Crepe Myrtle are also known as Lagerstroemia. They are a kind of evergreen trees or large shrubs native to Australia and Asia. They need plenty of water and fertilizer for good growth. Crepe Myrtles bloom on new growth. So the weaker branches have to be removed while pruning and 4-8 strongest branches should be left. For details see the link below:
