For gardens without much bare soil to spare, a ready-made shelter is a simple addition. Many gardeners start with bee hotels positioned in a sheltered, sunny spot close to nectar-rich planting.
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.
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.
Building a planting scheme with wildlife in mind alongside the usual food and shelter provisions rounds out the picture. A well-stocked feeding station, including a reliable source of bumblebee food, complements planting choices particularly well during gaps in flowering.
Birds need consistent feeding through frosty spells, when natural food sources are hardest to find and energy demands are highest. Keeping feeders topped up, and providing water that is not frozen over, matters more in a hard frost than at almost any other point in the year; a small area gently melted with warm water is a better approach than breaking ice by force.
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: most products need the soil to be above a minimum threshold, often around 5°C, to remain effective.
