December is the garden's quietest month — and that is exactly its gift. Growth has stopped, the harvest is mostly in, and the jobs left are gentle ones: gathering winter crops, protecting what remains, and planning next year's garden from the warmth of indoors. There is no rush in December, which makes it the perfect time to do things properly.
Here is exactly what to do this December in Central and Western Europe, whether you have an allotment or a few pots. Published in late October so you can plan ahead — work through it in any order, at whatever pace the short days allow.
| Job | Why now | How |
|---|---|---|
| Harvest leeks, kale & winter salads | They're at their sweetest after frost | Pick as needed; leave the rest standing |
| Protect from hard frost | The coldest weeks are coming | Fleece over tender crops; insulate pots and taps |
| Order seeds | Best choice before sell-outs | Order now from catalogues; list from this year's notes |
| Plan next year's beds | Fresh memories, quiet evenings | Sketch rotations; set one improvement goal |
| Maintain tools & structures | Nothing else needs doing | Finish tool servicing; repair sheds, fences, raised beds |
| Feed the birds | They repay you all year | Feeders up; unfrozen water out daily |
| Rest | Gardeners need winter too | Read, dream, order — spring will come |
Step 1: Harvest the winter garden — frost makes it sweeter
December's harvest is the reward for autumn's work: leeks standing tall in the frost, kale sweeter with every cold snap, winter salads under cloches, Brussels sprouts and parsnips improving by the week. Harvest as you need — these crops store best exactly where they are, in the ground.
Dig leeks with a fork (frozen ground is the only thing that stops you — mulch thickly in late autumn to keep soil workable). Pick kale's outer leaves and leave the crown. Pull parsnips and winter carrots as wanted. There is something deeply satisfying about gathering dinner from a frosty garden in December.
Step 2: Protect against the hardest frosts
December and January bring the year's coldest nights. Tender crops still outside — winter salads, late lettuce under cover — need fleece or cloches when hard frost is forecast. Double up protection on the coldest nights; remove or ventilate on mild days so plants do not overheat or go mouldy.
Protect the infrastructure too: insulate outdoor taps (a frozen burst pipe is December's classic disaster), drain and store any remaining hoses, and check greenhouse heaters if you use them. Pots clustered against the house wall survive most winters; check their fleece wrapping after gales. See our November checklist for the full frost-protection routine.
Step 3: Order seeds — the year's most enjoyable job
December is peak seed catalogue season: every variety is in stock, and ordering now means you can sow the moment spring allows. Make your list from this year's notes — what cropped well, what failed, which tomato variety won — and add one or two new things to try. Every experienced gardener's best stories start with "I just tried it once."
Order seed potatoes too — popular varieties and blight-resistant types sell out by February. And if you are planning a new raised bed or a bigger compost setup (see our compost guide), December's quiet is the time to research and buy materials before spring demand pushes prices up.
Step 4: Plan next year's garden on paper
With the garden asleep, December evenings are for planning — and your memory of this season is still vivid. Sketch your beds: what grew where (for rotation — see our first vegetable garden guide), what worked, what the slugs destroyed, where the potatoes go next year (not where they were this year).
Set one improvement goal for next year — a raised bed, a water butt, a proper compost bin, a fruit tree. One concrete plan made in December becomes real in spring; vague spring intentions rarely do. If you are brand new to all this, winter is the perfect time to read the whole site and arrive in March knowing exactly what to do.
Step 5: Finish the maintenance jobs
December's quiet is ideal for the unglamorous jobs. Finish tool servicing if November got away from you: clean, sharpen, oil — tools maintained now last decades. Repair raised beds, fences, shed roofs and cold frames while nothing is growing around them; a wobbly bed fixed in December is ready for March sowing.
Clean greenhouse glass inside and out — winter light is precious and dirty glass wastes a shocking amount of it. Check stored potatoes, garlic and onions: remove any going soft before rot spreads, and use sprouting ones first.
Step 6: Look after the wildlife that looks after you
Winter is when the garden's helpers need you most. Put up bird feeders and keep them filled — the birds that eat your feeders in December eat your caterpillars and aphids in June. Put out unfrozen water daily; in freezing weather, water matters more than food.
Leave seed heads on perennials for birds, keep a corner wild for overwintering insects, and resist the urge to tidy everything — a slightly messy winter garden is a living one. The frogs, beetles and birds sheltering in your garden now are next year's free pest control (see our pests guide for why predators matter).
Troubleshooting: December problems
Ground frozen solid — can't harvest leeks: Wait for a thaw; leeks are unharmed by freezing in the ground. For insurance next year, mulch thickly in November to keep soil diggable longer, and lift a batch into damp sand in a shed before the deep freeze.
Winter salads rotted under cover: Too wet and airless — the classic winter-kill. Ventilate cloches on mild days, water sparingly and only in the morning, and space plants for airflow. Remove rotting leaves immediately.
Mice in the shed eating seeds: Store all seeds and harvested produce in sealed metal or thick plastic containers — one mouse destroys a seed collection in a night. Set traps; do not use poison where pets or wildlife might find it.
Greenhouse full of mould: Poor ventilation plus damp — winter's greenhouse curse. Ventilate on every mild day, water in the morning only, space plants out, and remove dead leaves promptly. A small fan on low moves air on still days.
What to do this October
Reading this in late October? December feels far away — but that is the point of publishing early. Use the remaining autumn weeks to set up your December: finish the October jobs and November jobs first, then order seeds, service tools and plan beds at a relaxed pace instead of in a December rush.
The single most valuable October action for December: mulch everything (see our mulching guide). A garden put to bed properly in October needs almost nothing in December except harvesting and dreaming.
Frequently asked questions
Is there really nothing to plant in December?
Almost nothing outdoors — but you can plant bare-root fruit trees and bushes any frost-free day, and sow microgreens and herbs on a bright windowsill indoors all winter. Garlic and onion sets can still go in during mild spells early in the month.
Should I dig over beds in December?
No — leave them mulched and let the worms work. Winter digging destroys soil structure and exposes soil life to frost. The no-dig approach (see our soil basics guide) means December is a rest month for soil too.
When should I start sowing for next year?
Not yet — resist the urge. The earliest sowings (onions, broad beans, sweet peas) start in January–February indoors. December sowing just produces leggy seedlings in poor light. Plan and order now; sow later.
How do I stop feeling guilty about doing nothing?
Rest is part of gardening. The garden is dormant, the soil is resting, and so should you. Read, plan, dream — gardeners who rest in winter start spring with energy instead of burnout. You have earned it.
