The No Mow May campaign started, primarily because of the significant loss of species-rich grassland across the UK in the last century. With more than 23 million gardens in the UK, we saw an opportunity. If lawns and green spaces could be left to grow they could recreate pockets of mini meadows.

We’ve seen wildlife thriving in No Mow areas – from bees feeding on pollen, amphibians sheltering in the longer grass, mammals thriving in the new habitat and stunning wildflowers being allowed to bloom freely.

Also, it’s super easy to take part – sign up, stop mowing, sit back and let it grow!

How No Mow May Can Help Tackle Climate Change

Juv. Grasshopper on a yellow Rough Hawkbit - smaller

Did you know a No Mow patch where the wildflowers and grasses have been allowed to grow in May and beyond can help combat climate change? Not to mention, these spaces can provide vital refuge for wildlife during our changing climate.

By mowing less, the number of grass and wildflower species gradually increase over time. This creates a more varied soil structure and more biomass in and above the soil. This helps to lock away more carbon than a plain grass lawn, that might only have a few species in total.

Many studies have also shown that an increase in plant diversity may greatly increase the amount of carbon that can be stored and the rate at which this happens. [1]

In fact, species-rich grasslands are very important carbon sinks. It’s not just peat bogs and woodlands that need protection for their role in tackling climate change.

How to Cut Carbon Footprint and Save Money on Energy Bills with No Mow May

It’s also important to remember that by simply mowing yes, you are also helping to do your bit for the environment. Now that you’re caring for your garden with nature in mind, you might only need to mow paths or play areas on a regular basis – rather than your whole garden.

This also saves time, so you can sit and admire the gently swaying grass and hear the hum of busy insects instead!

At the end of the summer, you can continue to mow your lawn as normal. However, you might find that the grass grows less vigorously year on year, requiring less time mowing in the long run too.

How No Mow May Cools Cities

Leaving longer grass in your garden or green space can also help to cool larger urban areas. Grassy areas left to grow are crucial in an urban environment – not only for our wellbeing, but also for regulating local environmental temperatures.

Urban green spaces can help to cool cities and are also able to influence the surrounding area. This phenomenon is called the urban green space cooling effect [2]

If grasslands within green spaces (lawns, parks, playing fields etc) can also be managed to have more vegetation and a mix of grass lengths, these benefits can be increased.

A study in 2021 showed that increasing plant structural complexity and/or diversity (meadow areas, hedges etc) increases heat mitigation and habitat for invertebrate biodiversity compared with regularly mown lawns management. [3]

Helping Climate Change From Your Doorstep

So, whilst you sit and relax amid your No Mow area, take a moment to think about the increased resilience your lawn now has when faced with our increasingly dry and hot summers.

The summer of 2025 was extremely hot and dry for most parts of the UK, particularly the east of England. Many lawns turned yellow-brown early in the season and were slow to recover.

However, anyone doing No Mow May into June and July would have found their grass was much healthier and still green at the base. These areas were noticeably cooler too, providing much needed shelter from the sun for many creatures, pets and humans alike!

To help tackle climate change from your garden or green space, pledge to take part in the No Mow Movement.

Top 5 Butterflies to Spot in May

We’re not the only ones who love all the benefits of No Mow May!

Here, the Butterfly Conservation joins us to give their top 5 species to look out for in your No Mow Movement area.

May has arrived and with it, sunshine, blooms and busy butterflies looking to complete their lifecycles. 

Butterfly Conservation research showthat allowing patches of grass to grow long can boost butterfly numbers by up to 93%, so taking part in No Mow May, as well as things like planting sources of nectar and avoiding pesticides, can all help create a welcoming space for butterflies to thrive.  

But which butterflies might you spot in your garden and local green spaces this month? 

Photograph shows a beautiful Speckled Wood butterfly with it's wings open, perched on a yellow flower. The butterfly has brown wings with light yellow patches on them.

1. Speckled Wood 

This beautifully patterned brown and cream butterfly flies from April to October and likes to bask in sunny spots. 

