December on the Allotment: Gentle Winter Jobs for Real UK Plots

Allotment Life

The first thing you notice in December on a UK allotment is the quiet. The after-work rush has gone, the evenings have slipped away, and even the robins seem to speak in whispers rather than full-throated song. It’s easy to look at a muddy, half-finished plot and think: right, that’s it until spring.

But December doesn’t have to be a dead month. It can be a softer, slower chapter — a time for looking after your soil, tending compost, fixing small problems before they become big ones, and giving Future You a kinder spring. These aren’t the jobs that assume you have endless dry days and boundless energy. They’re tasks you can do in half an hour with a woolly hat on and a thermos by the gate.

1. Put the Plot to Bed Without Making It Bare

There’s a big difference between “putting the plot to bed” and stripping it completely. In December, the aim is to tidy things up just enough that beds aren’t chaotic — while leaving structure, roots and seedheads where they’re doing something useful.

Start with a light tidy

• Remove plants that are truly finished — yellowing, slumping, clearly past their best.
• Leave anything still feeding wildlife: teasel, sunflowers, fennel, seedheads birds are picking over.
• Snip at soil level rather than yanking roots where you can. Roots left in the ground help soil structure and become food for worms and microbes.
• Chop large sprawls of spent annuals into smaller pieces and add to the compost heap or lay as a light mulch.
• Pull up any annual weeds before they set seed: mild spells mean they’re often still doing it in December.

Add a simple winter mulch

December is a good moment to protect bare soil from winter rain, wind and compaction. On chalk-based, fast-draining soil — prone to losing moisture in summer and capping in winter — a mulch of homemade compost makes a visible difference to soil structure by spring. You don’t need to be elaborate about it:

• Plain cardboard (no plastic tape, no glossy ink) laid flat on weeded beds.
• A layer of compost or well-rotted manure on top.
• Bagged-up leaves from paths and lawns, directly on the bed or saved for leaf mould.

Even covering one or two high-use areas — the brassica bed, the spot you’ll put beans next year — is a solid December win. Don’t worry if every bed isn’t perfectly mulched.

2. Compost, Leaves and Future Soil

December is peak “future soil” season. Every bag of leaves, every bucket of wilted plants, every torn-up cardboard box is a pre-paid delivery of better beds next year. Consistent compost and mulch is what separates the best spring beds from the rest; you can see the difference in the colour and structure of the soil.

Check or start a compost bin

If you already have a heap or bin, fork it over if the weather is kind. Turning introduces air, mixes wetter and drier layers, and can give a sluggish heap new momentum. If you’ve been meaning to start composting properly, December is a very good time to set up a decent-sized compost bin. A 300L model is big enough for real-life kitchen scraps and prunings without taking over the plot, and by this time next year you’ll be spreading your own dark, crumbly compost on the beds instead of buying bags.

Bag up leaves for leaf mould

Those piles of soggy leaves on paths and grass are leaf mould in waiting. Leaf mould costs nothing at all — just leaves raked from the paths each November and December and left to rot for twelve months.

• Rake leaves into piles and scoop into old compost sacks or sturdy bin bags.
• Poke a few holes in the bags for air; drizzle the leaves with water if very dry.
• Stack in a quiet corner and leave for a year.

Next winter: crumbly, dark leaf mould for mulching fruit bushes, improving pots, or mixing into seed compost.

What to add — and what to skip

• Good December additions: chopped annual plants and prunings; vegetable peelings; shredded cardboard; egg boxes; coffee grounds.
• Keep out: cooked food, meat and dairy (attract rats); large branches (take years); thick roots of perennial weeds (dry them out or bin them).

3. What You Can Still Plant in December

There’s a lot of bravado online about winter sowing. On an exposed coastal allotment in East Sussex, December planting is a more limited affair — wind, waterlogging and hard frosts are real considerations rather than theoretical ones. Here’s what actually works:

Garlic and broad beans

Garlic is often happiest going in between October and December. I plant mine in October most years. Space the cloves well in a prepared bed, and wrap each label in a twist of wire so it doesn’t blow away. In a mild December there’s usually still time to get cloves in if you haven’t already.

Autumn-sown broad beans can go in now in milder, more sheltered areas. I sow my broad beans before Christmas. On an exposed plot, autumn-sown broad beans do best with some shelter while they establish. An alternative on very windy sites is to start them in modules in the shed and plant out a little later, since module-raised seedlings resist wind rock better than those direct-sown in December. Space both generously and use short runs rather than long rows on windy sites.

Under cover: salads and hardy greens

In a small plastic greenhouse or cold frame, even on a coastal site, you can sow:

• Hardy winter salads and oriental greens.
• Spring onions for an early crop.
• Spinach and chard for cut-and-come-again leaves through winter.

Growth is slow but steady. By late January you’ll be snipping fresh leaves rather than buying limp supermarket bags — which is one of the more satisfying feelings December sowing produces.

4. Sheds, Paths and Practical Fixes

December is quiet maintenance month — the time for small jobs that don’t look glamorous but make a huge difference to how pleasant your plot feels from January onwards.

