Coppicing Hazel in a Small Wildlife Garden

Why hazel earns its place in a wildlife garden

Hazel (Corylus avellana) is one of the best small trees for a British wildlife garden. It is native, hardy and responds brilliantly to coppicing — the traditional practice of cutting stems to the ground to stimulate fresh, dense growth. In a small garden, a few coppiced hazel stools can provide more habitat than a much larger unmanaged tree. The catkins open in late winter, offering early pollen for bees. The nuts ripen in autumn and feed squirrels, mice, voles and birds such as jays and nuthatches. The dense multi-stemmed regrowth makes ideal nesting cover for blackbirds, robins and wrens. And for dormice — those elusive, protected mammals — a coppiced hazel stool is prime real estate.

Planning a coppice rotation for a small space

You do not need a wood to coppice hazel. Three to five stools, spaced about 1.5–2 metres apart, will fit a modest border. Plant bare-root whips between November and March. If you already have a mature hazel, you can start coppicing it this winter. The key is rotation: divide your stools into groups and cut one group each year. A four-year rotation suits a small garden. That means each stool is cut every fourth winter, giving stems three growing seasons to reach a useful size. For bean poles, a three-year rotation produces straighter, lighter stems. For dormice and nut production, a five- to seven-year rotation is better — but in a small garden, four years is a practical compromise. Always leave at least one stool uncut each year so there are always nuts and catkins available.

The cut: timing, tools and technique

Coppice hazel in winter, from late November to early March, while the tree is dormant. Avoid cutting during a hard frost — brittle wood shatters. Use sharp bypass loppers for stems up to 3 cm, and a pruning saw for thicker ones. Never use a strimmer or blunt axe, which tears bark and invites disease. Cut each stem 5–7 cm above the stool, angling the cut slightly away from the bud so water runs off. Do not cut into the swollen base of the stool itself. Work methodically around the stool, removing all stems of the current rotation. If you want to leave a few stems for nuts, choose two or three of the strongest and mark them with a tie. Cut the rest. After cutting, the stool will send up vigorous new shoots within weeks. Protect fresh growth from rabbits and deer with a temporary guard if necessary.

Using the harvest: bean poles, pea sticks and more

Hazel coppice is not just for wildlife — it pays you back. Straight stems make superb bean poles, lasting five to seven years if stored dry. Sort your cut stems into bundles: long, straight poles for runner beans and climbing French beans; medium stems for plant supports and obelisks; and the brushy tops for pea sticks. Pea sticks are invaluable for supporting peas, sweet peas and floppy perennials. Smaller side shoots can be woven into low hurdles or used as kindling. Bundle poles with twine and stand them upright in a dry shed or garage. Do not leave them on the ground, where they will rot. Any material too small to use can be piled nearby as a habitat stack for beetles, frogs and hedgehogs.

Making your garden dormouse-friendly

Dormice are rare and patchily distributed in Britain, mainly in southern counties. If you are lucky enough to live in a dormouse area, a coppiced hazel stool can become a vital link in their habitat. Dormice need connected cover — they rarely cross open ground. So plant hazel alongside a native hedgerow, or link your coppice to neighbouring trees with a corridor of honeysuckle, bramble and ivy. They feed on hazel nuts, blackberries, aphids and flowers, and they build nests in dense scrub. Leave some hazel stems uncut for several years to provide older, thicker growth. Avoid all pesticides. Keep a shallow water source, such as a saucer of water at ground level. Do not disturb leaf litter or deadwood piles between November and April, when dormice may be hibernating. You are unlikely to see a dormouse, but you may find a characteristic gnawed nut — a neat round hole with tooth marks around the rim — which is a thrilling sign.

Other wildlife that benefits

Even without dormice, coppiced hazel is a wildlife magnet. The dense regrowth shelters nesting birds. The catkins feed early bees and hoverflies. The leaves are food for the larvae of several moths, including the nut-tree tussock and the December moth. The nuts are taken by wood mice, bank voles, grey squirrels and great spotted woodpeckers. And the cut stools themselves, if left to develop a little deadwood, become home to fungi, beetles and solitary bees. In a small garden, the golden rule is to coppice in patches, not all at once. That way, there is always somewhere for wildlife to shelter, feed and breed. A four-year rotation on three or four hazel stools gives you a sustainable supply of bean poles, a changing mosaic of habitat, and a garden that is alive with British wildlife.