It’s a fan of gardens and, if you’ve got a long lawn, you might also spot its vivid green caterpillars, which like to munch on grass.  

Photograph shows a close up of an Orange Tip butterfly on a Forget-me-not. The butterfly has it's wings open towards the camera. They are a creamy colour with orange tips.

2. Orange-tip 

The Orange-tip only flies for a short time between April and June, so May is an ideal time to get out and spot one. Look out for a flash of orange on the tip of the wings of the males (lending it its name) or a black tip for the females.

Orange-tips also have a beautiful speckled green pattern on their underwings which help to tell them apart from other white butterflies which fly at this time of year. 

Photograph shows a Red Admiral Butterfly landing on wildflowers in a longer lawn,

3. Red Admiral 

The Red Admiral is a familiar garden favourite that can be seen in almost any month of the year – even December! 

It has striking, orange-red wings and a powerful flight which make it hard to miss but sometimes difficult to get a proper look at. 

Photograph shows a close up of a butterfly with outstretched wings on a Cuckooflower.

4. Peacock 

One of the UK’s most distinctive butterflies, the Peacock has bright and colourful wings with bold ‘eye-spots’ on them which it uses to ward off predators. 

However, despite its showy upperwings, with its wings closed, it looks like a dead leaf – you’ll have to keep a careful eye out to spot it. 

Holly Blue The Holly Blue is a small, powdery blue butterfly with a delicate flight. In May, you might spot it flying high around bushes and trees, particularly Holly bushes, which it lays its eggs on in spring.

5. Holly Blue

Yellow Rattle: The Meadow Maker

Yellow Rattle, is the single most important plant you need when creating a wildflower meadow. Here’s everything you need to know.

1. Start a Community Meadow

Creating a meadow is a really simple way to bring the local community together, whilst doing something positive for nature. So, what are community meadows? They are areas, predominantly of grassland, that are owned and managed by the community, such as parks, road verges, school grounds, village greens, church land or fields.

You don’t need to be an expert to start one – we’ve shared our tips for how to begin, what to plant, how to manage your green space year-round and how to engage the community.

Take a look at out guide

2. Talk to Your Neighbours

You may not have your own lawn or green space, but your neighbour or community might! If the 23 million garden owners of the UK joined forces for nature, it could transform the fortunes for our wild plants and the much-loved wildlife that depend on them.

Why not share our No Mow May resources with your neighbours and community? We’ve got posters, signs, pictures and social media cards which are a fantastic conversation starter – it could even be the start of a No Mow May street! 

3. Get Schools and Educational Hubs Involved


As well as a place to grow our curiosity, our educational spaces can be home to playing fields, verges and gardens which are ready to burst with life each spring. If your school isn’t taking part already, consider having a chat with staff to see if a space can be left for nature this year. As well as being a bonus for wildlife, why not use this as a fun learning opportunity to discover how many species you can spot? 

4. Chat to your Local Councillor

Whether it’s parish, town or district council, reaching out to your local decision makers to promote wildlife-friendly management can make a big difference. Local support can really help to bring about change, whether that’s through a volunteer group or social media page. Check out our Good Meadows Guide for some convincing talking points or the Flowers on Roadside Verges Facebook group for some inspiration.

Our councils manage some of our most widely-used green spaces, no matter where you live. Ask your local councillor about your councils plans to provide a home for wildflowers and wildlife in May and beyond, and share their good work on social media. 

5. Create a Mini Meadow in a Pot

If you have outdoor space but no lawn, don’t write off No Mow May just yet! Encourage wildlife to your garden with a pot or window box – what happens if you leave one with bare soil, perhaps local wild plants seed will find their way in. There are also native seed mixes you can sprinkle into pots which pollinators like bees and butterflies will go wild for! 

 

6. Connect with Places of Worship  


Often the cornerstone of our communities, our places of worship can be a sanctuary for people and wildlife alike. See if your local church, mosque or other place of worship has a green space they can pledge for nature this No Mow May. Churchyards for example, are often excellent places for wildflower and wildlife that enjoy the undisturbed grasslands.

