The 'No Mow May' campaign, spearheaded by the wildlife charity Plantlife, encourages gardeners across the United Kingdom to refrain from mowing their lawns during the month of May. This initiative aims to allow grasses and wildflowers to flourish, providing essential habitats and food sources for bees, butterflies, pollinators, small mammals, and other wildlife.
Growing Participation in No Mow May
A recent poll conducted by Opinion Matters among 2,001 adults in March revealed that two-thirds (66%) believe their garden can make a meaningful difference for nature. Plantlife reports that the movement is gaining momentum, with analysis of participants from last year's campaign showing that nearly a third (32%) were first-time participants. The survey also highlighted a social dimension, particularly among younger demographics: six in ten people aged 25 to 34 stated they would be more likely to join if their neighbours participated.
Nicola Hutchinson, chief executive of Plantlife, emphasised the importance of collective action: "Your garden is one of the easiest ways to help nature, providing a lifeline for wildlife – yet social pressure keeps lawns short. No Mow May is the moment to act: to come together as communities, let grass and wildflowers grow, and turn that belief into real change."
Regional Hotspots and Biodiversity Benefits
According to sign-up data from last year, Tunbridge Wells (TN postcodes) topped the list for the highest number of participants, followed by the Brighton region (BN postcodes). Plantlife has previously warned that approximately 97% of wildflower meadows have been lost in less than a century, with once-common plants like ragged robin and field scabious now classified as near threatened in England.
After No Mow May, Plantlife recommends adopting less frequent mowing throughout the summer to sustain the benefits. The Royal Horticultural Society (RHS) notes that there are over 25 million gardens in the UK, representing a significant proportion of land. Even small grassy patches, if managed properly, can deliver substantial benefits for nature, communities, and the climate.
Practical Tips for Gardeners
Plantlife advises that leaving even a few areas unmown can enhance lawn biodiversity. Gardeners can mow some patches for paths or recreation while allowing other sections to grow longer, promoting flower diversity and nectar production and creating microhabitats for various species. For those without gardens, balconies, patios, or yards can be nurtured into small havens for plants and pollinators. Local authorities and communities are also encouraged to manage green spaces in churches, schools, parks, and roadsides to foster wildflower growth.
- Avoid using herbicides, fertilisers, and moss killers, as these can harm wild plants in the lawn.
- Allow plants time to set seed before mowing.
- Remove grass cuttings after mowing to prevent nutrient build-up, which can favour aggressive grasses over wildflowers.
By participating in No Mow May, gardeners across the UK can contribute to a nationwide effort to reverse the decline of wildflower meadows and support vital pollinators and wildlife.
