One of the biggest problems I have had with growing cabbage in my garden over the years is the cabbage looper insect. These rascals can skelotonize the leaves of cabbages if left unchecked.
If you see white moths flying around the garden site, get ready to do battle with the cabbage loopers. This moth lays the eggs that hatch and become the worms or larvae that feed on the leaves. They have a never ending ending appetite for your cabbage. It’s not much fun to peel the leaves off of a harvested head of cabbage and see the worms come crawling out, either.
A really neat treatment to deal with this is Bt, Bacillus thurengensis. This product is not a pesticide, but it is a biorational product that has an organism in it that will infect the gut of the worm and yet not hurt us one iota when we consume the treated cabbage. It knocks the socks off the cabbage loopers, let me tell ya.
