Britain has already experienced one of the hottest springs on record, and with the El Niño climate phenomenon predicted to bring more extreme weather, a lawn expert has outlined four urgent steps gardeners should take 'now' to safeguard their lawns.
Aerate Your Lawn
Creating small pockets within your lawn allows water and nutrients to penetrate deep into the grass roots, bolstering its resilience during dry periods. Chris McIlroy, lawn expert at The Grass People, said: "You don't necessarily need fancy equipment to aerate your lawn, using a pitch fork will suffice. It can prevent the lawn becoming compacted, so that water can seep through instead of just sitting on top."
Choose the Right Feed
Nourishing your lawn before the peak summer heat arrives can encourage healthy growth, though it is crucial not to apply too much. Chris added: "Too much fertiliser can do more harm than good, particularly as temperatures rise. Opt for balanced or potassium-rich feeds rather than high-nitrogen products on your lawn, which can encourage vulnerable growth. Feeding plants can also help build their resilience, too."
Raise Your Mower Blade
Grass growth is vigorous at this time of year, demanding frequent cutting to remain tidy. However, if warm conditions are on the way, allowing the grass to grow slightly longer can assist it in retaining moisture. "Letting your grass grow a little longer before a heatwave gives it a head start. Longer grass shades the soil, helping it retain moisture when it matters most. Set your mower blades to a higher setting so you're not cutting too much off," Chris explained.
Water Wisely
Establishing the correct watering routine ahead of the heat arriving can prove crucial. Chris said: "Training yourself to water at the right time before a heatwave arrives means it becomes second nature when you really need it. Avoid the middle of the day, when water is likely to evaporate before it can soak through to the grass roots. Establish a habit of watering first thing in the morning. That way, when temperatures do spike, your lawn is already used to absorbing hydration properly and won't dry out as easily. Also, install a water butt so any rainfall is captured and can be used as a resource if hosepipe bans come into force."
Chris McIlroy added: "We won't know the true impact of El Niño this summer until it's upon us. But after an unseasonably warm spring, it's sensible to predict a hot summer is to follow. Taking steps to prepare your garden now will go a long way in ensuring it stays vibrant throughout the summer."
