A vegetable garden is never finished — it just changes jobs with the seasons. Spring is for sowing and planting, summer is for watering, feeding and harvesting, autumn is for clearing, soil care and late sowings, and winter is for protection and planning. Gardeners who work with the seasons, rather than against them, get more food from the same beds with less struggle, because each task is done when the plants and the soil are ready for it.
This guide walks through the year for the vegetable garden, season by season, with the jobs that matter most in each. The exact dates depend on your climate — a spring sowing in a mild coastal garden may be a month earlier than the same sowing inland — so use your local frost dates and check your local extension service for the calendar that fits your area. Our frost date calculator and the zone pages, such as zone 5 tomatoes and zone 7 tomatoes, will help you pin the dates down.
Spring: sowing, planting and waking the beds
Spring starts when the soil can be worked — not when the calendar says so. If the soil sticks to your boots and forms a wet ball in your hand, it is still too wet to dig, and working it will damage its structure. When it crumbles, fork in compost, rake the beds level, and start sowing the hardy crops: peas, spinach, lettuce, radishes, carrots and onions. A few weeks before the last frost, start tomatoes, peppers, eggplant and cucumbers indoors, and harden them off before planting out after the frost has passed.
Spring is also the season for the jobs that set up the whole year. Repair beds and paths, clean and sharpen tools, and check your seed stock — old seed germinates poorly, so test a few seeds on damp paper before sowing a whole row. Put supports in place before the plants need them: bean poles, pea sticks and tomato stakes are far easier to install before the plants are growing than after. Watch for slugs, which are at their worst in damp spring weather — our guide to slugs and snails control covers the options. And sow little and often: a small sowing of lettuce or radishes every two weeks gives a steady supply, while one big sowing gives a glut followed by nothing.
Summer: watering, feeding and harvesting
Summer is the busiest season, and water is the main job. Most vegetables need steady, deep watering — a good soak that reaches the roots, rather than a daily sprinkle that wets only the surface. Water in the morning so the leaves dry quickly, and mulch thickly to hold the moisture in: our guide to mulching vegetables explains which mulches to use. Tomatoes, cucumbers and zucchini are the thirstiest crops, and uneven watering is the main cause of blossom end rot on tomatoes, so keep their water as even as you can. Our watering calculator can help you work out how much each bed needs.
Feeding matters in summer too, because heavy-feeding crops such as tomatoes, cucumbers and cabbage use up the nutrients in the bed as they fruit. Feed every two to four weeks with a liquid feed or a side-dressing — see our fertilizing vegetables guide for the details. Harvest little and often: pick beans, zucchini, cucumbers and peas regularly, because picking encourages the plant to produce more, while leaving fruit to over-ripen signals the plant to stop. Check plants weekly for pests — aphids on tomatoes, cabbage white caterpillars and cucumber beetles all build up fast in warm weather — and deal with the first few before they become an infestation. Use the pest identifier helper if you are unsure what you are looking at.
Autumn: late harvests, clearing and soil care
Autumn is the season of harvest and of putting the garden to bed. Lift the last potatoes, carrots and beets, pick the last tomatoes — green tomatoes can be ripened indoors — and clear the spent plants before disease overwinters on them. Do not compost diseased material: tomato plants with blight, brassicas with clubroot, and any plant with virus symptoms should go in household waste, not the compost heap. Our guides to early blight tomatoes and late blight tomatoes explain which diseases to watch for as the season ends.
Autumn is also the best time to feed the soil. Spread compost or well-rotted manure over the cleared beds and let the worms work it in over winter — there is no need to dig it in. Sow green manures such as crimson clover or winter rye on empty beds to protect the soil and add organic matter, and plant garlic and autumn onions for next year. Sow the last cool-season crops — lettuce, spinach, radishes and kale — for autumn and winter picking, and protect them with fleece or a cloche as the nights turn cold. Our composting basics guide covers what to do with the autumn clear-out.
