Water
Water regularly during the growing season, especially when young, to keep the soil consistently moist but not waterlogged. Reduce watering in fall and winter as the plant enters dormancy.
Ensure good drainage to prevent root rot.

Watering, pruning, propagation, and repotting details from plant data
Water regularly during the growing season, especially when young, to keep the soil consistently moist but not waterlogged. Reduce watering in fall and winter as the plant enters dormancy.
Ensure good drainage to prevent root rot.
Prune in late winter or early spring while the plant is dormant to shape the tree and remove dead, damaged, or crossing branches. Pruning after flowering can remove next season's buds.
Pinching back new growth can encourage bushier habits.
Propagate Lagerstroemia floribunda from seeds, which require stratification, or by semi-hardwood cuttings taken in summer. Cuttings should be treated with rooting hormone and kept in a humid environment.
Layering is also an effective method.
Repot young plants every 2-3 years in early spring before new growth begins. Mature trees typically do not require frequent repotting.
Use a well-draining potting mix and a slightly larger container, ensuring not to disturb the root ball excessively.
