I have a Crape Myrtle located in Central Florida, and I have a question regarding pruning timing. The tree will be transitioning into the refinement phase of growth in some areas. In an attempt to consistently progress the tree while staying horticulturally sound, how do I dial in the timing? I only prune in an energy positive state and I look for indicators like formation of leaf cuticle, color change and growth suspension. What is throwing me off, and what I would like dial in, is new shoot lignification. I remember in the bald cypress stream, Ryan Neil, mentions the importance of lignification in new cypress shoots or color change to straw before pruning in order to create bifurcation. New Crape shoots are very soft and fleshy, long after leaf hardening and cuticle formation. Should I wait for shoot lignification, essentially lengthening each flush of growth or are the typical hardening signs enough?
Does anyone have any experience with a pinching strategy similar to maples?
