The beginning of summer — excellent conditions for succession sowing, maintaining crops, and sowing winter brassicas for autumn and beyond.
Plan every month with the UK vegetable planting calendar.
Sow Outdoors
French beans, runner beans, beetroot, carrots, courgettes (last chance), cucumber (outdoors), kale, chard, lettuce, salad leaves, spring onions, radishes, swede

Courgettes, squash, pumpkins, runner beans, French beans, outdoor tomatoes, sweetcorn, celery, celeriac, outdoor cucumbers, leeks
Harvest Now
Broad beans, peas, lettuce, radishes, spring onions, first early potatoes, asparagus (final), rhubarb, strawberries, garlic (from mid-June)
What to Sow in June
French Beans and Runner Beans (Outdoors)
June is the last realistic month for sowing French beans and runner beans outdoors. Sow French beans 5cm deep, 10cm apart; runner beans at the base of their supports, 15cm apart. Both need soil temperatures of at least 12°C. Crops sown in June will be harvested in August and September.
Winter Brassicas — Kale and Winter Cabbage
June is the main month for sowing kale, winter cabbage, and swede for autumn and winter harvests. Sow kale in modules or a seedbed; transplant to final positions in July. Direct sow swede 1cm deep, thinning to 23cm apart — swede needs a long season and must go in by mid-June for good-sized roots. See our when to plant kale UK guide.
Beetroot and Carrots (Last Succession)
June is a good month for a final succession sowing of beetroot and carrots for autumn harvests. Beetroot sown in June will be ready from September. Carrots sown in June provide roots from October, which can be left in the ground through early winter. Avoid sowing carrots after mid-June in northern areas as they may not have enough time to develop.
What to Plant Out in June
Outdoor Tomatoes
Outdoor tomatoes should be planted out in early June in the south once all frost risk has passed. Choose a sheltered, south-facing position and stake plants immediately at planting. In northern England and Scotland, plant in early June and protect with fleece for the first two weeks. Outdoor tomatoes need a warm summer to ripen well — choose early-maturing varieties.
Sweetcorn
Plant sweetcorn out in early June once soil temperature reaches 10°C. Plant in blocks, not rows — minimum 4×4 plants for reliable wind pollination. Space plants 45cm apart in all directions. Water consistently once tassels appear.
What to Harvest in June
- First early potatoes — lift once plants flower; test by uncovering one plant first
- Broad beans — harvest when pods are 7–10cm long and beans visible through the pod
- Peas — pick every 2–3 days once pods fill; leaving ripe pods on the vine reduces production
- Garlic — from mid-June, when lower leaves yellow; lift with a fork on a dry day
- Strawberries — peak season; harvest daily when fully red

Vegetables to sow outdoors in June
Sow French beans, runner beans, beetroot, carrots, lettuce, radishes, spring onions, spinach, chard, courgettes, pumpkins and winter brassicas. Use small repeat sowings where possible so the harvest is easier to manage and gaps do not sit empty.
Seeds to start indoors or under cover
Start winter cabbage, kale, purple sprouting broccoli, late lettuce, herbs and follow-on brassicas under cover. This is useful when outdoor conditions are too cold, too dry, too exposed or too pest-prone for reliable germination.
Vegetables to plant out
Plant out sweetcorn, tomatoes, beans, courgettes, pumpkins, squash, cucumbers, leeks and brassicas. Match the planting window to your local weather and give new plants enough water while roots establish.
What to harvest in June
Harvest early potatoes, lettuce, radishes, spring onions, peas, broad beans, spinach, herbs and strawberries. Keep notes on what performed well so next year's plan is based on your own garden rather than memory.
Jobs for the vegetable garden in June
Water consistently, support climbing crops, mulch dry beds, fill gaps after early harvests and plan late-summer sowings.
Common mistakes in June
Avoid letting containers dry out, failing to support beans and tomatoes, and forgetting to sow follow-on salad and brassica crops.
Printable monthly checklist
For June, write down four columns: sow outdoors, start under cover, plant out and harvest. Add one line for weather notes, one for bed space, and one for the next crop so the month turns into a practical plan.
