If you have any questions before getting started, from what happens when you stop mowing, to which flowers might pop up – here’s everything you need to know to join the movement.
For the past 7 years, thousands of people have joined our No Mow May movement, choosing to give nature a boost by letting their lawns grow.
This year, it’s all about the flowers! We want as many people as possible to give power to the flowers by letting their lawns bloom throughout May and beyond.
No Mow May™ is Plantlife’s annual campaign we launched in 2018 to encourage people to manage their lawns for nature.
But No Mow May is just the beginning, it’s followed by Let it Bloom June and Mow-saic months right the way through. They’re all part of the growing No Mow Movement!
We see May as an entry point for people, whether you’re someone who has never thought beyond a neatly manicured lawn or someone who has always wanted to try gardening for nature. Our aim is simple: to get people cutting less, for longer. So, whether you join us just for May or stick with it all season, it all makes a real difference for nature.
We chose May to get started, because that’s when most of our wonderful wild plants are getting going for the season. Giving them time during this period gives them a good head start.
At this time of year, your garden can also become a haven for wildlife at a time when it is greatly needed.
We think of May as the starting point, a springing board for managing your lawn for nature year round. Sometimes it’s easier for people to start small, before committing to a bigger shift in their gardening journey. The goal is to mow less for longer.
2025 will be our 7th No Mow May! We started the Movement back in 2018 and thousands of people have joined us over the years, creating space for nature in their gardens.
Approximately 97% of flower-rich meadows have been lost since the 1930s, and with them, vital food and habitat needed by wildlife.
While this fact is alarming, joining the No Mow Movement is one way we can all help. There are more than 20 million gardens in the UK, and every patch, no matter how small, can add up to deliver huge gains for nature, people and the climate.
The good news is that everyone can take part in No Mow May! Even the smallest areas can add up to big wins for nature. So, whether you have a tiny space, a balcony or no garden at all, there’s always ways to join the movement.
You could make a mini meadow in even the smallest garden, or you could create one in a planter. Read our 6 Ways to do No Mow May Without a Lawn blog here, for more ideas.
Parks, road verges and village greens can all be turned into wild areas. Look out for your local Friends of Group to see if there’s any green spaces you could get involved in. If you’re not lucky enough to live close to an established group, why not consider starting your own community meadow? Read our guidance here for more information.
We’re glad you asked! It’s super easy to join the movement, all you need to do is sign up here, then put your feet up and let nature do the rest! And, for some top tips on taking part, read our lawn guide here.
The more people that sign up the better! We have streamlined our sign-ups so it’s quicker than not mowing your lawn! Registering helps us to keep track of the space that is being created for nature across the UK.
Plus, by joining the No Mow Movement you will also get access to exclusive tips, guides, stories and badges
How you take part in No Mow May is up to you — but if you want to give biodiversity the biggest boost, there’s a simple trick –, variety!
Keeping 2two to 3three different grass lengths throughout the summer helps maximise flower variety and the nectar they produce.
Nature will thank you! Giving your lawn a mowing break over the summer can allow time needed by wildflowers, to grow, bloom and set seed.
Wilder lawns are great for nature, for carbon storage, biodiversity and of course wildlife! From the insects and birds that can hide away in longer grasses, to the pollinators that wildflowers will feed, your lawn will be buzzing with life.
We encourage people to manage their lawns for nature all year round, and management does include mowing. We know that some people will need to mow more frequently than others – it’s all about mowing less for longer. Even cutting down to mowing once a month can boost lawn biodiversity and help pollinators.
If you are leaving your lawn for nature all summer long, we know that the grassy growth might get away from you.
But many mowers can cope with taller vegetation, especially if you mow in 2 stages:
Firstly, check your lawn for wildlife – and never mow around the edges towards the centre, this leaves no escape route for wildlife. Instead, as you mow, progress gradually towards sanctuary areas such as uncut grass strips at boundaries.
Next, set the blades as high as possible then mow strips only half as wide as the mower. This will reduce the load on the mower’s engine and make the job easier. You can then re-pass as normal with blades set lower to finish the job. Alternatively, if you have one, a strimmer can be a better way to tackle a taller sward.
Remember to remove your grass cuttings after you’ve finished strimming or mowing to prevent nutrient build-up on lawns, which can be detrimental to many wild plants.
This can depend on many of different things from how nutrient– rich your garden is, to the PH of the soil and what has seeded there naturally over time.
Common flowers you can look for include the Bird’s-foot-trefoil, Creeping Buttercup, Daisy, Dandelion, Clover, Self–heal and speedwells.
The more you let nature back into your garden, the more likely you will be to see wildflowers in the future. However, if you want to encourage more wildflowers into your lawn, there are a few things you can do.

We know it’s not practical for everyone to leave their entire lawns all summer long – that’s why we recommend a mow-saic approach!
Traditional hay meadows are cut once in the summer and then kept short by grazing until April. This is the process we are trying to replicate in our green spaces, so ideally some mowing is needed.
Keeping some areas longer and some shorter is a great way to keep your garden accessible while benefitting wildlife But really, how long you want to go is up to you!
Lawns left long between April or May until mid July followed by simply mowing regularly afterwards, will go straight back to that green carpet look for the rest of the year.
However, if you choose to leave your lawn long right the way through the summer until September, it might start to affect the look. Leaving your lawn long for longer can create some tussocky grass as well as thatch (dead grass/plant material), though this can be raked away partially.
If want to find out if you’re lucky enough to have any late blooming wildflowers in your lawn, but you don’t want to affect the look long term, you could try alternating. One year you could cut in mid-July then the next you could leave your lawn until September.
While No Mow May has clear benefits for wildlife, we understand it can raise some concerns for people too. We don’t want to shy away from the questions or worries you might have—so below, we’ve addressed some of the most common ones.
No Mow May is good for wild plants but what about other wildlife? Longer grass can make the perfect hiding place for hedgehogs and bugs to take shelter. And we know that this causes concerns about the risks that animals could face when it comes time to mow.
Our advice is to work gradually parallel to shelter (such as borders and hedges), which the wildlife can move towards. So you are moving closer to the shelter one mower’s width at a time.
Work from paths and high footfall areas towards the boundaries to allow disturbed wildlife to move towards cover gradually. Never mow from the outside inwards. Making a first pass with a high blade setting on your mower will help to flush wildlife before making a lower -repass for a neater finish.
And before you mow, wildlife will thrive from the benefits of your mini meadows such as all of the nectar, pollen, shelter and structure wildflowers provides!
Grass pollen can definitely be a cause of hay fever but longer grass in May is unlikely to be a big driver of high pollen counts in your area.
We know how hard hay fever can be – and all allergies must be taken very seriously. We would not advocate any garden maintenance regime that negatively impacts on residents’ health.
The occurrence of ticks in gardens is increasing, so you should wear long trousers and examine yourself carefully for ticks whenever you’ve been in long grass or other long vegetation.
Ticks are very small insects that spread a serious bacterial infection called Lyme disease. The ticks live on mammals such as hedgehogs, badgers and foxes and then drop off into long grass and vegetation, where we can pick them up and become infected. If you are bitten by a tick look out for flu-like symptoms such as feeling hot and shivery, headaches, aching muscles or feeling sick, and a circular red rash around the tick bite.
In areas where ticks are prevalent, consider maintaining a shorter grass lawn mown once every four weeks. For more information see www.nhs.uk/conditions/lyme-disease and www.lymediseaseaction.org.uk
