What do you think of when you hear the word ‘weed’? Join us as we uncover the myths #and delve into what it really means.
It’s a word we’re all familiar with, and one we hear often, especially during our annual No Mow Movement – ‘What about the weeds’?
The Cambridge Dictionary defines a weed as, ‘any wild plant that grows in an unwanted place’.
If you were asked to picture a weed, perhaps some people would think of a Dandelion pushing up through the pavement, or a lone Forget-me-not lurking in your lawn. Many people think of specific plants as ‘weeds’, but that’s not true.
So, join us as we weed out the myths of the word ‘weeds’.
Here’s the thing – the actual definition of a weed is simply, “a wild plant growing where it is not wanted, especially among crops or garden plants.”
Just a plant, in a place we didn’t choose.
Technically speaking, any plant can be a weed. Even our most treasured native wildflowers such as orchids, simply for existing in a spot we decided they shouldn’t.
So, what makes people think of a Dandelion as a weed but an orchid as a prized plant? It’s simply perception and context.
The word ‘weed’ has been part of the English language since at least the 9th century.
It’s believed to have come from the Old English word ‘weod’, which simply means a plant – including herbs or even trees.
Over time however it took on more of a negative tone, especially as agriculture became more dominant and plants that competed with crops then took on the name.
By the 19th and 20th centuries, with the rise of industrial farming and garden landscaping, ‘weeds’ became enemies. Something to spray, pull, or pave over.
But in nature there are no weeds. Just plants doing what they’ve always done – growing, spreading, surviving.
Non-Native Invasive Species aren’t weeds by definition, but they certainly can cause problems.
Non-native plants are simply plants that have been introduced to the UK, that naturally grow in other parts of the world.
Not all non-native plants become problems – many of them integrate into our habitats without causing damage (these are called ‘naturalised’ species). However, some thrive in our habitats, so much so that they out compete our native plants, these are known as Invasive Non-Native Species (INNS). These include common garden centre finds such as Rhododendron.
One in five species of UK vascular plants are at risk of extinction. The second biggest threat to biodiversity is Invasive Non-Native Plants, so they must be taken seriously.
Read our blog here to find out more.
While the majority of plants have value to wildlife, some can cause problems, mainly to other plants around them.
Think of a thicket of nettles for instance, there’s not much biodiversity in the swathe as it has a tendency to takeover. While large amounts of such plants can cause problems, small amounts are That said, it’s important to remember the benefit that plants, including nettles bring to our other wildlife. Nettles can be a great addition to your green space and support more than 40 different insects and butterflies!
So, while problem plants aren’t necessarily ‘weeds’ we recognise that some plants could benefit from some careful control. Read our blog here, to find out how to manage problem plants such as Thistle and Common Ragwort.
We ran a survey recently and found that 56% of people think of Dandelions as a weed. That’s not a huge surprise – Dandelions have had a bit of a PR problem. But the truth is, they’re not ‘weeds’ but wildflowers. And quite useful ones, at that! In fact they were once revered as a cure all medicinal herb and even appear in ancient Greek mythology.
Watch our video below to find out why we should rekindle our love of the humble Dandelion.
Dandelions are amazing! Did you know that Dandelions support more than 50 species of insects? Or that Dandelions have been used in medicine for centuries?
The good news? More than 90% of 19-24 year olds in our survey said they see dandelions and daisies as wildflowers, not weeds. This gives hope for the future of our native wild plants.
Perhaps in the future we will all see ‘weeds’ differently – as part of a bigger picture. ‘Weeds’ are our native plants and part of the planet long before we were. They make up important habitats, improve biodiversity, provide food and even medicine, they even capture carbon!
Let’s change our perspectives to see ‘weeds’ for what they really are, wildflowers that are symbols of resilience, beauty and wildness.
Our meadows have been part of our natural heritage for centuries and cared for by people for generations – but they are now more at risk than ever before.
Did you know that the rainforest can glow in the dark? Or that it’s home to plants which were on the Earth before the dinosaurs?
What do you think of when you hear the word 'weed'? Join us as we uncover the myths #and delve into what it really means.

