What can I plant in June?
June is a busy month: growth is fast, days are long and the garden needs regular attention. It's the moment to finish planting out tender crops, keep sowing salads and manage watering so plants grow steadily through early summer.
Back to planting calendarWhat can you sow in June?
June is ideal for successional sowing and for filling gaps left by early crops. Warm soil means fast germination, but hot, dry weather can stress seedlings.
Leafy salads often do better when sown in partial shade during heatwaves. Water drills before sowing to help germination in dry spells.
Keep an eye on supports, watering and feeding - these small jobs make a big difference now.
Vegetables to sow indoors or under cover
- Late cucumbers (under cover, then plant out)
- Basil and herbs (warm windowsill)
Vegetables to sow or plant outdoors
- Lettuce, radish, pak choi (partial shade in heat)
- Beetroot (successional sow)
- French and runner beans (keep watered)
- Sweetcorn (sow before mid-June)
- Outdoor cucumbers (warm, sheltered spot)
Tip: Water deeply, then mulch. Shallow daily watering encourages shallow roots and makes plants less resilient.
Tips & common mistakes
June gardening tips and common mistakes
June problems are usually about water and growth rate. Keeping conditions steady helps plants crop well through summer.
Letting seedlings dry out
Young plants have small roots and can wilt quickly. Check moisture often, especially in containers.
Inconsistent watering of tomatoes
Erratic watering can lead to blossom end rot and split fruit. Water regularly and mulch to stabilise soil moisture.
Forgetting to feed fruiting crops
Tomatoes, cucumbers and courgettes respond well to regular feeding once flowering starts.
Skipping supports and ties
Beans and cordon tomatoes can snap in wind. Tie in regularly and keep supports secure.
Letting weeds steal moisture
Hoe in dry weather so weeds dry out. Weeds compete strongly in early summer.
