No-mow May: Why mowing less achieves more

No-mow May: Why mowing less achieves more

The lawn has just been mowed, the edges are neatly trimmed – for many people, this is simply part of what makes a perfect garden. Yet it is precisely this image that is deliberately challenged in May. Because during ‘Mow-Free May’, the motto is: switch off the lawnmower, switch on nature.

We at Ursa-Chemie are also making it very clear: we’re on board!

What is behind “Mowing-Free May”?

The initiative was launched by the German Horticultural Society (Deutsche Gartenbau-Gesellschaft 1822 e.V.) in collaboration with the Rhineland-Palatinate Horticultural Academy and the Baden-Württemberg Horticultural Academy – and this marks the sixth time it has been held.

The aim:
To transform millions of square metres of lawn into flowering habitats – simply by not mowing in May.

What may at first sound like a matter of convenience is, in fact, an effective contribution to nature conservation.

Why May, of all months?

May is a crucial month for many insects:

• Wild bees tend to their brood
• Bumblebee queens establish new colonies
• Butterflies lay their eggs

All these animals depend on flowers – and that is precisely what is missing from closely mown lawns.

If you let the grass grow, something amazing happens:
Within a few weeks, natural flower beds spring up, filled with dandelions, daisies, clover and more.

👉 Studies even show that:
Unmown areas are home to up to five times as many insect species.

More than just insect protection

A longer lawn has other benefits too:

• Improved microclimate: the soil stays moister and cooler
• Stronger roots: the lawn becomes more resilient to drought
• Greater biodiversity: herbs and wildflowers return

Or to put it another way:
A “green space” becomes a thriving ecosystem.

“Messy”? Or simply thinking sustainably?

In many neighbourhoods, there is still pressure to have a perfectly manicured lawn. But this is precisely where ‘Mowing-Free May’ is sparking a change in mindset:

👉 Mowing less often isn’t a sign of laziness – it’s a sign of environmental awareness.

Instead of a “manicured lawn”, the motto is: dare to be a bit wilder.

Does that really work?

A look at the UK shows that the answer is yes!

Through its ‘No Mow May’ campaign, the organisation Plantlife was able to demonstrate that: 👉 nectar production on lawns increases tenfold

This means significantly more food for:
• bees
• bumblebees
• hoverflies
• butterflies

And best of all: no need to sow new seeds.

It’s that easy to get involved

It’s really easy to get started:
1. Leave the lawnmower in the shed
2. Observe nature
3. Count flowers and insects
4. Share your results (optionally using #MähfreierMai)

There is also a hands-on activity:

“Every flower counts!”

Here, participants can:
• count flowers and insects within a one-square-metre area
• submit a photo
• take part in a nationwide competition

Prizes include seeds, gardening books and vouchers.