Join us for a deep dive into your spring lawn and learn everything you need to know about how to prep for the best No Mo May!

Dandelions and daisies on a Wiltshire lawn

Plantlife’s No Mow May gears up in spring, and every year it’s gaining more and more momentum – but if you’ve never taken part before, where do you start?

The journey is all up to you and it can be as simple or as green-fingered as you like.

So if you’re looking for some ideas to get you started, here’s some of our top tips to get you on your No Mow way.

Get Ahead with Everything You Need to Know About No Mow May

Starting a new journey with your precious garden can be daunting, and we know that many people have lots of questions – from what happens when you stop mowing, to which flowers might pop-up.

So to help kick-start your journey, we’ve put together a handy guide with everything you need to know about the No Mow Movement – it’s the perfect place to get started.

The important thing is not to be intimidated and to give it a go – every wild patch can add up to huge gains for nature. And the 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.

What Should You Do to Your Lawn in April to Prepare for No Mow May?

It’s completely up to you how you prepare – you could just get to the first of the month and pack the mower away.

But there are a couple of things you could try to give your lawn the best chance of beautiful biodiversity:

  • Firstly, don’t feed your lawn – it will only promote the vigorous grasses to outcompete everything else.
  • Sow your springtime seeds! Some native wildflower seeds you’ll want to sow in the autumn, such as Yellow Rattle – but others can be sown in April.
  • Try sowing a mini meadow in a planter and see what comes up.
  • And pledge to take part and get a FREE No Mow May guide!

What Should You do to Your Lawn in May?

That’s up to you – but we’d recommend pledging for No Mow May, flicking through your FREE guide (complete with wildflower ID), grabbing a cup of tea and basking in nature!

When May starts, the easy bit begins: sign up, stop mowing, sit back and let it grow.

May is a great month to get started, because that’s when most of our wonderful wild plants are getting going for the season. Giving them time to grow 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 springboard for managing your lawn for nature year-round. If you can make a start in May, that’s brilliant.

But really, this is part of a much bigger movement of caring for your garden to help nature. The goal is to mow less for longer, and to manage our lawns like mini hay meadows.

Do I Need to Sign Up to Take Part in No Mow May?

By pledging to take part in the No Mow Movement, you’re joining a community of people all caring for their gardens and greenspaces with nature in mind. And the more grassy spaces helping wildlife, the better.

It’s very easy and takes just 2 minutes to pledge and get your FREE No Mow May guide.

Please pledge today (you can join at any time from March to June) and help us see how many people are helping nature by letting it grow.

How to get the Best Results from No Mow May?

You can just stop mowing and see what comes up – in fact, the plants growing in your garden can even give you a bit of a history lesson on what your garden might have been in a former life.

But if you want to give biodiversity a bit of a boost, there’s a simple trick – variety!

If you keep 2 to 3 different grass lengths throughout the summer, it can help maximise flower variety as well as the nectar they produce for our precious pollinators:

  • Long and lush: If you can leave some areas unmown all year, you might encourage some of those taller wildflowers like Oxeye Daisy and Field Scabious to bloom. You could create longer patches in lawn corners or along boundaries. These tall grassy areas can also provide food, shelter, and nesting spots for wildlife like hedgehogs and toads.
  • Mid-length ‘meadows’: For mid-length areas you need to mow just 2–3 times a year. Leave it to grow between April or May and August to encourage taller summer flowers like Meadow Cranesbill, Musk Mallow, and Knapweed. Then mow as normal outside of these months.
  • Short and sweet: Mow the rest of your lawn once a month to a height of 1–2 inches. This allows low-growing plants like daisies and Bird’s-foot-trefoil to thrive.

What if You ‘Only’ Get Long Grass?

If you leave your lawn to do its thing, it’s going to look stunning no matter what comes through – nature is great like that.

Wildflowers are stunning and they’re certainly a favourite for our pollinators – but our gorgeous grasses often get left out of the spotlight.

