As the UK basks in a balmy heatwave this week, with scorching highs of 34C forecast to hit this weekend, gardeners are being warned not to water their lawns. The UK Health Security Agency (UKHSA) issued an amber alert for all of England on Thursday, warning that a rise of deaths among vulnerable groups is “likely” as temperatures rocket around the country.
Vanessa Cook, owner of Stillingfleet Lodge Gardens is urging gardeners to not turn on their sprinklers as the heat is at its peak as it is “completely unnecessary”. Speaking on BBC One’s Breakfast show this morning, Ms Cook lifted the lid on why watering your lawn is not recommended and how lawns survive the soaring temperatures.
She reassured homeowners that their lawns will be “lovely and green again” once the UK receives a downpour of rain.
The expert was asked how she feels driving past a house and there is a sprinkler going full force in the lawn
To which Ms Cook replied: “Don’t water your lawn! I almost stop the car and say please, don’t water your lawn, you are wasting water, it’s completely unnecessary. Lawns are wonderfully good at being hardy and surviving.
“The minute you get rain, they will be lovely and green again.”
Her warning comes not just amid heatwave conditions but also as a lack of rainfall has seen reservoir levels plunge, with Brits urged to be mindful about their water consumption.
Insufficient watering during a heatwave can be detrimental to the lawn’s health as much of the water will evaporate before it can be absorbed by the grass.
The scorching heat can also inhibit grass growth and lead to wilting. It is instead recommended to water in the early morning or late evening, when temperatures are cooler, allowing the water to soak into the soil and reach the roots more effectively.
