How to Create a Wildflower Lawn

A wildflower lawn brings a little bit of the old British countryside back to your garden. Flower-rich meadows have become rare, but any patch of lawn can help bring them back.

It’s not quite the same as letting the grass grow long. You need poor soil, the right seed and a simple mowing routine. It takes patience, but once it’s going, a meadow patch is less work than a lawn and full of life. For more ways to help wildlife, see our guides to bee-friendly plants and attracting birds.

Why do wildflowers need poor soil?

Rich soil feeds the grass, and the grass smothers the flowers. Meadow flowers are used to thin, poor ground. On poor soil the grass grows weakly, leaving gaps where wildflowers can get going.

Most lawns sit on soil that’s been fed for years. That’s the main reason wildflower seed fails in gardens. So before you sow, you need to make the soil poorer. It feels odd if you’ve spent years adding compost, but making a meadow is the opposite job.

Signs your soil is too rich: dark crumbly soil, thick lush grass, and nettles, docks or lots of clover. If dandelions, buttercups and self-heal already grow in your lawn, it may be lean enough already.

How to prepare the ground for a wildflower lawn

Make the soil poorer and give the seed some bare earth. You can strip the turf, or convert the lawn slowly.

Starting on bare ground

Strip off the turf about 5cm deep with a turf cutter or a sharp spade. This takes away the richest soil along with grass roots and weed seeds. If the soil underneath still looks dark and rich, take off a bit more.

Rake to a fine, crumbly surface and pick out bigger stones. Firm the soil by treading over it, then rake lightly again. Aim for level and crumbly, not packed hard.

Converting an existing lawn

Stripping the turf is the surest way, but you can convert a lawn in place over two or three years. Stop feeding straight away. Mow regularly through the first summer and always take the clippings away. Each time you do, you take goodness out of the soil.

In autumn, rake the lawn hard with a spring-tine rake or a powered scarifier. You want lots of bare soil so seed can touch the earth. It’ll look rough, and that’s the point. Sow yellow rattle into the scratched patches in September or October.

It looks rough, and that’s exactly what you want. Seed needs to land on bare soil to get going, so scratch until about half the lawn shows earth.

What is yellow rattle and why does it matter?

Yellow rattle is the most important plant for making a meadow. It feeds off grass roots, which weakens the grass. The RHS guide to wildflower meadows explains why it’s sown into lawns being converted.

Weaker grass leaves space for other wildflowers. Without yellow rattle, grass tends to win. With it, the flowers get a chance.

The seed doesn’t keep, so always buy fresh seed from this year’s harvest. Sow it from September to November, because it needs a cold winter to sprout. Spring-sown yellow rattle rarely comes up.

Scatter about 1g per square metre onto bare or scratched soil. Press it in by treading or rolling, but don’t cover it. It sprouts in March and April and flowers in May and June. By July the seed pods rattle when you shake them, hence the name. Our flower planting calendar has sowing times for other flowers too.

Yellow rattle feeds off grass roots and weakens the grass, which gives other wildflowers room. Once the pods dry and rattle in July, it has set seed.

Which wildflower seed mix should I choose?

A wildflower lawn in summer, full of oxeye daisies, buttercups, red clover and poppies.

Pick a perennial meadow mix for a lasting sunny meadow, cornfield annuals for quick colour, or a shade mix under trees.

Perennial meadow mix: the long-term choice

This is the classic meadow. Native grasses and wildflowers that take two or three years to settle in, then carry on for years with one cut a year. Look for:

• Oxeye daisy: the big white meadow daisy, flowering from May
• Common knapweed: purple, thistle-like flowers, a favourite with bees and butterflies
• Field scabious: lilac pincushion flowers that bees love
• Cowslip: nodding yellow flowers in April and May
• Red campion: pink flowers from May into late summer, happy in light shade
• Meadow buttercup: the tall buttercup of old hay meadows
• Bird’s-foot trefoil: little yellow pea flowers, food for the common blue butterfly

Cornfield annuals: instant colour

Want flowers in the first summer? Sow cornfield annuals. They grow fast, flower and set seed in one season, and cope with richer soil.

• Common poppy: scarlet flowers from June, comes up when soil is disturbed
• Cornflower: bright blue and easy to grow
• Corn marigold: cheerful yellow daisies
• Corncockle: elegant purple-pink flowers, now very rare in the wild

Sow them in spring at 3-5g per square metre. They flower in two or three months. Let them drop their seed, then clear the patch. Rake the soil the next spring to wake up the dropped seed.

How to sow wildflower seeds

Scattering seed by hand in autumn. Mixing it with silver sand helps spread it evenly.

Scatter the seed thinly on bare soil and press it in without covering it. The seed is tiny and needs to touch the soil.