When your grass is getting longer, take some time to sit out, watch the sun shining through the blades and the wind whisper through it.

Also, did you know that our native grasses are great for nature? Keep an eye out for the incredible Cock’s-foot Grass for example. It’s one of our tallest lawn grasses and can reach more than 1 metre. It provides pollen that honeybees love, caterpillars eat its leaves, finches feed on its seed and its tussocks provide safe places for nesting mammals and bees.

Yellow Rattle: The Meadow Maker

Yellow Rattle: The Meadow Maker

Yellow Rattle, is the single most important plant you need when creating a wildflower meadow. Here’s everything you need to know.

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!  

 

In Spring and Summer 

Long cut grass in a wheelbarrow on a garden lawn
  • Avoid using herbicides, fertilizers and moss killers  as these are detrimental to wildflower species.
  • Allow plants time to go to seed before cutting your lawn so they increase naturally.    
  • Remove grass cuttings to prevent nutrient build-up in your lawn which might discourage wildflowers to grow. 

In Autumn

  • Introduce Yellow Rattle – known as ‘the Meadow Maker’ – to long-grass areas as it reduces growth of competitive grasses giving wildflowers more space to grow.  Here’s our comprehensive guide to growing yellow rattle. 
  • Introduce native, meadow plug plants, preferably in the autumn. Choose suitable perennials such as Cowslips, Bird’s-foot Trefoil, Betony, Oxeye Daisy, Selfheal and Knapweed. You may need to help them establish in the first couple of years, ensuring they don’t get crowded out by the grasses.  
  • Sow native flower seed in patches of prepared soil in the autumn. Remove the top few centimetres of turf from a small area, break up the soil a little with a fork and sprinkle the seed in the patch. Keep well-watered if the soil is dry until the plants are established. Read more in our guide here.

Don’t forget that humble dandelions and daisies are fantastic lawn flowers!

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.

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.

Photographing showing the lifecycle of Yellow Rattle - on the left hand side is a Yellow Rattle plant in flower, with it's pretty and unusual yellow flower heads in focus, in the centre there is a Yellow Rattle plant that has began to set seed with green seed pods visible, on the right hand side there is a Yellow Rattle plant in seed where the pods have dried.

What is the Life Cycle (a year) of Yellow Rattle?

  • The seeds germinate in early spring and grow quickly
  • As the roots develop, it seeks out the roots of plants growing nearby, especially grasses
  • Once it makes contact, Yellow Rattle draws water and nutrients from the nearby plants
  • This leaves space for flowers to grow

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.

How to Grow Yellow Rattle?

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:

When Does Yellow Rattle Seed and How Can You Harvest Yellow Rattle Seed?

  • Yellow Rattle seeds are very short lived so they must be sown as fresh as possible and ideally will have been harvested in the most recent summer
  • You can pop over to the Plantlife shop to buy some
  • Or even better, if you know somewhere locally with Yellow Rattle, then ask if you can collect some seed
  • Seeds are collected by picking the stems (on a dry day) and shaking them into a paper bag
  • The seeds must be collected between June and August – once ripe they will begin to fall to the ground so there’s only a short window of opportunity! Ripeness is dependent on the summer weather and is likely to be soonest in the warmest parts of the country such as the south east.

How to Sow Yellow Rattle Seed?

  • Firstly, you must prepare the area – cut the grass as short as you can between July and September and remove the clippings
  • There may be a layer of dead grass, which should be removed by raking through the area with a soil rake, to expose some bare soil throughout – this is crucial so the seed can reach the surface of the soil, and won’t be choked as a seedling
  • The seeds can then be sown by hand by scattering
  • This needs to be done by November at the latest, because the seeds need about 4 months below 5C to germinate in the spring

When Will Yellow Rattle Germinate?

