Helping Garden Wildlife Through Winter

slug nematodes are microscopic roundworms that occur naturally in soil, and certain species have been developed for use against specific garden pests. Rather than acting as a broad chemical treatment, each nematode species is matched to a particular pest, seeking it out and interrupting its lifecycle with far less impact on the rest of the garden than a chemical spray.

Placement decides whether the house gets used at all. A fixed position at around waist to head height, facing south or south-east to catch the morning sun, and sheltered from driving rain and strong wind, gives insects the stable conditions they need. Once occupied, the house is best left undisturbed through the nesting and overwintering period.

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.

A garden pond, even a small one, is one of the most valuable additions for wildlife. Frogs and newts use it to breed, dragonflies and damselflies lay eggs in it, and birds and hedgehogs will drink and bathe at the edges given the chance.

Winter is one of the harder seasons for garden wildlife. Natural food becomes scarce, cold weakens smaller animals quickly, and many species rely on undisturbed shelter to see them through to spring rather than active foraging.

Easy access matters most. A shallow, gently sloping edge lets amphibians move in and out of the water without difficulty, while steep, hard-edged ponds can be surprisingly difficult for them to use. Nearby damp, shady spots, a log pile or a compost heap close to the pond, give them somewhere to shelter and hibernate once they leave the water for the colder months.
