I keep my brassicas covered as long as possible with enviromesh. When the cabbages have reached a good size or they get to big I uncover them. This year they have been caterpillar free but I'm not entirely sure it's just due to covers as there were pleanty of cabbage whites about & some inside the mesh, so predators must have helped. My favorite cabbage is January King but it's years since I got them to last stand till January & this year they have been ready for a month already & some have split. Timing is critical but I think the mesh will have brought them forward too.