Congratulations – we’ve reached the end of No Mow May! On behalf of your wildflowers and pollinators, thank you for breaking with convention and for re-imagining your lawns and your local green spaces.
But the buzz doesn’t have to stop there…why not leave a space in your garden for nature to continue to bloom this June? From different grass lengths, how to look out for wildlife and how to mow (if you want to) – follow our expert advice to continue your No Mow Movement.
By not mowing in May you have taken the first step in the No Mow Movement, boosted the wildflowers and thrown a much-needed lifeline to your pollinators. Hopefully you can already see the difference you’ve made and are pleased with the results (we know we are!).
Now the growth season moves into June, things don’t have to get messy or overgrown and you can still maintain a space for your local wildlife. If you’re wondering what to do or concerned about your mower not being able to cope – we have some ideas about how you can build on your success while keeping things under control! But importantly, your lawn or open space is your canvas and you hold the paintbrush.
You now have an opportunity to design your wildflower landscape. Grassland wildlife comes in different flavours and you could incorporate these different elements into your plan.
You might need to keep your paths and recreation areas mown short but perhaps you could frame these functional areas with a flowering lawn mown once every 4 to 8 weeks. This allows common, low-growing wild flowers to regrow and reflower throughout the summer while you maintain a shorter, neater height. Picture a carpet of red and white clovers, golden trefoils, puddles of blue selfheal and the white froth of yarrow. You will find that even in the fiercest droughts, the wildflowers will stay green and keep flowering while grasses fall dormant and turn brown.
If you are feeling bolder you might want to trial leaving some of your open space unmown for longer. By mowing only twice a year outside of April to July you could try to recreate the effect of a traditional hay meadow. This allows taller growing flowers such as red campions, purple knapweeds and mauve scabious to grace your space with a more dynamic swirl of colours animated by a summer breeze. You can picture this flavour of grassland as a perennial, herbaceous border you never need to weed feed or water. It holds more value for wildlife because when left undisturbed for longer, wildflowers and grasses can support the lifecycles of those invertebrates that depend upon them.
The more adventurous among you may want to take it to the next stage around the boundary of your plot. Grassland left unmown won’t support so many wildflowers but will provide vital sanctuary for wildlife during hot summers and cold winters. Tussocks of grass and tall herbs will develop, and this structure is a great way to provide another niche for wildlife that complements the more flower-rich areas. Such sanctuary strips need only be a few feet wide at the base of your hedgerow and they only require a minimum of management when you snip out woody saplings or the bramble gets too much. You will be providing vital protection for toads and voles while seedheads will act as natural bird feeders for visiting finches.
Leaving borders to grow supports a wealth of wildflower and wildlife
By the end of No Mow May, your garden lawn may also look like this!
Creating a patchwork of lawn lengths in your garden can support a range of wildflowers
Some of the tools Mark uses in June to manage his lawn
If your grassy growth has gotten away from you, don’t panic. Not all mowers can cope with tall vegetation but most can if you mow in two 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.
This will prevent the build-up of cuttings which can stifle the regrowth of wildflowers. With no cuttings to rot back down into the soil, it will also help to reduce the fertility of the soil. More fertility gives the advantage to your grass over your flowers. This produces a lush green lawn but it will be much less colourful and much less valuable for wildlife.
If collecting up or raking off your cuttings seems like more work, remember that you are actually saving effort by managing some zones less frequently. This means that you don’t have to mow everywhere all at once every time. In fact, by removing the cuttings each time you cut, fertility will reduce each year meaning that regrowth will be less and less each year. That means you won’t need to cut so often in the future so you can save yourself the effort, reduce your carbon footprint and enjoy the wildlife! Wilder lawns also capture and lock away more carbon in the soil, so you will be doing your bit for the climate too.
You can use cuttings to mulch your vegetable beds to suppress weeds, retain soil moisture and add fertility where you want it. Composting is also a great way to recycle your cuttings with other organics into soil you can use next season.
