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.

When do you harvest kale?

Anytime it looks good to you, start harvesting the outer leaves, they will keep growing more from the inside. I over harvest mine sometimes, just leaving a few baby leaves coming out of the top, & they still keep coming,

If you are planting now, end of Aug or early Sept. Full sun is great in 7b
