Making a Hedgehog Friendly Corner in Your Garden

Why Hedgehogs Need a Hand

Hedgehogs were once a familiar sight snuffling about British gardens after dusk, but their numbers have fallen sharply in recent decades. The reasons are many and tangled together: tidier gardens, sealed boundaries, busier roads, and fewer of the wild, messy corners where these little mammals find food and shelter. The good news is that a garden is not a lost cause. In fact, ordinary gardens and community growing spaces are now some of the most important hedgehog habitat we have left, and a few small, deliberate changes can turn a neat plot into a genuine refuge.

You do not need acres of land or a wildlife diploma. Hedgehogs are undemanding guests. Give them a way in, somewhere to sleep, a drink, and a supply of insects, and they will do the rest. What follows is a practical guide to creating a hedgehog friendly corner, whether you tend a small back garden, an allotment, or a shared community plot.

Let One Corner Grow Wild

The single most valuable thing you can offer is a patch of untidiness. Hedgehogs are foragers, not grazers, and they spend their nights hunting beetles, caterpillars, slugs, earwigs, and worms. A close-mown lawn and bare borders support very little of that larder. A wild corner, left to its own devices, becomes a small ecosystem that feeds them night after night.

Choose a spot that is out of the way, perhaps behind a shed or along a north-facing fence, and simply stop managing it. Allow the grass to grow long, let self-seeded wildflowers come up, and leave fallen leaves to settle. A few specific additions will help:

• Long grass and native wildflowers such as foxgloves, knapweed, and bird's-foot trefoil, which attract the insects hedgehogs eat.
• A log pile or brash heap left in a quiet corner, which shelters beetles, slugs, and the hedgehogs themselves.
• A compost heap kept open at ground level, a favourite daytime resting place for a tired hedgehog.
• Leaf litter raked into a mound rather than bagged up, providing warmth and invertebrate cover.

Avoid cutting this area between November and March. If you must tidy it, do so gently and by hand, checking for sleeping animals before you move anything.

Open Up the Fence Line

Hedgehogs can travel a mile or more in a single night in search of food and mates, but a solid fence or wall stops them dead. A hedgehog cannot climb, and it will not tunnel under a concrete gravel board. This is why connected gardens matter so much: a hedgehog needs to roam across a whole neighbourhood, not be trapped in one plot.

The fix is delightfully simple. Cut a gap roughly 13 centimetres square, about the size of a CD case, at the base of your fence or wall. That is large enough for a hedgehog to pass through comfortably but too small for most pets to escape. If you share a boundary, talk to your neighbour and cut a matching gap on both sides. On an allotment or community site, a few deliberately placed gaps can link dozens of plots into a single, generous foraging route.

If a gap is not possible, a hedgehog highway can sometimes be created with a short tunnel beneath a gate, or by replacing a section of gravel board with a length of pipe laid at ground level. Every connection counts.

Offer Water and a Little Food

Hedgehogs are often desperately thirsty, especially in hot, dry spells and in late autumn when they are trying to put on weight before hibernation. A shallow dish of fresh water, refreshed daily, is one of the kindest things you can provide. Keep it low-sided so that a small animal can reach the water without falling in, and place it in the wild corner rather than out in the open.

If you choose to offer food, keep it simple and safe:

• Meat-based cat or dog food in jelly, not gravy, is a good standby.
• Specialist hedgehog food is widely available and well balanced.
• Never give milk or bread, which cause serious digestive problems in hedgehogs.
• Clear leftovers each morning to avoid attracting rats and foxes.

A shallow dish of water is the priority. Food is a helpful extra, particularly for a hedgehog that appears underweight or is out in daylight, which is often a sign of trouble.

Make the Garden Safer After Dark

A welcoming garden can still be a hazardous one if the details are overlooked. Hedgehogs are nocturnal wanderers with poor eyesight close up, and the everyday tools of gardening can become traps. A few habits will make your plot far safer:

• Check before strimming or mowing, especially long grass and the edges of the wild corner.
• Cover drains and ponds with a gently sloping ramp or a mesh grid so that any animal that falls in can climb out.
• Leave netting raised at least 30 centimetres above the ground, and never leave it lying loose overnight.
• Store slug pellets and other chemicals away, or better still avoid them entirely, as poisoned slugs are eaten by hedgehogs.
• Check bonfires before lighting, and move the pile on the day rather than building it in advance.

These are small adjustments, but they make the difference between a garden that is merely visited and one that is genuinely safe.

A Shelter for Sleeping and Hibernating

Hedgehogs need somewhere dry and sheltered to rest during the day and to hibernate through the winter. A purpose-built hedgehog house is a good addition, but it must be sited thoughtfully. Place it in a quiet, shaded spot, facing away from prevailing wind and rain, and cover the roof with a layer of dry leaves or a piece of turf to insulate it. Do not lift the lid between November and April, as you may disturb a hibernating resident.

If you would rather not buy a house, a simple homemade alternative works well: a stout wooden box with a 13 centimetre entrance tunnel, or a sheltered space beneath a shed or decking. Keep a pile of dry leaves and hay nearby for bedding. Above all, leave the wild corner undisturbed. A hedgehog's best shelter is often the one you did not build, the quiet tangle of grass, logs, and leaves that nobody has touched for a year.

Do all of this, and your garden stops being a passing point and becomes part of a living network. A gap in the fence, a dish of water, a corner left alone: these are the small acts that keep hedgehogs shuffling through our neighbourhoods long after the sun has gone down.
