Crepe myrtle not blooming due to crowded branches
If you have an older crepe myrtle that doesn’t bloom the way you think it should, wait until after crepe myrtle bloom time and encourage the crepe myrtle bloom by pruning it carefully.
If you trim away any of the dead branches that are inside the tree, this allows more sunshine and air to reach the tree. Further, don’t just hack away at the tree. Make sure to enhance the look of the tree carefully.
