Penny, I never pull stuff unless it's dead. I sometimes give them a bit of light
fertilizer to help them regain strength. Otherwise I just remove awful stuff and
wait till next year. This practice usually works, at least with basically healthy
plants which are coping with unusual conditions. Lucinda
