Title: pruning crape myrtle (ugh, non-native)
Answered by: Guy Thompson
I love crape myrtles, but they are out of our normal expertise, being non-native. However, I know that they can be kept at a height of 15 feet by an annual pruning, since they bloom on branches grown out new each year. If the tree is only pruned every 2-3 years it begins to look quite knobby at the pruning point and is, in my opinion, ugly. So pruning every winter will retain a natural look. I would suggest planting it at least 6-8 feet from the house, as the diameter of a 15 foot tree can be almost 10 feet, as indicated in this Internet site.