Some wildlife may have taken refuge in your liberated lawn. Here are some quick tips for keeping wildlife safe while you mow:
It’s not too late to join Plantlife’s No Mow May. It’s is one of the easiest ways to connect with wildlife and the perfect way to start supporting nature in your garden (in May and beyond!).
Join to help us understand how much space is being left for nature and for free goodies and tips.
Ultimately, it’s your lawn and your choice – to manage as you wish. You can rekindle wildflowers from those that are already present and the seeds that have remained naturally dormant in the soil. You might also consider introducing some native perennial wildflower seed or native perennial wildflower plants this autumn. We will have more advice on this later in the year.
However you choose to enjoy your new wildlife area, we wish you every success. Now that you have added a little more colour to the world, we hope you are rewarded with the fizz of grasshoppers, the delight of birdsong and a space that dances with butterflies and buzzes with pollinators.
We would love to see how your No Mow Movement is going – whether that’s pictures of your garden, the flowers blooming or the wildlife that comes to visit. Share your pictures, videos and stories by tagging us on Instagram, Facebook, X (formerly Twitter) and Bluesky.

The changes to insects, wildflowers and people have been ‘mind-blowing’ since the National Museum of Scotland started taking part in the No Mow Movement.
We asked Entomology Curator Ashleigh Whiffin how it’s made a positive impact to insect biodiversity and how it’s helping her work as an entomologist.
Watch our full video below.
I have always been a big supporter of No Mow May and the No Mow Movement because I think it’s an incredible campaign for raising awareness of wildflowers and this is vital if we’re going to improve the available habitat for insects.
There had been an interest among staff in participating in the No Mow Movement, but really what spurred it on was the lockdown periods. During this time the contractors didn’t come in to mow the grass and displayed a little version of what could be.
Initially, we just wanted to see what was here naturally. The site had been manicured for many years, so the grass was incredibly short and flowers were not given the opportunity to bloom.
When we first left the site to grow in lockdown, we started to see wonderful flowers like Oxeye Daisy and Cuckooflower – things I know insects love.
Native wildflowers are most important to insects because these are the species that they have evolved alongside and they provide them with the exact food sources they need.
We have also done a little bit of enhancement and added Primroses and Cowslips to the grassland to provide an early supply of nectar and pollen for some of our spring pollinators. And then we’ve also added Yellow Rattle, which has probably had the biggest impact. The Yellow Rattle has spread throughout the 4 years that we’ve been doing this project, and it’s really made quite a difference.
I think my favourite flower is possibly the Common Knapweed because I love its bright pop of colour and seeing a bee really stuck face-first deep into the flower is really satisfying.
One of my favourite things about us participating in the No Mow Movement has been the insects that we’re recording, including things that were not here before.
Everything from butterflies to moths to beetles and bees – and one of the biggest noticeable differences is the number of butterflies in recent years.
We’ve recorded 16 species of butterflies on our site during this period. They’re not all breeding here but that number is almost half of the butterflies recorded in Scotland, so that’s pretty good going! And because we’ve allowed our areas to grow, we found that we have a wonderful population now of Small Skipper butterflies.
The adult butterflies really need the floral resources to get the pollen and nectar. But their offspring need some breeding habitat, so the diversity of grasses we have are really important.
I’ve loved being able to work with my colleagues out on the grounds and interact in different ways than we usually would. It definitely has the mental health benefits to many of the staff and volunteers.
Also, the sounds of nature. Sitting near the meadow on your lunch break and hearing the grasshoppers and seeing the butterflies dance along the meadow – it’s a really nice experience.
There’s also a feeling of satisfaction, knowing that we’ve made these changes and they’ve been really positive.
The management plan that we developed has totally rewritten what was happening here before and we have transformed the site during the course of the last 4 years.
Instead of the grass being cut every 2 weeks, we have just particular areas of the grass that are cut. Most of the grassland is left and we just have edges of the green spaces, the perimeter of the site and then designated pathways cut during the growing season. We also leave areas long all winter to create habitat for wildlife.
It’s been a delicate balance of trying to make sure that we’re enhancing the biodiversity but not disrupting any access.
