Answer: Glad we've been helpful in the past. You can prune your privets down now or wait until spring when new growth begins. If you prune them now they should have plenty of time to develop new growth that will harden off before cold weather sets in. As with all trees and shrubs, don't prune more than one-third of the live growth in any pruning session. If your privets need more pruning than that, do it in two sessions; one now and one in early spring.
As for digging and dividing perennials, wait until they have finished flowering for the season. Late summer or early fall (Sept. in your area) would be a good time to dig and divide them, or early spring, just as new growth begins.
Best wishes with your garden!
