Growing winter salad leaves
There are few quieter pleasures than picking a bowl of your own salad in December — fresh, peppery leaves gathered with cold fingers while the rest of the garden sleeps. And it's far easier than it sounds. The trick is to sow the hardy leaves in late summer, let them bulk up before the light goes, and tuck them under a little shelter to pick all winter long.

The leaves that laugh at frost
Summer salad sulks and bolts in the cold; these are the tough ones, bred or born for it. Most are mild, some are peppery, and several actually taste better for a touch of frost. Grow a mix and you'll have a proper salad — soft leaves, sharp leaves, and something with crunch — all winter.
The toughest winter leaf of all — mild, nutty rosettes that shrug off hard frost. The backbone of any winter salad.
Hardy varieties like Winter Density and Arctic King stand the cold far better than summer types. Pick leaf by leaf.
Fast, feathery and mild, with a faint mustard tang. Cut-and-come-again all winter under a cloche.
Peppery and beautiful, and the cold only sharpens the flavour. 'Green in the Snow' is as hardy as its name.
Slower and milder than summer rocket, and far less likely to bolt. A reliable cold-weather cropper.
Heart-shaped, succulent leaves that are utterly unbothered by frost — one of the most generous winter croppers there is.
Tastes just like watercress, but hardy and easy in ordinary soil. A peppery lift for winter plates.
Sow in early autumn for tender leaves that crop into winter and romp away again in spring.
A little shelter changes everything
Most of these leaves are hardy enough to survive a hard frost in the open — but surviving and being nice to eat are two different things. Winter rain, wind and slugs tatter unprotected leaves fast. A bit of cover keeps them clean, dry and worth picking, and it needn't be heated — just sheltered.
- A cloche— the simplest fix. A little tunnel or row cover keeps the rain off and a few degrees of warmth in. On Amazon →
- A cold frame— the snug spot for the best winter pickings, and brilliant for hardening off in spring too. See our cold frames & greenhouses guide.
- An unheated greenhouse or polytunnel— if you have one, winter salad is the perfect thing to fill it with once the tomatoes are done.
- A windowsill— even a few pots of cut-and-come-again leaves indoors keep a salad going when the garden is frozen solid.
Picking through the cold
Harvest cut-and-come-again: take a few outer leaves from each plant rather than cutting the whole thing, and leave the central growing point to push out more. In the depths of winter the plants barely grow, so pick lightly and spread your cutting across the whole row — treat it as a slow, steady larder rather than a single big crop, and it'll keep you in salad for months. Come the first warmth of spring, everything surges back into growth for one last generous flush before it runs to seed.
Common questions
What salad leaves can you grow in winter in the UK?
The hardy cut-and-come-again leaves: lamb's lettuce, winter lettuce, mizuna and mibuna, mustard leaves, winter rocket, claytonia, land cress and hardy spinach. Under a cloche, cold frame or greenhouse they give fresh salad right through the cold.
When should I sow winter salad leaves?
From late summer into early autumn — roughly August to early October. The plants need to do most of their growing while there's warmth and light, then sit and be picked through winter. Once midwinter's short days arrive, growth all but stops.
Do winter salad leaves need protection?
Most are genuinely hardy, but a cloche, cold frame or unheated greenhouse makes a big difference — keeping leaves clean, dry and pickable and stopping rain and slugs spoiling them. They need shelter, not heat.
How do you pick winter salad so it keeps growing?
Take a few outer leaves from each plant rather than cutting the whole thing, leaving the central growing point to push out more. Plants regrow slowly in winter, so harvest lightly and across the whole row and they'll keep giving for months.
