Remove large shrubs and trees that were casualties of winter water logging and summer drought. Remove stumps wherever possible, as rots could spread to other plants.
Prune wisteria and climbing shrubs such as Pyracantha after flowering, Hebes and lavenders can also be given a light prune.
Pests and Diseases
Brown patches, needle loss and sooty mould on spruce (Picea) trees are evidence of green spruce aphid damage earlier in the year.
Mid to late August is a good time of the year to apply biological controls for vine weevil. Grubs will be starting to hatch and soil temperatures are now suitable for the nematodes to be effective. Target vulnerable plants such as Rhododendron, Camellia and containerised plants including fuchsias.
Powdery mildew can be a problem in dry summers.
