I have a herb garden and because I'm new with it, I know nothing about winterizing it. I've been covering the plants at night now but they aren't looking so good in the morning when I take the cover off. A co-worker tried to tell me to bring the plants in before we were interupted. Now I'm confused. Do I dig up the plants and bring them inside? Or just clip them and dry the herbs? Any help would be so greatly appreciated.
