I had these savoy cabbages covered with garden fleece, but not very well.
Cabbage moths got in and laid thousands of eggs that developed into cabbage worms, which I didn’t notice under the fleece.
High time to get out the BT (bacillus thuringiensis) and do some spraying. If It works the cabbages can make a comeback.
This is an old story that repeats itself every year. For many years I didn’t even try to grow brassicas, but the last few I’ve been trying many ecological methods of pest control like fleece, wire netting and BT with quite a bit of success.
good luck with that, looks like a tough problem
Yes, but there are a lot of good ones still too.
Thanks for the good luck! The bacteria do help. But are are always s few disasters too.
