Black radish seeds — bold winter roots with real bite

Black radish is the big, peppery winter radish with rough black skin and crisp white flesh — a traditional storing root with far more punch than the little salad kind. It's part of our broader radish family within the root vegetable range. New to root crops? Our vegetable growing guide covers the basics.

Unlike summer radishes, black radish is sown in summer for autumn and winter use — the calendar shows the timing.

Choosing the right type

Most black radishes are round (Black Spanish Round) or longer and tapered (Black Spanish Long). Both have the same dramatic dark skin and hot, dense white flesh that grates into winter salads and slaws, roasts well, and stores for months in a cool place. Long types need deeper, looser soil to size up well.

Growing black radish from seed

Black radish is a direct-sown root — like carrots, it dislikes transplanting. Sow into deep, stone-free soil from midsummer, thin the seedlings generously so the roots have room to swell, and keep them watered to avoid woodiness and excess heat. Lift before hard frosts and store the roots in boxes of sand or in a cool shed.

Steady, unchecked growth gives the crispest roots, so don't let the soil dry out in late summer.

How is black radish different from salad radish?
Black radish is a large winter type with tough black skin, dense white flesh and a much hotter, more pungent flavour. It is grown for autumn, winter and storage use rather than quick summer salads. When should I sow black radish?
Sow from midsummer onwards so the roots mature in autumn. Sown too early in spring it tends to bolt instead of forming a good root. Can I store black radish over winter?
Yes — that is its great strength. Lift before hard frosts and keep the roots in boxes of damp sand or in a cool, frost-free shed for months. Why are my roots woody or too hot?
Usually from a check in growth or dry soil. Thin the seedlings well, keep them evenly watered, and harvest before the roots get over-mature.
