Hazel (Corylus avellana) growing in a UK garden

Hazel is a native British multi-stemmed tree or large shrub found in hedgerows and woodlands throughout the UK. Its golden catkins are one of the earliest signs of spring, appearing in February. Hazelnuts ripen in autumn and are prized by squirrels, dormice, and jays. Traditionally coppiced for centuries, hazel provides excellent stakes, bean poles, and garden supports.

How to grow hazel

Plant bare-root hazel between November and March in a sunny or lightly shaded position. It tolerates most soils, including chalk and heavy clay, and grows well in exposed sites. For nut production, plant two or more different cultivars to ensure cross-pollination. Space trees 4-5 metres apart, or 30-40 cm apart for a hedge. Water during dry spells in the first year. Hazel makes an excellent understory tree in woodland gardens and is one of the best native species for wildlife. The contorted form 'Contorta' is prized for its twisted stems in winter flower arrangements.

Pruning

Coppice every 7-10 years in winter by cutting all stems to 15-20 cm above ground. This traditional management creates a multi-stemmed habit and produces straight poles for garden use. Alternatively, prune as a single-stemmed tree by removing lower branches and thinning the crown. For hedges, trim in late winter before catkins shed their pollen.
