The timing of foliage emergence on Lagerstroemia species is closely tied to regional climate and seasonal temperature fluctuations. These deciduous trees typically initiate leaf production in late spring, following the last significant frost. The specific month when this occurs varies depending on geographic location.
Understanding the expected timeframe for leaf emergence is crucial for proper horticultural management. It informs decisions related to fertilization, pruning, and pest control. Delayed foliation can be an indicator of environmental stress or disease, prompting investigation and intervention to ensure tree health.
