Why a Small Garden Matters

Hedgehogs have been declining sharply across Britain in recent decades, and the reasons are rarely dramatic. It is the quiet losses that add up: a fence panel replaced with a concrete gravel board, a bed of nettles dug out for paving, a pond filled in. For a creature that can travel over a mile in a single night, a small town garden can be an important stepping stone — or a dead end. The good news is that even a modest plot, perhaps a courtyard or a narrow strip behind a terraced house, can become genuinely useful to a hedgehog with a few deliberate choices. You do not need acres. You need a wild corner, a shallow dish of water, and a way through the fence.

Leave a Wild Corner

The single most valuable thing you can do is to stop tidying one section of the garden. Choose the least visible corner — behind a shed, beside a compost heap, under a hedge — and let it go. Hedgehogs are nocturnal foragers that feel exposed in open, manicured space, and they need somewhere to sleep through the day. A messy corner provides both.

• Allow leaf litter to accumulate. A pile of leaves is warm, damp and full of beetles and slugs. It is also an ideal nesting material.
• Resist cutting back nettles and brambles completely. A patch of nettles supports the caterpillars and beetles that hedgehogs eat.
• Leave a log pile. Stacked wood, especially partly buried in soil, shelters beetles, millipedes and the occasional frog. Hedgehogs will root around its edges at night.
• Build a leaf mound or a purpose-made hedgehog house. A simple wooden box with a tunnel entrance, filled with dry leaves, sited in shade and facing away from prevailing wind, makes an excellent day nest.
• Avoid strimming long grass until you have checked it thoroughly. Hedgehogs rest in exactly the sort of cover a strimmer destroys.

If your wild corner looks a little untidy, that is the point. Think of it as habitat rather than neglect.

Provide Shallow Water

Hedgehogs get thirsty, particularly in dry spells and after hibernation, and they cannot drink from a steep-sided bird bath or a raised pond. They will drown in water they cannot climb out of — a regular and preventable cause of death in gardens.

Set out a shallow dish at ground level, no more than 5cm deep, and refresh it daily in warm weather. An old saucer, a plant pot base or a low ceramic bowl all work. Place it near your wild corner or along a route you have seen a hedgehog use. If you keep a pond, add a gentle ramp of stones or a piece of roughened wood at one edge so anything that falls in can climb back out. Check the ramp stays put through winter rain.

Avoid milk. It causes digestive upset in hedgehogs, and the old saucer-of-bread-and-milk tradition is genuinely harmful.

Make a Hedgehog Highway

A garden with no exit is a trap. Hedgehogs roam widely, and a solid fence line cuts off foraging routes that may have been used for generations. The fix is a gap roughly the size of a CD case — about 13cm square — at ground level in each boundary.

• Cut a hole in a wooden fence panel at the base, or lift a gravel board slightly to create a tunnel underneath.
• For concrete or brick walls, remove a single brick at ground level and leave the gap open.
• For hedges, check the base is not blocked by a solid panel or a build-up of soil.
• Talk to your neighbours. A coordinated row of gaps along a street creates a genuine corridor, and most people are happy to help once they understand why.

Mark the gaps subtly so you do not block them later with a pot or a bag of compost. Hedgehogs are creatures of habit; once a route is open, they will use it nightly.

Supplement Wisely

Feeding is optional but rewarding, and it can help hedgehogs through lean periods in late autumn. Offer food after dusk and remove anything left by morning, so you do not attract rats or foxes.

• Meat-based cat or dog food in jelly, never in gravy, is ideal.
• Dry cat biscuits are useful in small quantities and are less messy.
• Chopped unsalted nuts or mealworms in moderation only — mealworms are low in calcium and should not form the bulk of the diet.
• Never offer bread, milk, or anything salty or sugary.

Put the food under a weighted bowl or a purpose-built feeding station with a narrow entrance. This keeps cats and foxes out and gives the hedgehog a calm meal.

Keep the Garden Safe Year-Round

Small changes protect your nightly visitors from the hazards that a tidy garden presents. Check your slug pellet packaging and switch to wildlife-friendly alternatives — metaldehyde and ferric phosphate products are a serious risk to hedgehogs. Cover drains and any steep-sided hole. Before lighting a bonfire, move the pile on the day and check underneath, because a dry heap is an irresistible hibernation site. If you use a robotic mower, run it in daylight only. Autumn is the time to leave your wild corner alone entirely. From October onwards, hedgehogs are seeking hibernation spots, and a disturbed leaf pile or turned compost heap can rouse one at a point when its fat reserves cannot be rebuilt. By spring, you may be rewarded with the rustle of a hedgehog emerging from the border at dusk — proof that a small town garden, with a wild corner, a shallow dish and a gap in the fence, is doing its quiet part.
