· Hi Barbara,
Here's a list of things that may cause a Crape Myrtle to not bloom:
1- Too much shade. Crape Myrtles love strong sun exposure and heat and will not bloom in shaded areas.
2- Too much fertilizer. Over usage of liquid fertilizer such as Miracle Grow may cause the plant to grow faster and larger but can prevent blooms. Too much nitrogen could be the problem.
3- Lack of phosphorus. Phosphorus enhances root development. A better root system creates a healthier plant. A healthier plant blooms more. Try using Triple Super Phosphate or Bone Meal.
4- Pruning at the wrong time of year. If a Crape Myrtle is pruned during the month prior to blooming, the buds will be removed. No buds, no blooms.
5- Colder climates. Though some varieties of Crape Myrtle will survive in cooler climates, they won't bloom well.
Hope this helps you.