  • Seedlings will start to appear in the spring, from as early as late February. But there is no need to worry if only a few plants germinate in the first year as they will shed seed and numbers should rapidly increase
  • The wildflower meadow should be cut once the Yellow Rattle has shed its seed – between July and August. Cutting times will vary depending on where you live and the seasons
  • In a garden, cutting the grass and removing the clippings once or twice before December ensures Yellow Rattle has the space to germinate and grow by February

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.

FAQ

  • 1. When should I sow Yellow Rattle?

    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.

  • 2. How do I collect my own Yellow Rattle seed?

    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.

    WATCH: Plantlife’s Sarah Shuttleworth collects Yellow Rattle with a vacuum. 

  • 3. Why has Yellow Rattle disappeared from my meadow?

    There are a number of reasons why Yellow Rattle may disappear from a meadow, including:

    • Cutting before the rattle has set seed
    • Leaving the cuttings on the meadow
    • Grazing in early spring when the seedlings are out and vulnerable
    • The meadow is too fertile
    • Grass is out-competing the Yellow Rattle
  • 4. How much Yellow Rattle should I sow?

    For meadows, we recommend 0.5-2.5kg per hectare/10-20g per m2 if you are collecting your own seed.

  • 5. Why hasn’t my Yellow Rattle geminated?

    There are several possible reasons:

    • The seeds were more than a year old (we advise buying from a reputable supplier).
    • Not enough bare ground was created before sowing. It is best to create at least 50% bare ground.
    • The meadow was too fertile and the grasses out competed the rattle.
    • Rattle was sown at the wrong time of year (sowing in the late summer is best). If sown in the spring it should have been stored damp mixed with sand at 4C for 6 –12 weeks.
    • The grass was too long in the early spring, when the rattle germinates. Cutting the meadow in February and removing the clippings can help. This gives the rattle seedlings a better head-start when competing for light with the surrounding grasses.

What is a Weed? And Why Wildflowers Aren’t Weeds

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.

A close up of a pretty yellow flower against a background of blurred grass.There are five main flower heads in the shot and on the one closest to the camera is a bright green insects shining in the sun.

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’. 

Common Wasp Queen on a Dandelion

What is a Weed? 

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. 

A bright purple Thistle flower head is pictured in front of a large arable field growing crops

Where Did ‘Weeds’ Come From? 

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. 

What About Non-Native Invasive Plant Species in the UK?

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.

What About Problem Plants? 

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. 

Rethinking the Weed 

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.

No lawn? No Problem: 6 Ways to Join in with No Mow May

As well as bringing back the bloom to our lawns, there are many ways you can get involved with No Mow May, even if you don’t have a garden.

  • Go to:

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.

Different Grass Lengths

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.

Let it Grow…

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 muchYou will be providing vital protection for toads and voles while seedheads will act as natural bird feeders for visiting finches.  

How to Mow (if you need to)

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.

Collect Your Cuttings

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. 

Watch Out for Wildlife

Some wildlife may have taken refuge in your liberated lawn. Here are some quick tips for keeping wildlife safe while you mow:

  • Hand search areas of longer grass for small mammals , like hedgehogs, before you begin the cutting process.
  • Work gradually parallel to the shelter 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.
  • 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.

Your Choice…

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.

As well as bringing back the bloom to our lawns, there are many ways you can get involved with No Mow May, even if you don’t have a garden.

Why Did You Want to Start the No Mow Movement?

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.

What Difference has it Made?

To the Wildflowers and Grasses?

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.

To Insect Biodiversity?

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.

And the People?

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.

What Does No Mow May Look Like at the Museum?

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.

Where are you Doing No Mow May?

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.

 

What Wildlife have you Seen?

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:

  • Moths – Cinnabar Moths, Burnet Moths and Poplar Hawk-moths
  • Butterflies – Small Skipper Butterly and Wall Brown
  • Bees – Red Mason bees and Cuckoo bees.
  • Wasps – Jewel Wasps and some different parasitic wasps (every year we record more of those)
  • Shield Bugs – Parent bugs and Hairy Shield bugs
  • Other bugs – Ladybirds and ground beetles

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.

Why Does the No Mow Movement Matter?

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.
