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.

Autumn or Fall as Americans call it is the time to plant seedlings of kale and they will grow through winter and flourish through spring however some of the plants will bolt (flower) in spring during summer when it starts to dry out you will find mealy bugs and aphids attack them but come autumn they will start to flourish again and the bugs generally go away. Where I am we get fairly cold winters (generally no snow but some fairly heavy frosts,) my kale both the tuscan black (cavalero nero) and russian red are going well at the moment. (we are just going into winter.) for you I would think august is sort of starting autumn and this is when I would be planting Kale. plenty of lime and compost on your beds is the recommendation.
