Water and Biodiversity in the Garden

Water-saving earthworks, native hedgerows, and habitat corners that keep rainfall in the root zone and bring useful wildlife into the garden.

Water retention

Holding rainfall where plants can reach it

Swales follow the contour and slow runoff so water soaks into the soil. Rainwater barrels capture roof runoff for dry spells, and a deep layer of mulch keeps the surface moist and cool.

Drip irrigation delivers water at the root zone with less loss to evaporation than overhead watering, so each litre does more work.

Native hedges

Mixed native hedgerows act as windbreaks, wildlife corridors, and perches for predatory birds.

Beneficial insect shelters

Bundles of hollow stems, log piles, and uncultivated corners give pollinators and predators a place to overwinter.

A nectar calendar

Plan flowering perennials so that pollen and nectar are available from early spring through late autumn.
