Helping Garden Wildlife Through Winter

Connectivity between gardens is often the missing piece. A small gap at the base of a fence, native hedging used in place of a solid boundary where practical, and less hard paving all help animals move between plots rather than being boxed into one. These small changes add up meaningfully over the course of a season.

Shelter is often overlooked. Many UK bee species are solitary rather than hive-dwelling, and a patch of bare, undisturbed soil in a sunny spot can serve as nesting ground for mining bees, while hollow stems and drilled wood blocks suit species that nest above ground. Choosing biological pest control over chemical sprays around flowering borders also helps protect the insects visiting them.

Fish are worth thinking through carefully. Ornamental fish will happily eat frogspawn and tadpoles, so a pond intended mainly for amphibians is usually better left fish-free. Leaving some leaf litter to settle at the bottom over autumn also gives amphibians a place to shelter through the colder months.

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.

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.

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.
