About this guild
Cabbage, broccoli, kale, bok choy, tatsoi, and mustard greens are heavy feeders that attract cabbage white butterfly. Pair with dill, nasturtiums (trap crop), and aromatic herbs — avoid over-crowding brassicas which encourages clubroot.
NZ note
Plant autumn–spring in most NZ climates; net against white butterfly.
