Why Hedgehogs Need Our Help

Hedgehogs are one of our most beloved garden visitors, yet their numbers have fallen sharply in recent decades. The reasons are many: tidy gardens, fewer hedgerows, busy roads and the loss of the wild, messy corners where they once thrived. The good news is that even a small urban or suburban plot can become a genuine refuge. You do not need acres of countryside. A modest garden, thoughtfully arranged, can offer a hedgehog everything it needs: food, water, shelter and safe passage.

The hedgehog's year is a cycle of foraging, breeding and hibernation, and each season brings different demands. In spring and summer they roam widely in search of beetles, caterpillars, slugs and earthworms. By autumn they must build up fat reserves for winter, and from roughly November to March many will hibernate in a snug nest of leaves and moss. If your garden can support them through all of these phases, you will be doing real conservation work from your own back door.

Opening Up Safe Passage

One of the most valuable things you can do is simply let hedgehogs in. A hedgehog may travel a mile or more in a single night, but it cannot climb walls or fences. A solid boundary turns your garden into a trap rather than a home, cutting animals off from mates and food.

The solution is a hedgehog hole, sometimes called a hedgehog highway. A gap of around 13 centimetres (roughly five inches) square is ideal; large enough for a hedgehog to pass through, small enough to discourage most pets. You can cut a notch in the base of a fence panel, lift a gravel board, or dig a small tunnel beneath a gate. If you share boundaries with neighbours, talk to them about linking holes together. A connected row of gardens becomes a genuine corridor.

Check the positioning carefully. Place holes low to the ground and clear of obstacles, and avoid anywhere that opens directly onto a road.

Water, Food and What to Avoid

Hedgehogs are thirsty creatures, and a shallow dish of fresh water is one of the simplest gifts you can offer. Use a dish no deeper than about two to three centimetres, or add a few pebbles so that if a hedgehog tumbles in, it can climb out. Never leave out milk, which causes digestive upset, and avoid bread.

A shallow dish of meaty cat or dog food, or specific hedgehog food, is a helpful supplement, particularly in dry spells when natural prey is scarce. Place it in the evening and remove anything uneaten by morning to avoid attracting rats. Remember that supplementary feeding supports hedgehogs but does not replace a healthy, insect-rich garden.

• Do leave a shallow water dish out all year, topping it up daily in hot weather.
• Do offer meaty cat or dog food in jelly, or a purpose-made hedgehog food, in the evening.
• Don't put out milk, bread or fish-based foods.
• Don't use slug pellets or other pesticides, which poison hedgehogs directly and remove their prey.
• Don't use strimmers or check long grass without looking first; hedgehogs often rest in exactly those spots.

Building a Sheltered Corner

Hedgehogs need somewhere quiet, dry and snug to nest and hibernate. A wild, undisturbed corner is perfect: a heap of leaves, a pile of logs, or a bundle of twigs left to rot down naturally. These piles also harbour the beetles and grubs that make up a hedgehog's diet, so they are working doubly hard for you.

If your garden is small and every corner is spoken for, a purpose-built hedgehog house can fill the gap. Site it in a shady, sheltered spot, facing away from the prevailing wind, and cover it with a layer of dry leaves for insulation. Resist the urge to tidy around it; hedgehogs are easily disturbed and may abandon a nest if it is repeatedly uncovered.

Autumn is the critical time. From October onwards, leave leaf litter in place rather than sweeping it all away. A generous mulch of leaves beneath a hedge or shrub provides both bedding and foraging ground. If you find a hedgehog out in the day during cold weather, it is often a sign of trouble, and it is worth seeking advice from a local wildlife rescue.

A Garden That Gives Back

The gentle art of making a garden hedgehog-friendly is really the art of letting go a little. Leave a patch of long grass. Allow a few nettles to stand. Let leaves gather under the shrubs. Plant native species such as hawthorn, honeysuckle or wild cherry where you can, and avoid the temptation to make everything immaculate.

In return you gain far more than the pleasure of a prickly visitor snuffling about at dusk. A garden with a little wildness in it hums with life: moths, beetles, frogs and birds all benefit from the same changes that suit hedgehogs. You are not just tidying less; you are building a small, thriving habitat. And there is something quietly wonderful about knowing that, through a hole in your fence and a dish of water, you have given one of Britain's most endearing creatures a fighting chance.
