how to get rid of green worms on broccoli plants
The worms travel like inch worms, "looping" their bodies as they crawl over the plants. If you see one, just squish it. They are full of green stuff! :-) Cabbage loopers have many natural enemies, including yellow jackets and various parasitic wasps. Planting companion plants which attract these enemies will help cut down on damage to cabbage and other brassica plants. Nectar producing flowering plants planted with broccoli, such as calendula, english daisies, tansy and yarrow attract many beneficial insects which will parasitize and kill the worms. You may even find a mummified worm which has become parasitized if you look closely.
