Why you should grow kale over winter


If you’re a bit bored by cabbage for your winter garden, its ‘cousin’ kale is a great-looking, great-tasting alternative.

In Japanese gardens, kale is used as a winter ornamental due to its gorgeous looks and great frost-resistance. The prettiest pink, purple or red kale can be eaten, and it’s very good for you, and considered a ‘super food’ thanks to its high vitamin content (especially vitamin C), high calcium and other minerals, and high protein content.

Grows: anywhere, very frost-resistant, especially plain-leafed and dwarf varieties

Where: in full sun

When: autumn for late winter/spring crop, late spring for summer crop

Soil: does ok in any soil but does best in free-draining soil that was well fertilised with manure or compost the previous season

Watering: water during dry periods

Pests & diseases: slugs and snails, white butterflies, aphids

Harvest: matures 6-8 weeks after germination depending on variety, cut and come again with young leaves, gets sweeter after a frost

Uses: cut out stalks as they tend to be chewy. Excellent raw or cooked, great for stir fries, can be substituted for cabbage in any recipe. Can be frozen once blanched, but doesn’t store fresh for long periods in the fridge. When cooking, sauté or boil until bright green but not beyond or it over-cooks.

Jane’s tip: apparently, putting fresh kale leaves in the freezer overnight makes them taste sweeter.
