I am trying to find out how I can get rid of small green eating worms that are chewing all the leaves on my Columbine plant... the plant itself bloomed beautifully this summer, and the flowers have dried up and are full of seeds - however the entire plant is rapidly disappearing due to small green worms attacking every single leaf.. in one day - almost 1/4 of the leaves have disappeared. I have just watered the entire plant with a combination of dish soap and Pine sol mixture... do you have any suggestions as to how one can get rid of these worms??? thank you