Spring sowing (March to April)

Wait until the soil has warmed up a little. Mix the seed with dry silver sand, about one part seed to four parts sand. The sand shows you where you’ve sown and helps spread it evenly.

Sow 2-4g per square metre for perennial mixes. It looks like hardly any, but that’s right. Too much seed and the seedlings crowd each other out.

Scatter half walking one way across the patch, then the other half walking across it the other way. Press it in with a roller, a board or your feet. Don’t rake it in or cover it, as most wildflower seeds need light to sprout.

Autumn sowing (September to October)

Autumn suits perennial mixes and is a must for yellow rattle. The winter cold wakes the seed up naturally. Sow just the same way, and seedlings appear in March and April.

Should you use wildflower turf, plug plants or seed?

Seed is the cheapest and suits most gardens. Turf gives an instant result on small areas, and plug plants are the best way to add flowers to existing grass.

Wildflower turf is ready-grown meadow on a soil or felt base. You can lay it most of the year, but spring is best, and it needs plenty of water through its first summer. It costs far more than seed, so it’s mostly used for small spaces or green roofs.

Plug plants are young plants grown in little cells. They cope with grass much better than seed. Plant them in small groups of the same kind, in autumn or spring, into holes cut in short turf, and water until they settle. Knapweed, oxeye daisy, field scabious and bird’s-foot trefoil all do well this way.

Month-by-month wildflower meadow calendar

Most months need little or no work.

How to convert an existing lawn into a wildflower meadow

Make the soil poorer, sow yellow rattle, then add wildflowers. It takes two or three years.

Year one: reduce fertility

Stop all feed, weedkiller and moss killer. Keep mowing through the summer but always collect the clippings. This is the most important part.

In late summer or early autumn, scratch the lawn hard so at least half of it is bare soil. Sow yellow rattle into the scratched patches and press it in. Then add meadow sowing to your list of spring gardening jobs for next year.

Year two: introduce wildflowers

By spring the yellow rattle should be coming up and the grass looking thinner. Scratch it again in early March and sow a perennial meadow mix into the bare patches at 2-3g per square metre.

From May, stop mowing and let it all grow. Yellow rattle flowers in May and June, along with your first wildflowers. Cut once in late August or September and rake off everything.

Year three and beyond

The meadow gets richer every year. Wildflowers seed themselves into the gaps and the grass keeps weakening. By year three you should have a proper mix of flowers. Keep to the one cut a year, and always take the cuttings away.

Creating a small meadow patch

A mown path through the long grass makes the wild patch look planned and tidy.

Yes, a small lawn can have a wildflower patch. Even a strip a metre wide helps insects.

The unmown strip

The easiest way. Stop mowing a strip along a fence, wall or path, even just a metre wide. Daisies, clover, self-heal and dandelions will flower once the mower stops. Over time, scatter some wildflower seed in too.

The meadow island

Mark out a circle or oval in the lawn with sand or string. Prepare and sow it as a mini meadow, and mow around it as normal. Short grass next to long looks deliberate and smart. It suits cottage garden designs beautifully.

Mowing a crisp edge around a meadow island makes it look planned rather than forgotten. You still keep plenty of short grass for playing and sitting.

Container meadows

Fill big pots or troughs with mostly sharp sand and a little peat-free compost, which gives the poor soil wildflowers like. Sow cornfield annuals for quick colour or a perennial mix for longer. Stand them in full sun.

Can you just stop mowing to make a wildflower lawn?

Partly. Mowing less lets the flowers already in your lawn bloom, but on rich soil it won’t make a tall meadow. No Mow May is a good place to start, and a lawn with patches of different lengths holds the most flowers.

Try cutting part of the lawn short every month or so, with the clippings collected. Daisies, clover, self-heal and bird’s-foot trefoil will flower well, and you can still walk and sit on it. Leave other areas longer and cut them only two or three times a year, outside April to August, so taller flowers like oxeye daisy and knapweed can grow.

When you cut long grass, start in the middle and work outwards, or go from one side to the other. Mowing in from the edges can trap frogs, toads and small mammals.

Common mistakes when creating a wildflower meadow

Most meadows fail because of rich soil, mowing at the wrong time or old seed.

Sowing on fertile soil

The biggest reason meadows fail. On rich, dark soil, grass wins however much seed you sow. Strip the topsoil, or spend a year or two mowing and taking the clippings away first.

Not removing the cuttings

After the yearly cut, rake off the cuttings and take them away. Left to rot, they feed the soil and the grass. Leave them a few days for the seeds to drop, then rake.

Mowing at the wrong time

Cutting before late August chops the flowers down before they seed. Don’t mow from May to late August. But don’t skip the cut altogether, or coarse grass and brambles take over.