Give your shed a winter check-up

Ten minutes checking the shed, mug of tea in hand, catches things early that would otherwise become expensive problems later. Look for:

• Drips and dark patches on the ceiling after rain — often a sign the felt is failing at the ridge or edges.
• Hinges, locks and windows for stiffness or gaps where draughts and water sneak in.
• Floor boards for any soft or sagging patches — the earlier you catch rot, the cheaper the fix.

If this is the year you finally upgrade your shed, spend a quiet evening with a tape measure and our guide to choosing the right shed size, material and base.

Sort out swampy paths

A path over wet ground turns into a mud trench by November. Improve it gradually — spare slabs first, then woodchip if your site provides it. You don’t have to redesign the whole plot:

• Lay a few spare slabs on the worst sections.
• Use woodchip if your site offers it — imperfect, but significantly better than mud.
• Mark out narrower paths if your current layout means “everywhere is path.”

One firm route from gate to shed and from shed to water butt makes winter visits notably less of an ordeal.

Look after tools now, thank yourself later

Before you lock up, one small tool task:

• Wipe mud off spades and forks; dry them so they don’t rust over winter.
• Quickly sharpen and oil secateurs.
• Hang tools rather than leaving them leaning where damp creeps in at the handle.

Protect pots and canes

• Move tender pots under cover before a frost cracks them: check corners of the plot for anything left out.
• Bundle and tie any loose canes. Left loose, they blow around and break over winter.

5. Plan Next Year with a Mug in Hand

One of the best December jobs doesn’t technically require you to be on the allotment at all. It’s the moment you gather this year’s scribbles, seed packets and half-formed ideas and sketch the bones of next year’s plan.

Make a rough bed sketch

• Draw simple rectangles for each bed — it doesn’t need to be artistic.
• Write what grew there this year; circle anything that did especially well.
• Rotate families roughly (brassicas, roots, legumes) so you’re not putting the same things in the same beds year after year.

This doesn’t lock you into a formal rotation scheme; it just gives you a calm starting point instead of making decisions on the first mild March day with a queue at the garden centre tills.

Audit your seed box

• Tip out the seed tin and sort: definitely still in date / probably fine / this is from another decade.
• Highlight what you loved this year and want to repeat.
• Make a short, focused list of gaps rather than an impulsive wishlist.

When you place an order, try to add something that genuinely suits your plot conditions. On chalk-based soil, our guide to gardening on chalk has suggestions for plants that thrive rather than merely tolerate it.

6. Tiny Rituals to Make December Visits Lovely

Finally: a few small rituals that make winter allotment visits feel like a treat rather than a punishment.

Bring a thermos and something comforting

A hot drink makes a disproportionate difference when you’re trying to persuade yourself out of the car on a grey Tuesday. A battered old chair kept just inside the shed door earns its place — for the days you need to sit and think rather than dig.

Think in 20–30 minute jobs

On dark weekdays, keep expectations genuinely low. One thing:

• Turn the compost heap once.
• Mulch just one bed.
• Stack a few bags of leaves.
• Wipe down and hang up two tools.

That’s it. You’re allowed to go home after 20–30 minutes knowing the plot is slightly better than you found it.

Notice the good bits

December on an East Sussex allotment has its own pleasures: the view across the site is suddenly open once the summer growth has gone, the light in the late afternoon can be extraordinary, and there’s always a robin following the fork. If it feels bleak, try listing three good things before you leave. It sounds small, but it anchors you to the quiet pleasures of the season.

Frequently Asked Questions

What are the main December allotment jobs in the UK?

December jobs are mostly gentle: tidying finished crops, adding a light mulch to bare beds, turning or starting a compost heap, bagging leaves for leaf mould, checking the shed and tools, and sketching next year’s plan. Even 20–30 minutes makes a meaningful difference.

Can I still plant anything in December?

In many parts of the UK you can still plant garlic and autumn-sown broad beans, as long as the soil isn’t frozen or waterlogged. Garlic usually goes in from October, and broad beans sown before Christmas do best with some shelter on an exposed plot; on very windy sites, raising them in modules and planting out a little later can help against wind rock. Under cover, hardy salads, spinach, chard and spring onions can all be sown for a slow but steady winter crop.

Should I completely clear my beds for winter?

No — there’s no need to strip beds bare. Remove plants that are truly finished, then leave useful roots and wildlife-friendly seedheads. Covering bare soil with compost, cardboard or leaf mould protects it from winter rain and helps soil structure for spring.

Is it worth starting a compost bin in December?

Yes. December is an ideal time: you have spent plants, cardboard and kitchen peelings to feed it, and a year from now you’ll have homemade compost instead of buying bags. Composting properly is the single change that makes the biggest difference to soil quality over time.

How long should I spend on the allotment in winter?

Short visits work best. December visits of 20–40 minutes are plenty — one focused task, then home for something warm. The aim is to keep the plot ticking over without it becoming a miserable obligation.
