When is the best time to prune them? I am in zone 8a.
Thanks


I never prune mine. In the early spring, which is around February here in Texas
8b, I remove anything which is growing inward and any branches which are smaller
than a pencil in diameter. It is not recommended they be knobbed, as you see
being done on commercial landscapes and too many homeowners crapes.
