These hyssops have been in my yard for now two years, and the last year, they grew tremendously, drooping and becoming really messy. I really them for the butterflies and bees they attract, but there's no way we could allow them to regain their growth from where they were this last summer. So I decided to prune them this December (very mild December, here in the Northeast). So the question is, Did I overdid it, and cut too close to the beginning of the trunk? Should I cut even further?
