No Mow June – should you let your lawn keep growing?

The short answer is yes! If you can, letting your lawn grow into June can offer even greater benefits for wildlife.

Why extend no mow?

During May, unmown lawns allow wildflowers like daisies, clover and buttercups to bloom, offering vital nectar for early-emerging bees and other insects. But for many species, including butterflies and moths, June is a critical month for feeding and breeding. Longer grass provides shelter, while flowering plants continue to offer food.

By extending No Mow May into No Mow June, you’re not just helping pollinators, you’re supporting a wider network of wildlife that relies on undisturbed grassland.

A balanced approach

Of course, not everyone wants a completely wild lawn. If you’re concerned about the look of your garden or worried about the health of your turf, you can take a mixed approach. Try mowing some paths through the grass or cutting back a small section while leaving the rest to flourish. This keeps your lawn accessible and neat while still providing valuable habitat.

Another option is to set aside a specific area of your lawn, even just a corner, as a long-grass zone for the summer. You’ll be surprised how quickly insects, birds and small mammals make it their home.

Will it harm the grass?

Temporarily stopping mowing won’t harm most turfgrass species. In fact, giving the lawn a break from regular cuts can actually strengthen root systems and improve resilience. Just be sure to raise the mower blades when you do finally cut; a drastic short mow after weeks of growth can stress the grass.

No Mow May is a great start but No Mow June takes it further. Whether you fully commit or go halfway, allowing your lawn to grow a little longer can be a simple, effective way to support biodiversity in your own back garden.
