What to do
Germination of runner beans has been erratic, perhaps because of the dry start to the growing season this year. There is still time to sow more, if necessary, but hurry.
Sow Brompton stocks, pansies and perennials, such as alpine and Iceland poppies, outside now for flowering next year. Thin out hardy annuals sown direct in the garden.
Remove side shoots from tomato plants (except bush varieties) and keep courgettes and cucumbers well mulched.
Pot cuttings of garden pinks, about 7cm (3in) long, in a sandy mixture of soil. Firm the soil down well.
Begonias and busy lizzies are thirstier than other annuals. Give them top priority in the watering can rota. Hydrangeas need a lot of water too.
Prune early-flowering honeysuckle if it is too big for its allotted space. Cut back the shoots that have flowered, making the cut at a point where a fresh, new shoot is breaking.
