Most years, my crapemyrtles flower in July. The actual timing of the first flower buds and flowers depends on cold the winter was. With mine, I wait until spring and new leaves to cut back the branches and tops that had winter dieback. As the days warm up and are sunny, it really pushes new growth. This year, I still don’t have flower buds but do have healthy new leaves and branches. Avoid fertilizing with a high nitrogen fertilizer. Crapemyrtles really don’t fertilizer at all. Is it in full sun? If not, that’s part of the problem. A sunny spot in the garden is best.
