Early spring before new growth is the best time to prune crape myrtles. Whenever you prune, you cause the tree to generate new growth. New growth that starts now will not have time to harden off before frost. See the following pubs for detailed information on pruning crape myrtles. http://www.clemson.edu/extension/hgic/plants/landscape/trees/hgic1009.html http://edis.ifas.ufl.edu/ep399
