I am sorry for this delayed reply to your gardening question. The spring rush has brought a deluge of questions and we are working hard to catch up!
The best time to prune your woody ornamental plants is in late winter prior to the onse of spring growth. Keep in mind that dogwoods and redbuds need very little if any pruning at all. If your crape myrtle is a large variety it will be very difficult and disfiguring to try and keep it that small. It is best to select a small to medium size variety that will naturally reach something close to your desired plant size.
Thanks for the question. Best wishes for a wonderful gardening season. Please stop in again soon!
