With another heatwave expected to hit the UK, garden lovers are doing all they can to protect their beloved lawns from turning brown and brittle. With more sun on the horizon and little rain in sight, grass is especially vulnerable to drying out – just as homeowners want them looking their best.
During heatwaves, it’s natural to assume more watering and frequent mowing will help. But according to experts, some of the most common garden habits could be damaging the grass. That’s why they are urging gardeners to rethink their routine before the upcoming hot spell hits.
Cheryl Harper, Managing Director of Greensleeves Lawn Care, warned: “Cutting grass too low exposes the soil to direct sunlight, drying it out fast and putting the roots under stress.”
Instead, she recommends raising the cutting height on your mower and leaving the grass slightly longer – ideally around five to seven centimetres – to help shade the soil and retain moisture.
The expert added: “Try not to trim more than a third off in one go. It’s a small change with a big payoff for keeping your grass lush when the heat is on.”
When it comes to watering, it turns out less really is more if you do it right.
“A deep, thorough soak once or twice a week is much better, helping the roots grow down into the soil where it’s cooler and damper,” Cheryl said.
She added that early morning is the best time to water, before the day’s heat causes evaporation.
And with hosepipe bans becoming more common, she also suggests investing in a water butt to stay prepared if restrictions hit.
Sharp tools are another key factor in beating the heat, with Cheryl highlighting that “blunt blades tear at the grass instead of giving it a clean cut, which can leave your lawn looking frazzled and make it more prone to disease – especially in hot weather.”
