Not this year for us.
With a few plants, we can handpick and destroy the cabbage worms easily.
A row cover will avoid the Imported Cabbage worm butterflies to lay down theirs eggs on the leaves of the cabbage family members (broccoli, cauliflower, kale, kohlrabi, mustard, radish, turnip, etc) .
Another possibility is to do like I’m doing: grow a rosemary plant near your broccoli and cabbage plants. According to the Cornell University extension the smell of the plant will repel the cabbage moth.
I’ll let you know how that goes!