The National Museum’s collection centre is in the north of Edinburgh in an urban area. Our site is pretty unassuming – it’s an urban plot that is a series of buildings with green spaces laced between them.
But we have become a little bit of a green haven for the local wildlife.
As an institution, the No Mow Movement really nicely aligns with our aims as we research biodiversity, particularly Scottish insects, which is one of my focuses.
And of course, we’re very concerned about the environmental and biodiversity crisis right now. So doing something more with our own green space that we have was a natural way forward. I really hope that what we’ve done on our site can show other organisations what’s possible.
If I had to list everything that we found, we would be here for a very, very long time. We’ve got countless moths, butterflies, bees and bugs including:
With insects being more plentiful, that’s also been great for the birdlife and we’ve had Blue Tits and Great Tits nesting on site and foraging, collecting caterpillars for their young.
We’ve also had a number of mammals, some of which can’t be recorded in the day. So, by setting up camera traps, we’ve been able to see some of the nocturnal wildlife, predominantly that’s our foxes.
The biodiversity loss that we’re facing and biodiversity declines that we’re seeing are a very real and quite scary issue.
Now more than ever, it’s so important that we use any little scrap of space that we can to make things a little bit wilder and support our biodiversity.
By participating in the No Mow Movement it’s given us this whole opportunity to look at the insect life and our biodiversity right on our doorstep at the Collections Centre in a totally different way.
It’s clear that by giving power to the flowers and encouraging those native grasses can have a huge impact on our insect biodiversity.
Plantlife's Road Verges Advisor Mark Schofield reveals how to keep your thriving No Mow May flowering lawn blossoming into June.
The National Museum of Scotland has transformed its collections centre into a haven for insects and local wildlife by taking part in the No Mow Movement. Learn how.
It’s not just our wonderful wildflowers which benefit from not mowing our lawns this May – our pollinators, birds and wildlife flourish when we manage our lawns for nature!
Pollinators and other wildlife bring our gardens to life with buzzing and fluttering along our lawns, borders and hedges.
From bees to butterflies, and beetles to hoverflies, the wildflowers keep them thriving in our neighbourhoods. Here are just a handful of the species which you can spot in your garden this May and beyond.
And if you haven’t already, why not join the No Mow Movement and help pollinators from home.
Read our blog on creating a pollinator friendly garden here, for our top tips on their favourite flowers!
The dappled pattern of the Speckled Wood is a sign that summer is on its way. With up to two generations of this sun-seeking butterfly being produced in a year, it’s crucial that its caterpillar food plants, long grasses such as False Brome Brachypodium sylvaticum, Cock’s-foot Dactylis glomerata and Yorkshire-fog Holcus lanatus are available. This is why leaving patches of long grass year around in your garden is so important!
Living up to its name, this bumblebee can be seen across the UK in spring with its vividly red tail. Bumblebees like this one rely on a plentiful supply of our wonderfully wild plants such as Red Clover Trifolium pratense and Dandelions Taraxacum officinale to supply them with nectar and pollen. These are food sources for the bees and their larvae – next year’s buzzing bumblebees!
The life cycle of this bright and boldly patterned moth (pictured in the heading) relies entirely on one of our sunniest wildflowers – the yellow Common Ragwort Senecio jacobaea. Its tiger-striped caterpillars munch on this unpalatable plant before pupating underground over winter, ready to emerge as moths and put on another dazzling show next year.
This deliciously named hoverfly is one of our easiest flies to spot, identified by its black and orange bands and mesmerising levitating flight. Despite being disguised as a wasp, this friendly pollinator relies solely on nectar from flat flower heads such as Common Ragwort Senecio jacobaea and Cow Parsley Anthriscus sylvestris.
Commonly known as the May Bug, these chunky red/orange beetles only live for 5-6 weeks. Despite their short lives above ground, females rely on grassy areas such as lawns to lay their eggs, where the larvae develop hidden deep underground for up to 5 years. Look out for them on warm evenings, perhaps bumping into your lit window!
By letting us know if you or your community space is taking part, you’ll be added to our map showcasing the collective power that this campaign has.Now sit back and watch the wildflowers grow…
We can’t wait to see your blooming wonderful communities this No Mow May!
