June is one of the most active and enjoyable months in the UK garden. Everything is growing rapidly, flowers are blooming, and fruit and veg are forming. Here’s a detailed breakdown of gardening jobs for June in the UK:
🌿 General Maintenance
- Weed regularly – Warmth and moisture mean weeds flourish.
- Water efficiently – Water early morning or late evening; focus on roots, not leaves.
- Mulch beds and borders to conserve moisture and suppress weeds.
- Deadhead spent flowers to encourage repeat flowering (roses, bedding, lupins, delphiniums).
- Support tall plants – Secure floppy perennials and climbers.
🌱 Sowing and Planting
- Sow biennials for next year (e.g. foxgloves, sweet Williams, honesty).
- Succession sow salads and quick crops – lettuce, radish, beetroot, spinach.
- Plant out winter brassicas (sprouts, cabbage, kale) once hardened off.
- Sow dwarf French beans and runner beans directly outside.
🌸 Flowers and Ornamentals
- Cut back spring perennials (e.g. pulmonaria, hardy geraniums) to encourage fresh growth.
- Prune early-summer flowering shrubs after blooming (e.g. philadelphus, weigela).
- Divide clumps of spring-flowering bulbs if crowded (e.g. daffodils).
- Continue feeding flowering plants (especially containers) with liquid feed.
🍓 Fruit & Veg Garden
- Thin apples and pears if fruit set is heavy.
- Pinch out side shoots on tomatoes (cordon types).
- Harvest early crops like broad beans, peas, strawberries.
- Protect ripening fruit with netting from birds.
- Tie in canes and climbing vegetables (beans, cucumbers, peas).
- Keep an eye out for bolting in spinach and lettuce.
🌾 Lawns
- Mow regularly, but raise the height in hot, dry weather.
- Water if necessary, especially new lawns or turfed areas.
- Treat weeds and feed if not done in spring.
🐛 Pests & Diseases to Watch
- Aphids – Spray or squash; encourage beneficial insects like ladybirds.
- Black spot and mildew on roses – Remove infected leaves, use fungicide if needed.
- Slugs/snails – Especially on hostas, young veg.
- Codling moth traps – Place near apple trees.
- Net brassicas to prevent cabbage white butterflies laying eggs.
🌳 Trees & Shrubs
- Lightly prune evergreen hedges (e.g. box, yew, privet).
- Water newly planted trees and shrubs in dry spells.
- Trim topiary (e.g. box balls, cones) for neat shape.
