How to Protect Your Garden from the Summer Heat


After the weekend’s sunny performance, it is important that we begin the preparations for protecting our gardens from the summer heat. Knowing what to do to ensure your garden doesn’t dehydrate during a heat wave can be the difference between a stunning summer haven, and a pile of wilted leaves. There are a multitude of tasks you can carry out to make sure that your garden is protected from the sun; take a look at our tips below for some great advice.


Use Reflective Mulch

The first line of defence against hot weather is applying a layer of mulch around your plants. This would preferably be reflective, such as dried grass clippings. Applying mulch protects your topsoil from direct sun exposure, keeping it moist and workable.


There are different mulch materials available which can be used by gardeners. During the hot summer we’d recommend lighter coloured mulches, like dried grass clippings as previously mentioned, as they reflect the sun’s heat more effectively than darker mulches.


For the perfect grass clippings, mow your lawn and leave the cuttings on your garden for a few days. Once they have turned a light brown, rake them up and spread them around your plants and flowers.


Water Early

During the summer months, the top layer of soil in your garden can get dry and dehydrated quickly. In order to make the most of your watering, be sure to water your plants and turf early in the morning. This optimises the amount of time they have to absorb the liquid before it gets warm enough to evaporate your efforts.


Watering in the morning also prevents heat scald, which can damage leaves that are watered whilst the sun is directly overhead. During a heat wave, seed and nursery beds may need a second watering later in the day.


Keep Grass Long

It makes sense that the taller your grass stands, the longer its shadow. This added shading can benefit your soil by helping it to retain moisture. A minimum depth for getting shade benefit is 3 inches, although some gardeners set their lawnmowers as high as 6 inches during the high summer.


Avoid applying fertilisers to your lawn during a heat wave, as your lawns ability to absorb nutrients is diminished. Waiting until the weather cools will be more effective.
