You will need to but some veggie dust or deris dust on the brassicas (cabbage, broccoli, cauliflower) during autumn to stop the white butterfly and caterpillars that follow. Once the cold winter days have set in the butterfly will disappear and you can cut back on applications.

Make sure to use a good liquid feed over the top of the plants once a fortnight to keep them growing throughout the winter months.

Get brussell sprouts in early to ensure a good crop.
