LifestyleGardeningAlan TitchmarshTV gardening expert Alan Titchmarsh has shared advice on how often you should mow your lawn depending on the weather12:42, 22 May 2026If you think you've got lawn mowing all figured out, TV presenter and horticulturist Alan Titchmarsh reckons you might want to think again. From cutting too frequently to not nearly enough, gardeners are making a host of errors that could leave their lawns struggling when more severe weather strikes.‌Taking to TikTok, Alan's first tip is to avoid mowing too short, recommending a height of an inch in summer, or an inch and a half during particularly hot spells. He explains: "The longer the grass blades, the greener the lawn will stay. Once it gets really hot and dry and rain isn't forthcoming, the lawn will start to go brown."‌That said, if your lawn does turn brown, Alan insists there's still no need to water it, as it will bounce back swiftly once the rain returns.‌"How often should you cut your lawn?" the gardening expert continued: "At the very least once a fortnight. If you want a really thick lawn, once a week during the weather when we've got mild temperatures, sunshine and showers to keep it growing."When it gets hot and dry, cut it down to once a fortnight and leave more grass on."‌On the subject of No Mow May, Alan actually cautioned against abandoning the mower for an entire month, instead recommending that gardeners keep mowing throughout the year while leaving certain patches to grow wild for the benefit of insects.Content cannot be displayed without consentAnd for those who have already taken part in No Mow May, he suggests continuing to leave your lawn unmown throughout June as well.Article continues belowWhile overgrown grassy patches can benefit certain wildlife, Alan highlights that birds frequently depend on mown lawns to easily extract worms from the ground."Don't imagine a mowed lawn is unfriendly for wildlife, as far as the birds are concerned", he added."And provided you only use organic fertiliser in spring, like blood, bone and fish meal, no lawn weedkillers and no inorganic fertilisers."Choose Daily Mirror as a 'Preferred Source' on Google News for quick access to the news you value.‌Alan TitchmarshWeatherGardening
