Q: How often should you prune bougainvillea in Green Valley?
A: Pruning bougainvillea should be done after flowering has ceased or as early as possible in spring after frost danger has passed. During the growing season, you can prune to direct growth as needed. How often is personal, since some folks like to let them go into wild-looking shrubs, while others prefer a tamed approach.
