Hi woodypecks,
I lost all my greens to the cabbage white caterpillar last year. My own fault, too slow getting the net out of the shed. Saying that i have never seen so many caterpillars as i did last summer. I spent ages during the day trying to pick them off, only to return in the morning and find everything covered in them. They destroyed cabbages, kale, sprouts, in fact if it was green it was gone. Wont make the same mistake this year. As soon as the greens are planted out they are getting covered with scaffold net.
