Brassica care during winter
■ A wide range of brassica crops including Brussels sprouts, winter cabbage, khol rabi, broccoli, swedes and turnips are all ready or getting ready for harvest as winter progresses.
■ Though the threat of cabbage white butterflies has subsided, there are still problems to watch out for and protect against.
■ Stake your tall brassicas, such as Brussels sprouts, so they can stand up to winter storms and wind. Tread round them after high winds to firm soil that may have lifted, and do the same after frosts, which can also raise the ground.
■ Pigeons are Enemy Number One now, so guard against them with netting. This should also help deter opportunistic deer and rabbits.
Brussels sprouts need support to help them stand up to wind
