1. Bees love them

The most obvious benefit of keeping dandelions in your lawn is the fact that bees absolutely adore them for their nectar. There are lots of other plants that bees love, sure, but dandelions are the low-effort way to keep them happy – and they’re even more crucial at this time of the year.

‘We really need to stop treating dandelions like the enemy, especially in May,’ says Julian Palphramand, head of plants at British Garden Centres. ‘They are the first real source of food for bees coming out of winter; if you mow them all down, you're essentially taking away their nectar and summer food.

If you’re keen to go all out and turn your lawn into a haven for pollinators, Johnsons Lawn Seed's Nature’s Lawn, which you can buy at Crocus, includes slow-growing grasses and native mow-tolerant wildflowers. It’s perfect for tiding your garden over to the end of No Mow May (and beyond!).

2. They're important to other wildlife, too

Bees aren’t the only insects that love dandelions – other pollinators like butterflies benefit from them, too, so they're a crucial part of our garden ecosystems. Even birds like goldfinches enjoy snacking on the seedheads.

‘Dandelions can actually play a really valuable role in supporting garden wildlife, particularly early in the season when other food sources for pollinators are still scarce,’ explains Guy Jenkins, consumer manager at Johnsons Lawn Seed, the UK’s oldest lawn seed brand.

‘Their bright yellow flowers provide an important source of nectar and pollen for bees and other insects emerging after winter, as well as the many birds that visit our gardens.’

3. They can improve lawn health

If you’re wondering if your lawn is compacted, dandelions could be the silent rescuers your garden needs.

‘Beyond the bees, those long roots are actually doing you a favour by breaking up hard, compacted soil and bringing nutrients up to the surface,’ explains Julian.

‘They’re like a natural aerator for your lawn, and because they root so deeply, they stay green when the grass starts to turn brown in the sun. This helps keep your soil from drying out completely.’

If you suspect that your lawn is compacted, it’s wise to learn how to aerate your lawn and invest in a tool like Spear & Jackson Lawn Spike Aerator from Amazon – but dandelions are certainly a handy companion.

4. They pair well with other wildflowers

Whether you’ve planted shade-loving wildflowers for a cottage garden look or classic favourites like cornflowers this year, dandelions pair really well with naturalistic planting schemes.

‘Dandelions sit nicely alongside other wildflowers to give a garden a vibrant and whimsical style,’ says Chris McIlroy, grass expert at The Grass People.

‘Sowing a 100% wildflower mix with UK native cornfield annuals is a good idea for introducing a pop of colour, and the mix won’t need particularly good soil for the wildflowers to thrive.’

So, if you haven’t sown wildflower seeds already and want to make your lawn as beautiful as it is wildlife-friendly, it’s worth throwing some down this May. This Wildflowers 'Ultimate Mix' Seed Scatter Pack from Thompson & Morgan is perfect for attracting bees and butterflies to your garden.

There are plenty of reasons why you should keep clover in your lawn for No Mow May, too.
