It’s No Mow May! This initiative was first launched by Plantlife in 2019, asking us to pause mowing our grass for just one month to help nature thrive. Behind this simple idea lies something urgent: our landscapes are losing the wildflowers and insects that keep ecosystems functioning. With 97% of flower-rich meadows lost since the 1930s, gardens now play a crucial role in providing habitat.
May is a hungry month for pollinators. Bees and butterflies are emerging from winter, but nectar sources are still scarce. When we stop mowing, native wildflowers like dandelions, clover, and birds‑foot trefoil get the chance to bloom and provide much needed food for them. These flowers aren’t ‘weeds’, they’re lifelines. In Ireland, one‑third of wild bee species are threatened with extinction, largely due to lack of food. Giving them even a small patch of unmown grass can make a measurable difference.
When you let your lawn grow:
- Pollinators find food when they need it most.
- Soil health improves, as longer grass shades and protects it.
- Birds and small mammals benefit, feeding on seeds or sheltering in taller vegetation.
- Carbon is stored below ground, thanks to deeper, stronger root systems.
- Biodiversity increases, even in tiny gardens.
Even a single square metre of unmown lawn can support dozens of flowering plants and the insects that depend on them.
Perhaps the most unexpected gift of No Mow May is how it changes us. When we stop mowing, we start noticing: tiny flowers we’ve never seen before, bees we didn’t realise lived in our gardens, the soft movement of long grass in the wind. It reconnects us with the wildness right outside our door.
In a world where environmental problems can feel overwhelming, No Mow May offers something refreshingly doable. One month. One patch of grass. One small act that, multiplied across millions of gardens, becomes a powerful gesture of hope.
