Quick Summary

Never miss a seasonal task again. Your complete monthly guide to sowing, pruning, feeding, and protecting your garden year-round. Your complete month-by-month calendar covering sowing, pruning, feeding, planting, and protecting tasks for UK gardens.

Introduction

Gardening is all about timing. Sow too early and frost kills seedlings. Prune at the wrong time and you lose next year's flowers. This month-by-month checklist keeps you on track throughout the year, covering everything from seed sowing and planting to pruning, feeding, and winter preparation.

January – March: Plan & Prepare

January

Order seeds and plan your layout. Clean and sharpen tools. Force rhubarb. Check stored bulbs and tubers. Begin chitting seed potatoes indoors.

February

Sow early seeds indoors (tomatoes, peppers, aubergines). Prune winter-flowering jasmine, wisteria, and late-flowering clematis. Prepare beds by forking in compost.

March

Sow hardy annuals outdoors. Plant onion sets and shallots. Start mowing lawns on a high setting. Divide perennials. Apply spring lawn feed.

April – June: Peak Growing Season

April

Sow seeds outdoors (carrots, beetroot, peas). Plant out hardened-off seedlings after last frost. Feed roses. Start regular watering routines.

May

Plant tender vegetables and bedding after last frost (mid-May in most of UK). Earth up potatoes. Stake tall perennials. Tie in climbing plants.

June

Deadhead roses and perennials. Harvest early salads, radishes, and peas. Pinch out tomato side shoots. Water containers daily in hot weather.

July – September: Harvest & Maintain

July

Main harvest period — pick courgettes, beans, berries, and salads. Continue deadheading. Water regularly, especially containers and new plantings.

August

Sow spring-flowering biennials. Take cuttings of shrubs. Order spring bulbs. Cut back faded perennials. Feed container plants.

September

Plant spring bulbs (daffodils, crocus, tulips). Overseed lawns. Divide large perennials. Harvest apples, pears, and root vegetables. Begin autumn cleanup.

October – December: Wind Down & Protect

October

Plant garlic and overwintering onions. Move tender plants indoors. Clear fallen leaves from lawns. Insulate outdoor pots. Plant bare-root trees and hedging.

November

Final lawn mow. Protect tender plants with fleece. Clean greenhouse. Rake leaves for leaf mould. Continue planting bare-root shrubs and roses.

December

Rest! Plan next year's garden. Browse seed catalogues. Check stored bulbs. Protect outdoor taps from frost. Clean and oil tools before storing.

Year-Round Tasks

✓ Add compost to beds and borders whenever you have it
✓ Keep on top of weeding — little and often beats marathon sessions
✓ Check for pests and diseases regularly
✓ Keep bird feeders topped up — birds eat garden pests
✓ Keep a garden journal to track successes and failures
✓ Water containers regularly — they dry out faster than borders

Frequently Asked Questions

When is the last frost date in the UK?

It varies by region: mid-April in southern England, late May in Scotland and northern England. Check your local frost dates before planting tender crops.

What's the most important month for gardeners?

March and September are arguably the busiest and most important months — spring preparation and autumn planting set the stage for the entire year.

Do I need to garden in winter?

Winter is mostly planning and protection time. But planting bare-root trees and shrubs in November–February gives them a head start on spring growth.
