The Summer Season
June checklist
Use our seasonal gardening checklist to stay organised and make the most of your time outdoors
Deadhead early summer bedding to keep colour coming
Prune spring‑flowering shrubs now their display has finished
Shear back hardy geraniums for a fresh flush of foliage
Stake tall perennials such as delphiniums, lupins, and hollyhocks
Plant summer vegetables like courgettes, runner beans, and salad crops
Thin developing fruit on apples and pears for better harvests
Sow biennials such as foxgloves, wallflowers, and sweet williams
Refresh containers with heat‑loving plants for instant impact
Mulch borders to conserve moisture and suppress weeds
Check for pests including aphids, lily beetles, and vine weevils
Mow with care by raising the mower height to help lawns cope with dry spells
Water wisely with deep, early‑morning watering
The Chelsea Chop
A late‑May trim keeps tall perennials compact, upright, and flowering longer.
How to do it: Cut back one‑third to one‑half of each stem. Chop the whole plant or just part of it for staggered flowering.
Plants to chop: Sedum, phlox, asters, helinium, rudbeckia, echinacea, monarda, campanula, nepeta, veronica
