Reasons why the Crape myrtle plants are not blooming

Getting less or no sunlight

The crape myrtle is growing in a spot that is not getting enough sunlight in a day. The sunlight should be reaching the crape myrtle for at least 5-7 hours in a day. The plant or trees if they are getting too much will not bloom and keep growing slowly. The trees should be planted in the garden in the center or open area. The bud will stay stunted and won’t blossom. The flowers that appear will take a lot of time to open completely.

Not getting pruned

Irregular pruning or pruning the crape myrtle plants too late can bring no blooming results. The plant will show no flowers if they are not pruned at the right time. Pruning enhances the development and growth and avoids the buds to stay stunted. The early springtime is considered to be the suitable time when the crape myrtle must be pruned. This is the time when the flowering happens already and the very beginning of the flowering time.
