Growing your own vegetables in the UK is possible all year round with the right planning. By understanding what to plant each month, how to care for crops as they grow, and when to harvest, you can enjoy a steady supply of fresh produce from your garden or allotment. Izzy and I enjoyed growing salads and vegetables last year. At the moment it’s still too cold and wet to get outside in the garden (yes, I admit ‘Im a fairweather gardener!), so instead we’re thinking about what we want to grow (and eat!) this year. I always wish I’d grown pumpkins when it comes to October, but forget to plant them in the Spring. This month-by-month guide is tailored to the UK climate and works for both beginners and experienced growers.
January
What to plant
January is a quiet month, but you can start sowing onions, leeks and celery indoors or in a heated greenhouse. Broad beans can be sown outdoors in milder areas if the ground is not frozen.
How to care
Protect outdoor soil with fleece or cloches and keep indoor seedlings warm with good light. Avoid overwatering, as growth is slow at this time of year.
When to harvest
Winter crops such as leeks, parsnips, Brussels sprouts and kale can still be harvested from the garden.
February
What to plant
Sow tomatoes, peppers and aubergines indoors. You can also sow early peas, lettuce and spinach under cover. Shallots and onion sets can be planted outdoors in milder regions.
How to care
Provide plenty of light for seedlings and keep compost moist but not wet. Ventilate greenhouses on sunny days to prevent disease.
When to harvest
Continue harvesting overwintered vegetables including cabbage, kale and leeks.
March
What to plant
This is the start of the main growing season. Sow carrots, beetroot, spinach, radishes, peas and broad beans outdoors. Potatoes can be planted towards the end of the month in warmer areas.
How to care
Prepare soil by removing weeds and adding compost. Protect young seedlings from frost with fleece.
When to harvest
Early spring greens, overwintered broccoli and the last of winter root vegetables can be harvested.
April
What to plant
Sow lettuce, spring onions, beetroot, chard, pumpkins and herbs outdoors. Plant maincrop potatoes and start sowing courgettes and squash indoors.
How to care
Thin seedlings to avoid overcrowding. Water regularly, especially in dry spells, and watch for pests such as slugs.
When to harvest
Early salads, spinach and rhubarb are ready to pick.
May
What to plant
Sow French beans, runner beans, sweetcorn, carrots and beetroot outdoors. Transplant tomatoes, courgettes, pumpkins and squash after the risk of frost has passed.

December is mainly for planning, but you can force chicory or rhubarb indoors.
How to care
Protect crops from frost and snow. Clean tools and plan next year’s crop rotation.
When to harvest

With thoughtful planning and regular care, you can grow vegetables throughout the year in the UK. By sowing little and often and choosing crops suited to each season, your garden can remain productive in every month.
If you’re a beginner, keep it simple, just choose a couple of simple vegetables to grow and eat- for example by growing salad leaves, a tomato plant and cucumber, you’re creating a home grown salad. Add extras like spring onions and radishes, and then more fruit and vegetables when you feel more confident.
