Q.In Ohio, can I prune back my Sage, Chives, Oregano and Thyme in late March?
They survived our fairly severe winter this year in Central Ohio, because I see green underneath the woody tops. I did not get them pruned very good last year, Spring nor Fall, because I had a broken ankle and could not get into the beds very easily.
