Cabbage worms - now that's just disgusting!
I've been finding cabbage worms on the brussels sprouts and cabbages for about a week now. I blast the larvae (and tiny black pellets that I think are eggs) off the plants with the hose, but notice that activity seems to be escalating.
My questions are: 1) When will the cabbage butterflies die off/stop laying their eggs? 2) Is hosing (and squishing the larvae) going to be enough to save the crop; 3) Should I try covering the plants with row cover fabric, or would it just be a wasted effort for this season?
