How high does crape myrtle usually stay when pruning?

When pruning Lagerstroemia indica, it is generally necessary to keep the trunk of 80- 100cm, and the strong seedlings can be slightly higher. When pruning the main branch, keep it about 20-30cm, which will form a basic skeleton. When the shrubs are dry in winter, they should keep a distance of 50-60 cm from the ground.
