Hedgehogs typically hibernate through the coldest months, often in piles of leaves, log stacks, or purpose-built shelters tucked into a quiet corner. Anything resembling a bonfire pile should always be checked carefully before lighting, since it can look like an ideal hibernation spot to a hedgehog settling in for winter.
Garden birds face different pressures depending on the time of year, and supplementary feeding is most valuable during two periods in particular: the late winter to early spring hungry gap, when natural food is scarce, and the breeding season, when adults are feeding hungry chicks.
Fresh water for drinking and bathing rounds out a decent set-up. Gardeners building out their feeding station for the first time typically start with a good spread of bird feeders to cover the different food types birds look for.
Design details matter more than they might appear to. Good insect houses combine hollow stems, such as bamboo or reed, with drilled wood blocks offering a range of hole diameters, roughly 2 to 10mm, since different species use different sized cavities. Natural, untreated materials are preferable to anything varnished or chemically treated.
Hedgehogs are one of the most recognisable mammals to visit British gardens after dark, often covering a surprising distance, sometimes a mile or more, over a single night as they forage. A garden that offers a route in, something to eat and somewhere quiet to rest is far more likely to see repeat visits than one that is sealed off and tidied within an inch of its life.
Application is simple but does depend on getting the conditions right. Nematodes are typically mixed with water and applied with a watering can or hose-end feeder directly onto moist soil, since they need moisture to move through it and reach their target. Soil temperature also matters:
