British gardeners have been warned not to cut the grass of their lawns for one month this spring for an important reason. May is the time when Brits are being asked to let the grass in their gardens grow without being mowed, something that might seem counterintuative for people who like to keep their outdoor space neat and tidy. However, there is an important reason to let your grass, and even weeds, grow unrestricted for some time this Spring. 

Weeds attract pollinating insects such as bees. By cutting grass, you are also cutting the weeds that grow and therefore, leaving less reason for pollinating creatures to come to your garden. Pollination is an important process for the health of a plant, helping it to grow and bloom. No Mow May is a campaign by gardening experts and nature charity Plantlife. They say that you shouldn't cut your grass in May because it is a great way to support nature in your garden. 

"Approximately 97% of flower-rich meadows have been lost since the 1930s, and with them, vital food and habitat needed by wildlife," campaingers say. 

"No lawn is too small! Even the smallest wild patch can provide vital food needed by bees and butterflies, connecting us with nature and giving nature the best start to summer."

A number of pollinators, such as three bumble bee species, have become extinct in recent years. Pollinators are vital for the growth of crops and flowers. That is why it is important to attract bees and butterflies to your garden. 

Heavy use of pesticides and herbicides also have an adverse effect on pollinator populations. So, gardeners should consider using natural alternatives to ward of pests and fertilise their plants. 

When it comes to letting the grass in your garden grow for the month of May, there are a number of weeds that attract pollinators such as bees. Examples include dandelions, clovers, ground ivy and purple dead nettle. These weeds will be able to thrives if they are left to grow for the four weeks of May this year. 

Plantlife's senior ecological advisor Sarah Shuttleworth said: "Swerving mowing in May doesn’t only boost Spring wild flowers, it also allows people a little extra time to enjoy our glorious green spaces and connect with nature.

"This reclaimed time can be used to enjoy and explore wildlife friendly activities – like building a bug hotel, installing a wildlife pond or simply admiring the beauty of garden wildlife. From finches feeding on dandelion clocks to slow worms slithering in the sun there’s so much to marvel at in wilder gardens."
