What to do
Cut out flower stems from mock orange (philadelphus) leaving the new shoots to flower next season. Weigela needs the same treatment.
Gather herbs such as rosemary and thyme and hang them in bundles to dry in a cool airy place.
Mulch runner beans when the soil is damp, to conserve moisture. Thin kohlrabi plants so that they are not more than 15cm (6in) apart. Thin young beetroot.
Transplant purple sprouting broccoli plants, making a deep hole with a trowel and setting the young plants deep in the ground. Water them liberally into the holes, then firm down the earth around them.
Keep an eye on strawberry runners which quickly play havoc with a strawberry bed. On each plant, leave the two strongest and nip out the rest. Pick whitecurrants and redcurrants regularly.
Take cuttings of the climbing hydrangea, H. petiolaris. Use vigorous young side shoots about 8cm (3in) long and stick them into pots of a sandy compost. Firm the soil down well around them.
