Encouraging Hedgehogs into a Small Urban Garden

Why a Small Garden Matters More Than You Think

Hedgehogs have been vanishing from the British countryside at an alarming rate. Numbers are thought to have fallen by well over half since the turn of the century, with intensive farming, tidy boundaries and busy roads all taking their toll. Yet in the middle of that bleak picture sits a quiet piece of good news: urban and suburban gardens have become one of the species' strongest refuges. A single garden is too small to matter on its own. A street of connected gardens, however, becomes a landscape — and that is something a hedgehog can actually live in.

If you have a modest patch of grass, a bit of paving and a fence, you already have the raw materials. What follows is not rewilding on a grand scale. It is a handful of small, deliberate choices that turn a garden from an obstacle course into a place where a nocturnal visitor can feed, rest and safely move on.

Build a Hedgehog Highway

Hedgehogs are wanderers. A single animal may travel a mile or more in a night, and a solid fence line stops it as surely as a wall stops you. The fix is almost embarrassingly simple: a gap.

• Cut a square roughly 13cm by 13cm (about the size of a CD case) at the base of a fence panel or gate — a hedgehog will happily use anything it can push its nose through.
• If you cannot cut the panel, simply lift the gravel board so the gap sits underneath, or raise the bottom edge of a gate by a brick's height.
• Gaps work best when they line up with your neighbours'. A quiet word over the fence about matching positions can open up a whole terrace in an afternoon.
• Mark your gap with a small stone or plant marker if you like, but avoid anything that creates a step — hedgehogs dislike climbing.

If your garden is fully walled, a short length of pipe or a purpose-made tunnel set into the base of the wall under a few bricks does the same job. Once the route is open, leave it open. A gap blocked in summer is a dead end in autumn, when animals are searching hardest for a place to hibernate.

Leave a Wild Corner (and Mean It)

The tidiest gardens are the least useful. A hedgehog needs somewhere to sleep through the day and somewhere to hibernate through the winter, and both require a certain amount of mess that most of us have been trained to clear away.

• A log pile in a shaded corner, stacked loosely with the odd gap, offers shelter and attracts the beetles and grubs that make up much of a hedgehog's diet.
• Leaf litter and twig bundles left under shrubs from autumn onwards are ideal hibernation material. Resist the urge to clear them in February.
• A compost heap is a hedgehog magnet — warm, damp and full of invertebrates. Do check before you turn it, and always fork gently rather than plunging a spade in.
• Long grass and native planting around the edges give cover for foraging and travelling, so a hedgehog can cross your garden without running a gauntlet of open lawn.

Crucially, go chemical-free. Slug pellets are lethal to hedgehogs, whether eaten directly or taken in through poisoned slugs. The same applies to rat poison and most weedkillers. If slugs are your enemy, let the hedgehog be your answer — a single animal can take a hundred or more invertebrates in a night.

Offer Water, and Food Only as a Top-Up

A hedgehog's natural larder of beetles, caterpillars and earthworms usually provides enough. In dry summers, or during the lean weeks of autumn, a little extra helps — but the most important thing you can put out is water.

Use a shallow dish no more than two or three centimetres deep, with a few small stones inside so an animal can climb out if it slips. A saucer sunk level with the soil works beautifully. Refill it every evening in warm weather; a dehydrated hedgehog is a hedgehog in trouble.

If you do feed, keep it simple and appropriate:

• Meaty cat or dog food in jelly or gravy is fine — avoid fish flavours.
• Kitten biscuits crushed slightly are a useful dry option.
• Mealworms only occasionally — fed in quantity they can upset calcium balance.
• Never milk and never bread. Hedgehogs are lactose intolerant, and both do real harm.

Put food out after dusk, close to cover, and take leftovers in each morning so you are not feeding foxes, cats or rats instead.

Make the Garden Safe After Dark

Most hedgehog injuries happen in gardens, and almost all of them are preventable with a little foresight.

• Ponds need an escape route. A gently sloping edge or a half-submerged stone lets a hedgehog climb out; vertical sides do not.
• Check before you cut. Strimmers, mowers and hedge trimmers cause terrible injuries. Walk the long grass first and look before you start.
• Bonfires: build the pile on the day you plan to light it, or move it completely. A heap of dry wood is a five-star hedgehog bed.
• Netting: roll up sports nets, fruit netting and pea netting at night, and keep it well above ground level.

If you find a hedgehog out in daylight, it is almost certainly unwell. Do not treat it yourself — place it in a ventilated box with a towel and a shallow dish of water, keep it warm and quiet, and contact a local wildlife rescue for advice.

The Quiet Reward of Slowing Down

None of this requires money, machinery or a degree in ecology. It requires patience and a willingness to leave well alone. Let the leaves lie where they fall until spring. Let one corner grow shaggy. Sit outside at dusk in late summer with a mug of something warm and simply listen. The snuffling, shuffling sound of a hedgehog working its way along a border is one of the great small pleasures of a British garden — and it only happens when we stop tidying long enough to let it.

Think of your garden not as a finished thing but as a link in a chain. Yours joins to your neighbour's, and theirs to the next, and somewhere at the end of it a hedgehog finds a safe place to sleep. That is slow nature living at its most practical, and it starts with a gap in the fence.