It’s estimated that there are 23 million gardens in the UK – that’s a lot of land with which we can be gardening for wildlife!
Bees, birds and butterflies are not only beautiful in their own right, but are useful for the gardener, from pest control to pollination. Bees help pollinate flowers and food. Frogs eat slugs. Birds and ladybirds help keep aphids at bay.
If you want to create a home for wildlife in your garden, here’s a couple of nature-friendly gardening jobs to inspire you. If you create the right space, nature will come.
Wild plants are great for wildlife. This is because our native plants and animals have been around longer than species that have been introduced to this country. They’ve evolved together and are more likely to support and sustain each other.
Not got a lawn? Small bushes and trees, and many wildflower plants can be grown in pots!
Simply leaving patches of lawn to grow longer will allow flowers to bloom for bees and butterflies and provide shelter for small mammals such as wood mice, voles and shrews.
Be part of Plantlife’s No Mow May movement and leave the lawn mower in the shed this summer – if you want to take it a step further, we recommend leaving some areas for much longer between mows. Different lengths of grass left in your garden for the whole year will welcome and provide a home for much more wildlife. Shorter grass welcomes clovers and daisies, and grass that has been left to grow all year is a paradise for butterflies and other wildlife.
One of the best ways to bring wildlife into the garden is to build a pond. It doesn’t have to be big – a container such as a washing bowl or old sink will do. But it needs to have at least one sloping side or ramp so that creatures can easily get in and out.
Put your pond somewhere partially sunny and wait for it to fill with rainwater for best results. Bring it to life with native plant species such as Marsh Marigold Caltha palustris, Water Avens Geum rivale and Bogbean Menyanthes trifoliata.
In summer and during heat waves this water source will be a vital lifeline for thirsty birds, as well as a space for flies such as dragonflies and hoverflies to reproduce.
Leave the untidy corners and wild areas – it might be tempting to start tidying up the garden before the growing season starts, but these areas of leaf litter, twigs and longer grass along fences or hedges are perfect spots for insects, reptiles and amphibians to have been sheltering over winter. If you start to tidy it up too early you could be disturbing a slumbering creature that isn’t ready to spring into action until the weather starts warming up.
This also goes for the remnants of last years plants in your borders or pots. Sometimes these dead stems and leaves are perfect for insects to hide in whilst it’s cold and damp. Therefore leave these up all winter if you can and only ‘tidy’ up when the spring days are warm enough.
Maybe this will be your first year doing No Mow May, in which case you might want to spend a bit of time planning where you want to leave long all summer long, where you maybe want to mow monthly and where you want to have short or paths for walking around. You could draw up some designs even for creating wild and wonderful shapes. Or you could simply devote your entire lawn or green space to the way of the meadow!
Plantlife’s No Mow May is here – let’s give power to the flowers!
It’s is one of the easiest ways to connect with wildlife and the perfect way to start supporting nature in your garden (in May and beyond!).
A rainbow of wildflowers in your lawn doesn’t just bring garden owners joy, but it is also the sign of a healthy and thriving garden.
Learn how to increase the number of wildflowers appearing in your lawn this year with our expert guidance.
Different flowers provide different resources for different wildlife species. Clover on a short flowering lawn provides a lifeline for bumblebees, long grasses provide an essential resource for butterflies and moths such as the Small Skipper, and Goldfinches are attracted to Knapweed when it sets seed.
But how do you increase the diversity of plants in your garden? Here are some tips from Plantlife’s wildflower experts to help you create a blooming bonanza!
They are some of the first lawn flowers to appear each year and provide much needed food to early bees and other pollinators when there is little else out in flower. Sparrows also enjoy feasting on their seeds as a tasty snack.
It’s not just trees that capture and store carbon, our meadows and grasslands play an important role too.
If you’re taking part in No Mow May this year, then your garden will be well on its way to becoming a beautiful, biodiverse haven for nature. But there is a bonus to helping the wildflowers grow – as you allow lawn to become meadow, your garden becomes your very own carbon store, helping to reduce your carbon footprint.
