  • Scotch kale

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.

Eating Kale flowers I had a period where there was not much to eat out of the garden and everything was going to seed, especially the Kale. So time to get creative... what I learnt was that the Kale flower stems, before the flowers emerge, make an excellent dish. Colourful, tasty and with such a nice texture on your plate. They are also good after the flowers emerge, but the early flower stems are best. Try it, I think you'll agree...

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.

Hi, An organic gardener told me that broken egg shells keep any crawly grub away as they do not like the sharp edges of the egg. Good way to use egg shells as well. I found it did work with cabbage, cauliflower, hope this is useful to you as well.
