Why Hedgehogs Need Cottage Gardens

Hedgehogs have declined sharply across Britain in recent decades, and the reasons are mostly about habitat. Fields have been simplified, hedgerows removed and gardens sealed off with solid fencing, gravel boards and tidy paving. What survives is a patchwork of small, isolated green spaces where a hedgehog can find food but not a mate, or shelter but no safe route to water.

This is where the cottage garden earns its keep. A plot with a mixed hedge, a few unruly borders, a compost heap and a slightly neglected corner under a shrub is close to ideal hedgehog country. It offers cover, invertebrates, nesting material and shade. Add a way in and out, a dish of clean water and one or two deliberate shelters, and you can turn a single garden into a genuine refuge — and part of a network that stretches down the whole street.

Linking Your Garden to the Neighbourhood

A hedgehog will roam a kilometre or more in a single night, and its survival depends on being able to move between gardens without crossing a road. A solid fence is an effective wall. The remedy is simple, cheap and, in most gardens, invisible from the house.

• Cut a 13cm square gap at the base of each fence panel, or in the corner where two panels meet.
• Lift gravel boards by 13cm and support them on small blocks, which keeps the fence stable while opening a route beneath.
• Leave gaps under gates and check that gates do not sit flush to the ground.
• Plant a native hedge such as hawthorn, blackthorn or beech where a wall would otherwise be needed.
• Encourage the neighbours to do the same, ideally at matching points, so gardens become a joined-up corridor.

Keep the gaps clear of paving, gravel mounds and plant pots, and check them after heavy rain or leaf fall. A hedgehog highway is only useful if it stays open.

Making a Safe Nesting Corner

Hedgehogs need somewhere dry, quiet and undisturbed to sleep through the day and to hibernate from roughly November to March. A tidy garden offers very little. A wild corner offers everything.

Pile prunings and logs loosely in a shaded spot, leave a mound of fallen leaves undisturbed through winter, and keep one corner of the compost heap unpitched. These places provide both nesting material and the beetles, slugs and worms that make up most of the diet. If you would like a hedgehog house as well, choose a sturdy wooden one and site it facing north or east, out of direct sun, with the entrance tunnel at least 30cm long to deter cats and foxes. Place it against a wall or under a dense shrub, cover the roof with a layer of leaves or a piece of old slate, and then leave it alone. Hedgehogs abandon nests that are repeatedly inspected, so resist the urge to lift the lid.

Water, Ponds and the Ramp That Saves Lives

Every garden hedgehog needs water, and a pond is a magnet for wildlife — but a steep-sided pond is a death trap. Hedgehogs are competent swimmers and will happily cross open water, yet they cannot climb smooth butyl or plastic liner. They exhaust themselves against the side and drown.

Fit an escape route at one point in every pond: a rough wooden plank or a piece of slate, or a board wrapped in plastic mesh for grip, angled at no more than 45 degrees from the water surface to the bank. Check it is stable and that the submerged end reaches well below the waterline, so it still works in summer when levels drop.

Shallow water elsewhere is just as valuable. A sunken saucer or a heavy bowl filled to about 5cm, placed near a hedge or shelter, gives a safe drink. Refresh it daily, and add a few pebbles or a small ramp so nothing gets trapped. Never put out milk — hedgehogs are lactose intolerant and it causes serious digestive illness.

Feeding: What Helps and What Harms

Hedgehogs are insectivores, and the best thing you can do for them is to garden for invertebrates: leave a patch of long grass, avoid digging borders over in autumn, and let leaf litter accumulate. Supplemental food is useful in late autumn and during dry spells, but only the right sort.

• Offer meat-based cat or dog food in jelly, not gravy, and avoid fish flavours.
• Use a proper hedgehog food if you prefer a purpose-made option.
• Keep dried mealworms to a minimum. Fed in quantity they cause serious bone problems, particularly in young hedgehogs.
• Never leave bread, milk or leftovers. None of them suit a hedgehog's digestion.
• Put food under a weighted dish or a purpose-built feeder to keep cats, foxes and rats from clearing it first.

If you start feeding, keep going — hedgehogs quickly come to rely on a reliable supply, especially in autumn when they are building up fat reserves.

Everyday Hazards in a Rural Garden

A few small changes make the difference between a garden that welcomes hedgehogs and one that quietly kills them.

• Bin the slug pellets. Metaldehyde is banned for outdoor use and poisons hedgehogs directly; even iron-phosphate pellets remove their natural food and should be unnecessary in a balanced garden. Use nematodes, hand-picking or a beer trap instead, and let the frogs and thrushes do their work.
• Check before you cut. Strimmers and mowers cause terrible injuries. Walk the long grass first, and cut from the centre outwards.
• Build bonfires on the day. A heap left standing for a week will have a hedgehog asleep in the middle of it. Move the pile, then burn it.
• Deal with netting and drains. Peg down fruit netting, keep it 30cm off the ground, and cover any open drain, soakaway or steep-sided sunken gully.
• Leave hedgehog-sized gaps around raised beds, decking edges and log stores so nothing becomes a trap.

None of this requires a wild, unmanaged garden. It requires an untidy corner, an open gap, a dish of water and a ramp. Do that, and the rustling in the hedge at dusk will tell you it has worked.