When carbon sequestration is mentioned, most minds turn to trees. As a society we are more aware than ever before of the role of woodlands in combatting climate change and creating a space for nature. Much less discussed is the remarkable and equally vital role our grasslands and meadows can play in increasing biodiversity and capturing and storing carbon from the atmosphere.
When we create healthy grasslands and meadows by mowing or grazing livestock, we are simply replicating the activity of the herds of large wild herbivores that once moved across our hills and valleys. These habitats – if the grazing is gentle, infrequent and low intensity – recreate prehistoric landscapes and provide a home for our wild plants, insects, birds and fungi. Natural and semi-natural grasslands (meaning those that are farmed but in a traditional, less intensive manner) improve the quality of our water, prevent flooding and help increase the resilience of farming to summer droughts.
This grassland – and the healthy soil beneath it – also has an incredible and little-known potential to lock away atmospheric carbon. Soil carbon is a particularly valuable store; it is far more stable and long lasting than the carbon in trees, which is vulnerable to forest fires, pests and disease.
As plants live and grow, carbon from the atmosphere is drawn down into the plants’ roots, where the myriad creatures in the soil make use of it, locking it away beneath the ground. As the diversity of plants on the surface increases, so does the diversity of microorganisms, fungi and invertebrates beneath it. The more diverse the soil life, the richer the entire ecosystem – and the more carbon the soil can store.
The almost mystical role of mycorrhizal fungi is now well known. They connect roots to the nutrients in the soil, trading sugars that plants and trees create from sunlight with locked away minerals the fungi extract from the soil. We now know that plants and trees can communicate through these fungal networks, alerting them to pests and diseases and passing nutrients to others in need.
Mycorrhizal fungi have another important role – they are critical in the ability of plants to transfer carbon to the soil. In areas of farmland, meadow and garden where the soil is ploughed, fertilised or dominated by a small number of grass species, these mycorrhizal networks are much less effective – with fewer species and a lower carbon storage potential. When we look after our farmland and gardens with care, mowing and grazing infrequently and gently, avoiding ploughing and pesticides, we nurture our mycorrhizal fungi, helping the soil to become a more potent carbon store.
By taking part in No Mow May, you will not only begin to create a home for wildflowers and insects, you will also create healthier soils that nourish your garden plants – and reduce your carbon footprint in the process.
England alone has around 640,000 hectares of private garden. If just a quarter of this area was transformed into wildflower rich meadow – by mowing just once or twice a year and collecting the cuttings – then these garden soils could potentially capture and store an additional amount of carbon equivalent to more than 3 million average cars’ annual emissions within a spade’s depth, and well over 10 million cars in soils as deep as one meter*.
Lawns and gardens are of course just one part of the puzzle – the UK’s farmed grassland landscape offers tremendous potential for us to sequester carbon, while also protecting agriculture and biodiversity.
Farmers and landowners have a fundamental role to play – combining food production with sustainable grasslands that lock away carbon in healthy, ecologically rich soils. Some 40% of the UK’s land area is grassland – but much of this is intensively farmed, limiting its potential for carbon storage.
Globally, studies have suggested that 2.3-7.3 billion tons of CO2 equivalents per year could be sequestered through grassland diversity restoration. Carbon sequestration doesn’t just mean more trees. Healthy grassland, with the more sensitive grazing and less intensive farming that nourishes it, also keeps carbon out of the atmosphere.
No matter how large or small our garden, we all have a role to play, and we can all make a difference. It’s easy to get started – just put your lawnmower away this May!
It’s not just wildflowers which benefit from not mowing our lawns this May. Pollinators and other wildlife bring our gardens to life!
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.
Why not check out our No Mow Movement Calendar for top lawn tips throughout the year.
The No Mow Movement Calendar
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 2 to 3 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:
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.
Read our Increase the Number of Wildflowers in your Lawn blog here to find out more.
Increase the Number of Wildflowers in Your Lawn – Plantlife
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
The sun is shining, the days are longer and our green fingers are ready to get stuck back in to some spring gardening.
