Lawn specialist Chris McIlroy has revealed how to safeguard your garden as El Niño threatens to disrupt global weather patterns and unleash scorching summer temperatures. The UK has already endured one of the warmest springs on record, and with the climate phenomenon El Niño showing no signs of easing, experts are warning that further extreme weather is on the way.
Aerate Your Lawn
Puncturing small holes in your lawn allows water and nutrients to penetrate deep into the grass roots, boosting its ability to withstand dry periods. "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," Chris said.
Choose the Right Feed
Nourishing your lawn before the height of summer arrives can encourage healthy growth, though it's crucial not to go overboard. 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 grows vigorously at this time of year, needing frequent cutting to remain tidy. But if warmer weather is on the way, leaving your lawn a touch longer can help it retain 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
Developing the correct watering routine before the heat arrives can make a world of difference, according to Chris. He 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."
