Summer: The Busiest Season in the Wildlife Garden

By the time July arrives, the garden is running at full tilt. Bees are working every open bloom from dawn until dusk, butterflies are drifting over the borders, and moths are taking over the night shift. It is easy to think of summer as a quiet, settled time, but for our pollinators it is the peak of the year — a frantic few weeks of feeding, nesting and laying eggs before autumn closes in.

The good news is that helping them does not require a rewrite of your whole garden. A handful of small, deliberate changes can turn an ordinary plot into a genuine refuge. Here is what genuinely makes a difference between June and September.

Let a Patch of Lawn Grow Long

If you do only one thing this summer, do this. A close-mown lawn is a green desert for wildlife: there is nothing to eat, nothing to shelter in and nowhere to nest. Letting even a modest patch grow long transforms it almost overnight.

Leave the mower in the shed for six to eight weeks and you will likely see self-heal, white clover, buttercups, dandelions and bird's-foot trefoil appear on their own. These are superb pollinator plants, and the clovers in particular fix nitrogen in the soil, feeding the lawn around them.

• Choose a patch that is easy to leave alone — a corner behind the shed, a strip along a fence, or the awkward slope you never enjoy mowing.
• Mow a path through it so the long grass looks intentional rather than neglected. A winding route adds real charm.
• Cut in late summer, ideally in September, and remove the clippings so the soil does not become too rich. This keeps the wildflowers coming back.
• Add yellow rattle in autumn if you want to push things further. It weakens vigorous grasses and lets wildflowers take hold.

Long grass also gives shelter to frogs, hedgehogs and the caterpillars of meadow butterflies, and its seed heads feed finches well into the winter.

Plant for a Long Season of Nectar

Pollinators need food from March to October, but summer is when demand peaks and natural sources in the wider countryside start to thin out. The trick is to aim for continuity, not just a single glorious flush in July.

Single, open flowers are far more useful than double blooms, whose petals often hide the nectar entirely. Think of the difference between a simple daisy and a tight pom-pom dahlia: one is a café, the other is a locked door.

• Early summer: catmint, salvia, alliums, foxgloves, thyme and hardy geraniums.
• Midsummer: lavender, marjoram, borage, betony, purple loosestrife and common knapweed.
• Late summer: hemp agrimony, verbena, heleniums, rudbeckia, sedum and asters.

Herbs earn their place in any border. Oregano and marjoram are magnets for solitary bees and hoverflies, and thyme is a favourite of the small tortoiseshell. Plant them in generous drifts rather than single specimens — pollinators navigate by sight and a bold block of colour is far easier to find than one lonely plant.

Do not forget the night shift. Moths pollinate a huge range of plants while we sleep, so add something pale and heavily scented near a window or seating area: night-scented stock, jasmine, honeysuckle or tobacco plant.

Put the Pesticides Away

This is the least glamorous advice in this article and the most important. A garden sprayed for aphids is a garden without food for ladybirds, hoverflies, blue tits and swifts — the very creatures that would have dealt with the aphids for free.

Slug pellets are a particular problem. Many contain metaldehyde, which is lethal to hedgehogs, birds and pets, and even the so-called organic iron phosphate versions can harm ground beetles. Try beer traps, night patrols with a torch, copper tape around pots, or simply accept a few holes in the hostas.

If you must tackle a pest, target it precisely with a jet of water, and leave the rest of the garden alone. A bit of untidiness and a few nibbled leaves are the small price of a living, working ecosystem.

Water, Shelter and a Place to Nest

Pollinators get thirsty, particularly in a hot spell, and a shallow dish of water with a few pebbles for landing is a small kindness that pays dividends. Refresh it every couple of days so it does not become a mosquito nursery.

Shelter matters just as much as food. A few logs in a shady corner, an undisturbed patch of leaf litter and a south-facing bank of bare earth will all be used by solitary bees and overwintering insects. If you are tidying, leave the seed heads on teasels, knapweed and grasses — they feed the birds long after the flowers have gone.

What to Watch For

Keep a notebook by the back door and jot down what you see. Over a summer you might record buff-tailed bumblebees on the lavender, a red admiral on the buddleia, a holly blue investigating the ivy and a hummingbird hawk-moth hovering at the verbena.

Those small records add up. Gardeners across Britain are quietly creating a patchwork of nectar-rich corridors, linking towns, villages and countryside in a way that no single reserve ever could. Start with one long patch of grass and one generous clump of flowers, and let the season do the rest.
