What should I be doing in the garden this month?

It depends on the month, but the rhythm is: sow indoors in late winter, sow and plant outdoors in spring, water, feed and harvest through summer, and clear, store and plan in autumn and winter. Use the monthly guides for the detail.

When is the last frost in the UK?

In most of the UK the last frost falls in late May, later in Scotland and the north. Tender crops like tomatoes and courgettes should only go outside once it has passed.

What is the busiest month for sowing?

March and April are the busiest sowing months, when both indoor and outdoor sowing get fully under way.

The short version

The whole year turns on the last spring frost — late May in most of the UK, later in Scotland and the north, a touch earlier in the mild south-west.
Winter is for planning — order seeds, plan beds, improve soil, force rhubarb, and start the toughest crops indoors at the very end.
Spring is for sowing — hardy crops go straight outside from March; tender crops like tomatoes and courgettes start under cover and only go out after the frost, once hardened off.
Summer is for tending and picking — water (especially pots), feed hungry crops weekly, and harvest beans and courgettes every couple of days to keep them cropping.
Autumn is for gathering and planting ahead — bring in the main harvest, then plant garlic, autumn broad beans and overwintering onions for an early start next year.
Use the two free tools — the planting calendar and the frost-date checker tailor every job to your own plot and local frost dates.

Gardening can feel overwhelming when you start, mostly because there is so much advice and no clear sense of when to do any of it. The good news is that the growing year has a steady, repeating shape, and once you understand that shape you always know roughly what to do next. This guide walks you through the whole UK gardening year, month by month, with a link to a full guide for every job.

Think of this as your home base. Each month has its own detailed page, and the two free tools at the bottom let you tailor everything to your own garden and your own local frost dates. Read it once to get the rhythm, then come back whenever you want to know what to do this month.

The shape of the UK gardening year

The whole year turns on one date: the last spring frost. In most of the UK that falls in late May, a little later in Scotland and the colder north, and a touch earlier in the mild south-west. Almost every decision in the calendar is really a question of "is this crop hardy enough to cope with frost, or do I need to wait?" Once you hold that one idea in your head, the year makes sense.

Here is the rhythm in four moves:

Winter (December to February) — plan and prepare. Little is growing, so this is your thinking and tidying season. You order seeds, plan your beds, improve the soil, force rhubarb, and make a start sowing the toughest crops indoors at the very end.
Spring (March to May) — sow and plant. This is the busy bit. Hardy seeds go straight into the ground, tender crops are started off under cover, and the whole garden wakes up. By late May the last frost has usually passed and everything can go outside.
Summer (June to August) — water, feed and harvest. Now the work shifts to keeping plants going: watering, feeding, supporting and picking. You also keep sowing quick crops to fill gaps so nothing sits empty.
Autumn (September to November) — harvest, clear and store. You bring in the main harvest, plant garlic and broad beans for next year, clear spent crops, and put the garden to bed with compost and a bit of protection.

That cycle never changes. The crops vary, the weather throws curveballs, but the shape stays the same year after year. Learn it once and you are set for life.

Cold spring? Trust the plants, not the calendar

Dates in any calendar are a guide, not a law. In a cold, late spring, hold tender crops back a week or two — soil temperature and the weather matter far more than the page of a diary. When in doubt, wait. Seedlings catch up quickly in warm soil; cold-checked plants sulk for weeks.

A quick season-by-season overview

Before we go month by month, here is the bigger picture at a glance. Each season has a job that defines it.

Winter is for planning. It is tempting to feel you should be doing something, but the best winter gardeners are the ones sitting indoors with a seed catalogue and a notebook. Decide what you want to eat, work out where it will go, and get the soil ready. A few jobs do happen outside — planting bare-root fruit, forcing rhubarb, and chitting your first early potatoes — but mostly winter is preparation.

Spring is for sowing. From March the pace picks up sharply. Hardy crops like carrots, peas and beetroot can be sown outside, while tender crops such as tomatoes and courgettes are started indoors and grown on until the frosts end. Successional sowing — sowing a little and often — starts here and keeps your harvests steady rather than feast-or-famine.

Summer is for tending and picking. By June most things are in the ground and growing fast. The skill now is keeping them happy: regular watering (especially anything in pots), feeding hungry crops like tomatoes, and harvesting often so plants keep producing. Pick beans and courgettes every couple of days or they stop cropping.

Autumn is for gathering in and looking ahead. You harvest the bulk of the year's food, but it is also a planting season in disguise — garlic, autumn-sown broad beans and overwintering onions all go in now for an early crop next year. Then you clear, compost and protect.

Month by month

Here is the heart of it. A short summary for each month, with a link to the full guide where you will find the detailed sow, plant and harvest lists.

January

The quietest month, and a good one. Order your seeds while stock is full, plan your beds, and get a head start on chitting potatoes towards the end of the month. You can force rhubarb for an early, sweet crop, and sow the very first onions and broad beans under cover. See the full list in what to plant in January.

