Sorry, lawn mowers, No Mow May is too important to skip this year – here's why experts are urging you not to cut your grass this month

If you haven’t followed No Mow May before, 2026 might be the year you give it a whirl – because experts are warning that leaving our grass alone this month is more important than ever.

No Mow May is exactly what it says on the tin: not mowing your lawn for the entire month, allowing pollinators free rein to enjoy the grass and wildflowers (from which they collect nectar and food). It’s Plantlife’s yearly campaign to support biodiversity in our back gardens.
