So my idea about using 1/2 inch bird netting as a cabbage leaf worm butterfly barrier? Failure. Above is the photographic evidence–a butterfly caught within the netting.
So two alternatives:
- Floating row cover (inconvenient and too warm for our climate)
- More biodiversity in the garden
I’m liking the biodiversity option the best. Planting a bunch of brassicas is like opening an all you can eat buffet for cabbage leaf worms. Our backyard has more biodiversity and fewer problems with pests. I used better (homemade) compost in the raised beds in the backyard, thus the soil in these beds also has greater microbial biodiversity