Our gardens have the ability to become havens for nature. Increasing biodiversity, encouraging native wildflowers, letting our lawns grow wild and even planting mini meadows are all excellent ways to have a more nature-friendly garden.
As we enter spring, our minds are definitely turning to the jobs we can get stuck into in the garden, to get ready for a blooming good season.
Our Specialist Botanical Advisor Sarah Shuttleworth is on hand with expert advice for jobs you can do now.
Mow – sounds counter intuitive but actually if you can get the mower going over your lawn or No Mow May areas a couple of times before April/end of March then you will give the other species hiding amongst the grass more of a chance. This is particularly important if you have sown Yellow Rattle seed, although once you start finding the Yellow Rattle seedlings appear and are tall enough to be affected by a mow, then that’s the time to leave the mowing to allow them to grow.
No this doesn’t have anything to do with roofs. Sometimes our lawns and other grasslands can get a bit clogged up with dead plant material (known as thatch), like dead grass or old cuttings that didn’t all get picked up by the mower.
This thatch can reduce light levels to seeds waiting to germinate or other plants wanting to get growing in the spring, plus it can add nutrients to the soil, which might sound great, but not for native wildflowers trying to compete with the vigorous grasses.
Therefore during February and again next winter from autumn (although check for grassland fungi first, you don’t want to disturb them if you are lucky enough to have them in your green space) you want to rake out the thatch.
If you don’t have a lawn, what about creating some meadow planters? Tubs, pots or deep trays could be sown in April with a meadow mix. This will ideally be one that is a mix of grasses and wildflower seeds, which will avoid gaps for weeds to arrive.
Remember our native meadows are mostly full of native perennial species (plants that live more than one year) rather than Cornflowers, Poppies and similar, which are annual species associated with disturbed soil like that of farmed fields.

Often gardening tips to get your garden ready for spring, include prepping your lawn. The main focus of this is usually to feed your lawn, but this will only promote the vigorous grasses to out compete everything else, leaving the tiny speedwells, mouse-ears, and medicks getting crowded out!
Hopefully our top tips have given you some inspiration to get out and enjoy the spring sunshine while sprucing up your lawn or garden.

Known as nature’s meadow maker, Yellow Rattle, is the single most important plant you need when creating a wildflower meadow.
Here’s everything you need to know.
Yellow rattle, commonly known as the meadow maker, is one of the most important plants you need for a meadow. Without it, vigorous grasses can grow unchecked and smother flowers you want to encourage.
As Yellow Rattle Rhinanthus minor grows in a meadow the grass will become thinner, making room for plants like Oxeye Daisy, Knapweeds and Vetches to appear. And if you’re lucky, maybe even an orchid will pop up.
Then large bees, especially bumblebees, move in and pollinate the flowers of yellow rattle and it’s large seed pods dry and ripen. This leaves the seeds rattling around inside. Farmers used to use the sound of the rattling seeds as their cue to cut the hay – hence the name.
Yellow Rattle is a very useful starting plant when making a wildflower meadow, but it can be a little tricky to establish. Here are some top tips to get you started:
If you have very fertile soil, it might be trickier to grow Yellow Rattle. Poor and infertile soils are best and following the steps above will help reduce the fertility of your soil over time.
Your go-to guide for transforming places into flower-rich meadows.
Late summer (August-September) is the best time to sow Yellow Rattle. It will not grow successfully if sown in the spring. The seeds can be sown no later than November because they need about 4 months below 5C to germinate in the spring.
Yellow Rattle is easy to collect by hand. Simply hold a paper bag under the ripe seed pod and shake it gently with your fingers. Collecting larger quantities can easily be done using a vacuum or leaf blower.

There are a number of reasons why Yellow Rattle may disappear from a meadow, including:
For meadows, we recommend 0.5-2.5kg per hectare/10-20g per m2 if you are collecting your own seed.
There are several possible reasons:
Managing or making meadows, whether in a lawn or larger site, can sometimes lead to prickly problem plants like docks or nettles. Follow our expert advice for managing problem plants.
