I'm no expert by any means, but you can't go wrong if you do the hard cut back in really early spring, before the buds break open. This spring I was experimenting and pruned off the growing tips, leaving 2 leaf pairs on the branchs. It responded well by backbudding and opening up some buds further back on the branches.
I think ima have to try the cut back next spring I appreciate the reply and info! So you cut the new growth down to 2 leaves and it’s still pushing buds? I might have to try that! Sorry I’m pretty new to bonsai and crape myrtles. Have you ever tried cutting back in the summertime? I think I read somewhere you can cut in summer?! Or maybe that’s just light pruning?
