Whilst there's still not much to do in August, there's still a list of tasks that need to be done to keep your garden looking great into the winter.

Watering
Your main priority, this month will be watering, especially if it's hot, where you are. Be sure to water thoroughly and deeply and water in the morning or early afternoon so that the lawn has the chance to warm up before the cool evening sets in. A good way to check plants are getting enough water is to take a trowel and carefully lift the soil in your borders. The soil should be moist to about 3-4 inches deep. Don't forget to check hanging baskets and pot plants, they will suffer most from the heat.

Flowers
Make sure ant flowers still on your plants are well looked after this month. Keep removing the dead and old floweheads from the plants - this will make a big difference in the appearance of the garden.
Any perrenials which flowered in the spring will be ready to divide, this month, though ensure you do this during the coolest part of the day and water then thoroughly afterwards.
Stake tall perrenials with bamboo canes to support them.
Flowering shrubs which have finsihed flowering should be pruned back into shape.

Veggies
It's time to start planting autumn and winter vegetables. Starter onions, carrots, beets, lettuce, spinach, radishes, and winter cauliflower can be put directly into the garden early this month.
Look after your potato crop, as they can suffer badly from potato blight, this month. Consider spratying them with a chemical fungicide.
Keep harvesting small, tender courgettes, to make sre you get the ones with the best flavour.
Pick Raspberries, and gooseberries, this month, not forgetting to look after the plants. Prune traspberry stems back to soil level, and cut back the main shoots and sideshoots of gooseberries to five leaves to encourage them to produce fruiting shoots for next season.

House plants
Keep watering your houseplants and watch them for disease and bugs. If it's warm and dry, you'll need to water and mist the plants in your hoase more often.
Poinsettias and christmas plants should be brought indoors, to prepare them for flowering over the holiday. If you want the plants in bloom for the holidays they must be kept at about 65 to 70 degrees, and subjected to at least six weeks of 14 hours of total darkness per day (mid to late September). This may be accomplished by placing the potted plant in a closet or unlighted room, or by covering the plant with black cloth, black plastic over a frame or a cardboard box.The plant must then be returned to the light each day and given a minimum of 4 hours of direct sun, or 10 hours of bright light.

Other bits and bobs
Keep on top of the weeds, this month. You're aiming to get them all before they have the chance to flower and go to seed again. Otherwise, they'll be coming back for several years.
Keep the water in the bird bath clean and topped up, so that it doesn't become a harbour for mosquito larvae.
Watch out for slug and snail damage and tackle the problems as they arise.
