Wildlife Gardening Tips

Provide both nectar plants for adults and host plants for caterpillars. Butterflies need flat-topped or clustered flowers for landing — buddleia, verbena bonariensis, sedum, and echinacea are reliable nectar sources. Crucially, include larval host plants: nettles for painted ladies and red admirals, milkweed for monarchs, fennel and dill for swallowtails. A garden with only nectar plants is a refueling stop, not a habitat.

Berry-producing shrubs — elderberry, holly, viburnum, hawthorn, and serviceberry — feed the widest range of birds from late summer through winter. Seed-bearing flowers left standing through fall and winter — coneflowers, sunflowers, and ornamental grasses — attract finches and sparrows. Dense native hedges provide nesting sites. A single mature native oak supports over 500 insect species that in turn feed insectivorous birds.

A wildlife pond needs shallow, gently sloping edges so frogs, newts, and hedgehogs can enter and exit safely. Include submerged oxygenating plants, floating plants for cover, and marginal plants at the edges. Avoid fish — they eat frog spawn, dragonfly larvae, and other invertebrates that make a pond ecologically rich. Even a half-barrel sunk into the ground attracts dragonflies and frogs within the first season.

Cut a 13cm-square gap at the base of garden fences so hedgehogs can move between gardens. Leave a corner of the garden slightly wild with a log pile and leaf litter for nesting. Avoid slug pellets containing metaldehyde — they poison hedgehogs. Provide a shallow dish of fresh water and, in autumn, supplementary cat biscuits (not bread or milk). Check bonfires and compost heaps before disturbing them, especially from November through March.

A single bat can eat 3,000 mosquitoes and midges in one night — they are the most effective natural pest control for flying insects. Mount bat boxes 3-5 meters high on south or southwest-facing walls or tree trunks, sheltered from prevailing wind. Place boxes near linear features like hedges and tree lines that bats use as flight corridors. Install at least two boxes facing different directions to give bats options in varying weather.

Wildlife corridors connect habitat patches so species can move safely between feeding, breeding, and sheltering areas. In a garden, this means hedges rather than fences, gaps at fence bases for ground animals, climbing plants on walls for insects, and continuous planting along boundaries rather than isolated beds. Coordinate with neighbors to create connected habitat across multiple gardens — even a 13cm gap in every fence on a street creates a wildlife highway through the entire block.
