January Garden Checklist: What to Do Now (Europe)

January is the garden's deepest sleep — short days, cold soil, and almost nothing growing. And that is exactly its gift: with nothing demanding your attention outdoors, January belongs to planning, ordering and dreaming. The gardeners with the best summers are usually the ones who used January well.

Here is exactly what to do this January 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 dark evenings allow.

Job	Why now	How
Order seeds	Best choice before spring sell-outs	Order from catalogues; list from last year's notes
Plan the year's beds	Fresh memories, quiet evenings	Sketch rotations; set one improvement goal
Sow onions & leeks indoors	They need the longest season	Windowsill trays in late January
Clean the greenhouse	Light is precious; pests overwinter	Wash glass, clear debris, check heaters
Service tools & structures	Nothing else needs doing	Sharpen, oil, repair beds and fences
Check stored crops	Rot spreads in store	Inspect potatoes, onions, garlic; use soft ones first
Feed the birds	The hungriest month	Keep feeders full; unfrozen water daily

Step 1: Order seeds — the year's most enjoyable job

January 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 last year's notes — what cropped well, what failed, which tomato variety won — and add one or two new things to try.

Order seed potatoes now too — popular and blight-resistant varieties sell out by February (see our blight guide for why resistance matters). And if you are planning a new raised bed, January's quiet is the time to research materials before spring demand pushes prices up.

Step 2: Plan the year's garden on paper

With the garden asleep, January evenings are for planning — and your memory of last 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 this year (not where they were last year).

Set one improvement goal — a water butt, a proper compost bin (see our compost guide), a fruit tree. One concrete plan made in January becomes real in spring; vague spring intentions rarely do. If you are brand new, winter is the perfect time to read the whole site and arrive in March knowing exactly what to do.

Step 3: Sow the first seeds — onions and leeks

Late January brings the year's first sowings: onions from seed and leeks need the longest seasons, so they go into windowsill trays now. Sow thinly into modules of multipurpose compost, keep at room temperature, and give maximum light — our seed-starting guide covers the setup, and our leggy seedlings guide the pitfalls.

Resist sowing anything else yet — tomatoes, peppers and courgettes sown in January just grow leggy in weak light. Onions and leeks are the exception because they are slow; everything tender waits until March or April.

Step 4: Clean the greenhouse and cold frames

January light is weak and precious — dirty glass wastes a shocking amount of it. Wash greenhouse glass inside and out on a mild day, clear out dead leaves and debris where pests overwinter, and scrub staging. Check heaters and insulation if you use them; a January cold snap is when failures hurt most.

Ventilate on every mild day: winter's still, damp air breeds mould (see our overwatering guide for the dampness dangers). A clean, airy greenhouse in January is ready for the seed trays of March.

Step 5: Finish the maintenance jobs

January's quiet is ideal for the unglamorous jobs. Service tools: clean, sharpen, oil — tools maintained now last decades. Repair raised beds, fences, shed roofs and cold frames while nothing grows around them; a wobbly bed fixed in January is ready for March sowing.

Check stored potatoes, garlic and onions: remove anything going soft before rot spreads, and use sprouting ones first. Chit seed potatoes (stand them eye-up in egg boxes in a cool, bright, frost-free spot) so they are ready for March planting.

Step 6: Look after wildlife — and yourself

January is the hungriest month for garden birds: keep feeders full and put out unfrozen water daily — in freezing weather, water matters more than food. The birds at your feeders now are the caterpillar-eaters of June (see our pests guide for why predators matter).

And look after the gardener too: rest is part of gardening. Read, plan, dream — the garden is dormant, the soil is resting, and so should you. Gardeners who rest in winter start spring with energy instead of burnout. Browse seed catalogues with a hot drink; it counts as gardening.

Troubleshooting: January problems

Seedlings sown too early going leggy: The classic January mistake — sowings made in excitement, stretching in weak light. See our leggy seedlings guide: give maximum light now, and re-sow later rather than nursing wrecks. Next year, wait.

Stored potatoes sprouting in the bag: Too warm — move them somewhere cooler and darker, and use sprouted ones first (they are fine to eat; just snap off the sprouts). Chitting seed potatoes is intentional; sprouting eating potatoes is just storage being too warm.

Greenhouse glass green with algae: Scrub it off — every bit of light matters in January. Improve ventilation to slow regrowth, and clear the guttering so rain washes the outside clean.

Mice in the shed eating seeds: Store all seeds in sealed metal or thick plastic containers — one mouse destroys a collection in a night. Set traps; do not use poison where pets or wildlife might find it.

What to do this October

Reading this in late October? January feels far away — but that is the point of publishing early. Use the remaining autumn weeks to set up your January: finish the October jobs, November jobs and December jobs first, then order seeds and plan beds at a relaxed pace instead of in a January rush.

The single most valuable October action for January: mulch everything (see our mulching guide). A garden put to bed properly in October needs almost nothing until spring — leaving January free for the planning that makes the whole year work.

Frequently asked questions

Is there anything to plant outdoors in January?
Almost nothing — but you can plant bare-root fruit trees and bushes on any frost-free day, and garlic can still go in during mild spells. Everything else waits.

When should I start tomatoes?
Not yet — late March is the time for Central Europe. January-sown tomatoes grow leggy in weak light and get overtaken by March sowings. Patience now means stronger plants later.

Should I dig over beds in January?
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 January is a rest month for soil too.

What is worth doing on a mild January day?
Repair jobs, greenhouse cleaning, pruning fruit trees and bushes (dormant pruning season), and a walk around the garden with a notebook — noting what needs doing beats doing it in the cold.