February

The year stirs. Continue chitting early potatoes, and start sowing indoors on a warm windowsill — chillies and peppers need the long season, and the first tomatoes can go in late in the month if you have a greenhouse. Outside, prepare beds and warm the soil with cloches. The detail is in what to plant in February.

March

The busiest sowing month begins. Hardy crops can now go straight outside — carrots, parsnips, beetroot, early peas and broad beans. Indoors, keep sowing tomatoes and start leeks. Your first early potatoes can be planted out in milder areas. Everything is in what to plant in March.

April

Full spring, and the garden takes off. Sow lettuce, radishes, spinach and more carrots and beetroot outside, and start tender crops like courgettes, squash and sweetcorn indoors. Maincrop potatoes go in now. Just remember frost has not finished. See what to plant in April.

May

The pivot of the year. Frost ends in most of the UK towards the end of the month, so this is when tender plants finally move outside — but only after hardening off to toughen them up. Plant out tomatoes, courgettes and beans once the danger has passed, and keep sowing salads. The full guide is what to plant in May.

June

Peak growing. Almost everything can be outside now. Keep sowing quick crops to fill gaps, water container plants daily in warm spells, and start picking the first strawberries, early potatoes and broad beans. Stake and support tall plants before they need it. See what to plant in June.

July

The harvest builds. Pick courgettes, beans, peas and salads constantly — the more you pick, the more you get. Feed tomatoes weekly and water everything well. There is still time to sow for autumn: more salads, carrots and beetroot. The full list is in what to plant in July.

August

High summer, and the busiest harvesting month. Tomatoes, courgettes, beans and the first sweetcorn all come thick and fast. Keep watering, keep picking, and sow your winter salad leaves and oriental greens now for autumn and winter eating. Details in what to plant in August.

September

The turn towards autumn. Harvest maincrop potatoes, onions and squash, and gather the last of the summer crops before the weather cools. It is also a planting month: sow autumn broad beans and hardy salads, and plant spring cabbage. See what to plant in September.

October

Clearing and planting for next year. Lift the last roots, harvest pumpkins for Halloween, and plant garlic and overwintering onions now for a strong start next summer. Clear spent crops to the compost heap and protect tender plants. The guide is what to plant in October.

November

The garden winds down. Plant bare-root fruit bushes and trees while they are dormant, finish planting garlic, and harvest hardy winter veg like leeks, kale and parsnips — frost actually sweetens them. Tidy, mulch and protect. See what to plant in November.

December

Rest and plan. Very little needs doing outside beyond harvesting winter crops and protecting them from the worst weather. Use the quiet weeks to review what worked, order next year's seeds, and dream up next season's plot. The full guide is what to plant in December.

The whole year in one line

Plan in winter, sow in spring, water and pick in summer, gather and tidy in autumn — then start again. That is the entire calendar.

The two tools that anchor it all

A printed calendar is useful, but the UK is a long country and your garden is not the same as a garden 400 miles away. Two free tools turn this general calendar into advice for your plot.

The planting calendar lets you pick your crops and see exactly when to sow, plant and harvest each one, laid out across the year. It is the quickest way to build a personal sowing plan rather than juggling twelve separate monthly lists in your head.

The frost-date checker is the one that saves heartbreak. Enter your area and it tells you your likely last spring frost and first autumn frost — the two dates that decide when tender crops can safely go out and when the season ends. A gardener in Cornwall and one in Aberdeen are working to very different dates, and this tool makes sure you are working to yours.

Used together, these two tools and the twelve monthly guides give you a complete, personalised growing plan. Bookmark all three.

How to use this with the crop guides

This calendar tells you when. The crop guides tell you how. The two work best side by side.

When a monthly guide says "sow tomatoes indoors," click through to the full tomato growing guide for the variety advice, the right compost, and exactly how deep to sow. The same goes for potatoes, carrots, strawberries and every other crop — each has its own detailed page covering sowing, care, common problems and harvesting.

If you are growing in pots or have no garden at all, the same monthly rhythm applies, just on a smaller scale. Pair this calendar with growing food in containers and the best vegetables for containers to adapt every job to a patio, balcony or windowsill.

And if all of this is brand new, the best place to begin is how to start a vegetable garden, which walks you through choosing a spot, preparing it and getting your first crops in the ground. Come back to this calendar once you know where everything is going.

Start small, then grow

You do not need to do everything in every month. In your first year, pick three or four easy crops, follow their months here, and learn the rhythm. Add more each season. A small plot you keep on top of beats a big one that runs wild.

A couple of things worth buying once

You do not need much to follow this calendar, but a good seed collection and a year planner make the whole thing easier to keep on top of. Buy these once and they earn their keep all year — so this is the only shopping you need to do to get going.

With the rhythm in your head, the twelve monthly guides at your fingertips, and your own frost dates to hand, you have everything you need to grow food all year round. Pick this month's guide, get a few seeds in, and let the calendar do the remembering for you.
