Little Green catepillars
I noticed that my sweetpea plant in a pot was going brown and dying, and thought it was under watered. However on closer inspection it has lots of little green caterpillars munching my plant to death. I had the same thing on my geraniums last year and just kept picking them off. I have done this this morning on my sweetpeas but there are loads of leaves. Is there any other method of getting rid of these caterpillars.
