Prune your Wisteria by cutting all the whippy side-shoots back to five leaves from the main stem.
Prune your apricot, cherry trees and plum trees; pruning now will avoid infection with silver leaf disease. It's also a good idea to thin out the fruit on your fruit trees to allow for better air circulation and good sized crops.
If your hanging baskets and container displays are looking tatty, give them a trim. Fertilise them to give them a boost and they will flower again within a few weeks.
Now is your last chance to feed your lawn with a high-nitrogen fertiliser to promote lush green growth. Feeding your lawn after this time will encourage too much new growth which won't harden off in time for the winter.
Harvest your garlic and onions as soon as the leaves start to yellow and die back. If the weather is sunny then bulbs can be left on the soil surface to dry, otherwise space them out in trays and leave to dry in a cool and airy place.
Trim your herbs and freeze them in ice cube trays or dry them in an airing cupboard for use later in the year. Trimming herbs now will encourage a fresh flush of growth which can be harvested again in early autumn.
Strawberry plants will send out runners at this time of year. If you'd like more strawberry plants simply peg them down and allow them to root, otherwise dispose of them before they make a tangled mess!
Divide your Bearded Iris now to allow them time to establish before winter.
If you have any gaps in your borders think about ordering perennials plants online ready for planting in the autumn.
Feed your fruit and vegetable plants regularly, especially those in containers, to ensure good cropping. July is also the time to start planting winter vegetables to allow them time to grow before the cold weather arrives.
Make sure you open the vents and doors of your greenhouse daily to improve ventilation. It also helps to damp down your greenhouse in hot weather by spraying water on the floor. The increased humidity deters red spider mites.
