients and water due to injury.

3. Finally, wrap the trunk tightly with a piece of cloth. After a period of time, the split wound will heal itself.
