Divide congested clumps of bearded iris after flowering. Dead head bedding plants, roses and herbaceous plants to encourage more flowers.
Trim evergreen hedges, including conifers. Feed dahlias and cannas every two weeks with a high potassium fertilizer, such as tomato feed. Prune early-summer flowering shrubs, such as Philadelphus, once they have finished flowering.
Cut back flowered growth to a strong lower shoot and thin out up to a fifth of old, woody stems.
Cut back hardy geraniums and delphiniums to ground level after they have had their first flush of flowers to encourage new foliage and more flowers later in the year. Feed after cutting back.
Pinch out climbing beans when they reach the top of their supports. Water courgettes consistently so they continue to crop well and keep picking them to encourage new ones to grow. Keep tomatoes well watered to prevent blossom end rot.
Clear ponds of algae and blanket weed.
Continue mowing lawns, but raise height if we still have a drought. Newly turfed and seeded lawns need to be kept watered.
