There are a couple ways to get rid of the cabbage worms. The hardest is to go out ever day and pick up the leaves and squash any you see, I do this when looking at my garden each day. I also spray with BT, an organic pesticide that works great. Finally there are powders you can use, but then you can not pick them for a period of time, dont use them myself so cant tell you a lot about them.
Thanks. Some of the pesticides have such severe warnings. I’ll look up BT.
Wouldn’t diatomaceous earth work with any kind of worms?
