Green leafy plant. Kale is a good addition or substitute for cabbage varieties. Cavalo Nero can be grown in slightly smaller spacing.

Very winter hardy. Flavour is improved by frost. Ornamental varieties are colourful, and edible. Rotate with other crops to avoid clubroot infection.

Culinary hints - cooking and eating Kale

Strong flavoured and nutritious vegetable.
Wash well and chop finely then steam.
A tomato or cheese sauce will mask the flavour if too strong.

Aphids over wintering on any curly leaved kale. Last year I grew a lot of leafy greens, the kale Nero was a great success, however the others grew really well but were infested with wooly aphids seeking shelter I assume. I'm not into chemical sprays, and getting the spray in all the curly leaves seems too time consuming, I can wash them off but it's almost pointless with the numbers per leaf. Have others found this? What can I try that's not too much of a hassle as I have a young family and don't really want to go out spraying with garlic spray for example after each time it rains.