Winter: protection, planning and indoor jobs
Winter is the quiet season, but it is not a dead season. Hardy crops such as kale, leeks, Brussels sprouts and parsnips stand in the ground and can be picked through winter in mild climates, and they often taste sweeter after a frost. Protect them with fleece on the coldest nights, and keep picking — a plant that is picked regularly keeps producing. In cold climates, the beds may freeze solid, and the job is to protect the soil: a thick mulch of straw or leaves stops the soil from freezing and thawing repeatedly, which damages its structure, and it suppresses winter weeds.
Winter is also the planning season, and it is the best time to do the thinking that makes next year easier. Review your notes: what grew well, what failed, what you had too much of and what ran out. Plan your rotation — do not grow potatoes, tomatoes or other members of the same family in the same bed two years running, because soil-borne diseases build up. Order seeds early, while the full range is available, and check your stored seed for viability. Clean, oil and sharpen tools, repair cold frames and cloches, and build any new beds now, while the garden is empty. If you are unsure about rotation or variety choice for your area, check your local extension service for their recommendations.
Succession sowing through the seasons
The thread that ties the seasons together is succession sowing — sowing a little, often, rather than everything at once. Sow lettuce, radishes, spinach and peas every two weeks from spring to late summer, and you will have a steady supply instead of a glut followed by a gap. Sow a second round of green beans, cucumbers and zucchini in midsummer to replace the first plants as they tire. And use the space freed by an early crop — peas finished in June leave a bed free for leeks or autumn cabbage — so no bed stands empty for long.
Succession works best when you keep notes. Write down the sowing date, the variety, and when the crop was ready, and next year you will know exactly when to sow for a continuous harvest. The harvest date calculator can help you work backwards from the date you want to pick. And remember that succession sowing is also insurance: if a late frost kills the first sowing of beans, or slugs eat the first lettuce, the next sowing is already on its way.
Common mistakes
The most common seasonal mistake is doing everything at once in spring — sowing all the lettuce, all the beans and all the zucchini in one weekend, and then having a glut in July and nothing in September. The second is neglecting summer watering, especially for tomatoes and cucumbers, which need steady moisture to fruit well. The third is leaving spent plants standing through autumn, so diseases overwinter and slugs have somewhere to hide. The fourth is leaving beds bare all winter, so rain washes nutrients away and the soil structure suffers — a mulch or a green manure costs little and saves a lot. And the fifth is skipping the planning: growing the same crop in the same bed year after year, and wondering why the yields fall and the diseases rise.
| Season | Main jobs | Key crops |

| Summer | Deep watering, feeding, regular harvesting, pest checks | Tomatoes, cucumbers, zucchini, beans, peppers |
| Autumn | Final harvests, clearing, compost on beds, green manures | Garlic, autumn onions, kale, spinach, leeks |
| Winter | Protect hardy crops, mulch bare beds, plan rotation, order seed | Kale, leeks, Brussels sprouts, parsnips |
Frequently asked questions
What should I do in the vegetable garden in spring?
Sow hardy crops such as peas, spinach, lettuce and radishes as soon as the soil can be worked, start tomatoes and peppers indoors a few weeks before the last frost, fork in compost, put supports in place early, and sow little and often rather than everything at once.
How often should I water vegetables in summer?
Water deeply and less often, so the moisture reaches the roots, rather than sprinkling daily. Water in the morning, mulch thickly to hold moisture in, and keep watering as even as you can — uneven watering causes blossom end rot on tomatoes.
What do I do with the vegetable garden in autumn?
Harvest the last crops, clear spent plants and dispose of diseased material in household waste rather than compost, spread compost or manure on the beds, sow green manures on empty beds, and plant garlic and autumn onions for next year.
Can I grow vegetables in winter?
In mild climates, hardy crops such as kale, leeks, Brussels sprouts and parsnips stand through winter and often taste sweeter after frost. In cold climates, protect beds with mulch and use a cold frame or greenhouse, and use winter for planning, rotation and tool care.
How do I avoid gluts and gaps in the harvest?
Sow little and often — a small sowing of lettuce, radishes, spinach and peas every two weeks — and sow a second round of beans, cucumbers and zucchini in midsummer. Replant beds as soon as an early crop finishes.