Using old yellow rattle seed

Yellow rattle seed must be fresh, from the last year’s harvest. Old seed hardly comes up. Check the date on the packet, and if there isn’t one, don’t buy it.

Sowing too thickly

Too much seed means crowded seedlings fighting each other. Stick to 2-4g per square metre and mix it with sand to spread it evenly.

Expecting instant results

A perennial meadow takes two or three years to look its best. The first year can look a bit scruffy. Sow some cornfield annuals if you want colour sooner.

Choosing non-native seed

Some cheap mixes contain non-native flowers. Buy seed labelled as native British origin. Oxeye daisy, knapweed and field scabious are the flowers our insects know best.

Native UK wildflower species guide

For sunny meadows, start with oxeye daisy, knapweed, field scabious and cowslip. For light shade, try red campion.

Full sun species

Oxeye daisy is the backbone of a sunny meadow. Big white daisies on tall stems from early summer. It seeds itself about and settles in fast. Happy on most soils except waterlogged ground.

Common knapweed has purple, thistle-like flowers from July to September. Butterflies, bees and hoverflies can’t get enough of it.

Field scabious has lilac pincushion flowers on wiry stems from July to September. Bumblebees and butterflies love it. It likes sun and well-drained soil.

Cowslip flowers early, with nodding yellow bells in April and May. It’s easy from seed in short grass.

Light shade species

Red campion has pink flowers from May into late summer. It’s happy in light shade, so it’s great for a patch near trees.

Greater knapweed is a bigger, showier version of common knapweed. It loves chalky and limestone soils and flowers from July to September, bringing in butterflies.

Grass species for meadow mixes

A meadow isn’t just flowers. Fine, gentle grasses fill the spaces between them. Look for these in a meadow mix:

• Common bent: fine and well-behaved
• Crested dog’s-tail: a classic meadow grass
• Sweet vernal grass: gives hay meadows their lovely scent
• Quaking grass: pretty seed heads that tremble in the breeze

Avoid coarse grasses like perennial ryegrass, which is far too pushy for wildflowers.

The annual mowing regime explained

One cut a year in late summer, with the cuttings taken away. That’s what makes a meadow, rather than just an untidy lawn.

When to cut

Cut once a year between late August and mid-September. By then most flowers have set seed. Earlier, and you lose the seed. Later, and coarse grass and nettles get the upper hand.

How to cut

Cut to 5-7cm. A rotary mower is fine for small patches. For bigger areas, a strimmer or a scythe is easier, and a scythe is quicker than you’d think once you get the knack.

What to do with the cuttings

Leave the cut stems on the ground for a few days so the seeds can fall. Then rake up every bit and take it away. Pop it on your compost heap or in the green waste bin.

Don’t skip this. Rotting cuttings feed the soil, which helps the grass and harms the flowers.

Leave the cut stems for a few days so the seeds drop, then rake up every bit. Taking the cuttings away keeps the soil lean, which is what the flowers need.

Optional spring mow

Some people give the meadow a second cut in March, down to about 5cm, before the spring growth starts. It keeps coarse grass in check and opens gaps for seedlings. It’s optional, but handy in the first few years.

Frequently asked questions

When is the best time to sow wildflower seeds?

March to April, or September to October. Autumn sowing gives many native seeds the winter chill they need to sprout. Spring suits cornfield annuals like poppies and cornflowers. In spring, wait until the soil has warmed a little.

Why do wildflowers fail on fertile soil?

Rich soil feeds the grass, and the grass smothers them. Meadow flowers are used to thin, poor ground. On rich soil, strip off the topsoil or grow cornfield annuals, which cope better. Taking the clippings away for a year or two also helps.

How often should I mow a wildflower meadow?

Once a year, in late August or September. Cut to 5-7cm. Leave the cuttings for a few days so the seeds drop, then rake them all off. This stops goodness going back into the soil.

What is yellow rattle and why is it important?

It’s a wildflower that weakens grass. Yellow rattle feeds off grass roots, which thins out the grass and leaves gaps for other flowers. Sow fresh seed in autumn, as it needs the winter cold to sprout.

Can I create a wildflower meadow on a small lawn?

Yes, even a tiny patch works. A small square, a strip along a fence or an unmown edge all help bees and butterflies. Start with one sunny patch and grow it each year. Big pots on a patio work too.

How long does a wildflower meadow take to establish?

Allow two to three years for the full show. The first year is mostly grass and a few quick flowers. More appear in year two. By year three you should have a lovely mix.

Do wildflower meadows attract bees and butterflies?

Yes, they’re brilliant for them. Bird’s-foot trefoil, knapweed, field scabious and oxeye daisy are all favourites. Meadows also help hoverflies, beetles and solitary bees. For more ideas, see our guide to bee-friendly garden plants.
