Attracting Hedgehogs to a Suburban Garden

Hedgehogs are in trouble across Britain, and the suburban garden has quietly become one of their most important refuges. Helping them needs no grand plan — just a few thoughtful changes, a little untidiness, and the willingness to look before you cut.

Why Hedgehogs Need Suburban Gardens

Hedgehog numbers have fallen steeply since the turn of the century. In the countryside, larger fields, fewer hedgerows and heavier pesticide use have stripped away both food and cover. In towns the pressures differ but are just as serious: solid fences, decking, busy roads and gardens kept too neat to shelter anything.

That is why suburban plots matter so much. A hedgehog needs three things from your garden — somewhere dry and hidden to sleep through the day, a reliable supply of beetles, slugs and caterpillars at night, and a safe route in and out. Get those three right and the same animal may well return night after night.

Leave a Wild Corner

The single most valuable thing you can do is to stop tidying one corner of the garden. A patch roughly a metre square, left to grow long and topped up with leaf litter, offers daytime cover that a mown lawn cannot. South-facing is ideal, since it stays warmer and drains well.

A good wild corner might hold:

• long grass and native wildflowers such as knapweed or foxglove;
• a loose pile of logs and prunings, with the gaps left open;
• a shallow heap of leaves, which doubles as nesting material;
• a few nettles or brambles, if you have the space.

Hedgehogs hibernate from roughly November to March, often in a leaf pile, compost heap or beneath a shed, so leave the corner undisturbed right through the winter. Cutting it back in autumn is the surest way to lose a resident.

Create a Hedgehog Highway

A hedgehog can travel up to two kilometres in a night, but a solid fence stops it dead. The fix is simple: a gap about 13 centimetres square at the base of a fence or wall, or beneath a gate. That is small enough to keep most pets in and large enough for a hedgehog to pass comfortably.

Worth doing:

• lift gates slightly or leave a corner open;
• cut a notch in gravel boards, or leave one panel short;
• add a gentle ramp at the edge of any pond, so an animal that falls in can climb out;
• keep low netting off the ground, or check it every morning.

Better still, talk to your neighbours. A run of connecting gardens becomes a proper corridor, and hedgehogs will use it far more than an isolated plot.

Water, Food and the Slug Pellet Question

Water is the most underrated kindness. A shallow dish — no more than two or three centimetres deep — gives a hedgehog what it needs to drink, especially in hot weather. Put a few pebbles or a small stone ramp inside so anything that falls in can climb out. Keep it topped up all year, including mild spells in winter when hibernating animals may briefly wake.

If you want to offer food, use meat-based cat or dog food or specialist hedgehog biscuits, in a shallow dish well away from the house. Never put out milk or bread: milk causes diarrhoea and bread has no useful nutrition. Mealworms are fine now and then but should not form the bulk of the diet, as they are low in calcium.

Slug pellets are the one thing to rule out completely. Whether they contain metaldehyde or ferric phosphate, they either poison hedgehogs directly or remove the slugs and beetles they depend on. Hand-picking after dark, beer traps sunk into the soil, or a biological nematode treatment will do the job without harming anything with a spine.

Check Before You Strim or Light a Bonfire

Long grass and brambles are exactly where a hedgehog wants to sleep, which makes strimmers and brushcutters genuinely dangerous. Before you start, walk the area and disturb it — a rake handle or a gentle rustle of the undergrowth is usually enough. Cut the first pass high and work outwards from the centre, giving anything hidden a chance to move.

Bonfires deserve the same caution. A pile of wood left standing for a week is a five-star hedgehog nest. Build the fire on the day you plan to light it, or move the pile a metre or two and check it carefully before striking a match. Take similar care with compost heaps and log stacks, and never plunge a fork in without a quick look first.

If you do find an injured animal, place it in a dark, ventilated box with a towel, keep it warm, and contact your local wildlife rescue straight away.

A Gentle Year-Round Routine

None of this needs to be complicated. A little rhythm is all it takes:

• Spring: leave nesting cover alone, keep the water dish full, and hold off strimming until you have checked.
• Summer: top up water daily in hot spells, watch for hoglets out in daylight, and leave the wild corner untouched.
• Autumn: sweep leaves into the corner rather than bagging them, and check bonfire piles and compost heaps.
• Winter: disturb as little as possible, and keep food and water available during mild spells.

A garden that is a little rough around the edges is often the richest one. Leave the corner, skip the pellets, put out a saucer of water, and look before you strim — and one evening, just after dusk, you may see that unmistakable snuffling shape crossing the lawn.
