The August Garden Jobs That Keep Your Plants Alive in a Heatwave

Get the basics right this month, from how you cut the grass to who you let loose on the pests and when you reach for the watering can, and your plot can ride out the heat rather than surrender to it. The gardening tips shared by Fabulous lay out the essentials worth tackling before the summer runs out.

Stop mowing like it is spring

One of the most common August tasks is also the one people get wrong: fertilising the lawn. It should be avoided this month, because feeding the grass now tends to attract autumn pests rather than green things up. Brown grass, meanwhile, is entirely normal in hot weather and no cause for panic. The smarter move is to raise your mower blades and leave the grass longer, giving it a fighting chance of withstanding the heat and holding a little more moisture at the roots. It is a small change of habit that pays off across a parched August.

Let the ladybirds do the heavy lifting

If pests are marching across your beds, resist the urge to reach straight for chemicals and recruit some ladybirds instead. They are a gardener's best friend, quietly seeing off fruit flies, mites and scale insects without any effort on your part. The counter-intuitive trick is to leave a few aphids on your less valuable plants; that ready food supply encourages the ladybirds to settle in and stay, effectively turning a corner of your garden into its own free pest-control operation for the rest of the season.

Watering: the trickiest garden jobs under a hosepipe ban

With so much of the country under restrictions, watering has become the most delicate of the August garden jobs. The aim is to make every drop count: water at the cooler ends of the day so less is lost to evaporation, aim for the roots rather than the leaves, and prioritise pots and fresh plantings, which dry out fastest of all. A garden gasping in the heat is a reminder that you need to look after yourself too, and there are plenty of ways to beat the heat indoors while the current UK heatwave rumbles on.

None of this requires a horticulture degree or a spare afternoon, just a bit of timing and restraint. Ease off the mower, back the ladybirds and water with intent, and the garden that looked doomed at the start of the month stands a real chance of still flourishing when September arrives. In a summer defined by heat alerts and hosepipe bans, the smartest garden jobs are the ones that work with the weather instead of against it.
