Continue to harvest food crops as they ripen, including damsons and plums, maincrop potatoes, salad onions and garlic, peas and sweetcorn. If you leave garden produce in the ground, it will encourage pests and disease, which will lead to problems in later months and years. If you store fruit or vegetables, make sure that each piece is completely dry and sits sufficiently apart from the next so they do not rot.

Prune any fruit trees that are trained, and prop up any branches that have borne a heavy crop of fruit so that they can regain their strength. You should also cut raspberry canes that have fruited back to the ground, and prune blackcurrants back by one third.

You should still be liquid-feeding any container plants, and watering, particularly if you are going on holiday, but once they finish flowering and begin to enter their dormant autumn-winter state, stop. You could also give your lawn, if it is a mono-culture, a liquid feed; if you like to let it grow long and more organically, so that wild flowers develop, then a light cut is all you need to do.
Try Symbios BioBooster Organic Balanced Liquid Fertiliser, from £10.62, Symbio, 01428 685762.
