Hazel has been coppiced in Britain for thousands of years. A well-managed stool — the woody base from which new shoots rise — can live for centuries, producing straight rods on a rotation of seven to fifteen years. When a stool is neglected, it becomes overstood: too many stems, too large, too shaded. Light fails to reach the woodland floor, the stems grow crooked and diseased, and the stool slowly weakens. Starting to coppice again is one of the most rewarding acts of woodland care. It rejuvenates the tree, lets in spring light for bluebells and wood anemones, and yields material for traditional green woodcraft.
Begin with a slow, careful look. Check the health of the stool and the stems. Look for honey fungus: white fan-shaped mycelium under the bark, black bootlace strands in the soil, or clusters of honey-coloured mushrooms in autumn. Coral spot appears as small pink pustules on dead wood. Dieback shows as dead tips and thinning crowns. Tap the stool with a mallet — a hollow sound may mean rot at the centre. If the stool is hollow but still vigorous, it can often be coppiced carefully; if it is crumbling and weak, consider a phased cut instead.
Check access and safety. You need a clear escape route, firm footing, and room to swing a saw or billhook. Look for wildlife: birds’ nests, dormouse nests, or bat roosts. Coppicing in winter avoids the main nesting season, but protected species can still be present. If in doubt, leave that stool and seek advice. Finally, assess light. A stool in deep shade may need neighbouring trees thinned first, or a partial cut over two winters.
The best time to coppice hazel is the dormant season, from late November to late February, ideally before the buds burst. Avoid hard frost, when wood is brittle, and avoid very wet spells when soils are easily poached. You will need a sharp pruning saw, loppers, secateurs, and perhaps a billhook for smaller stems. Wear gloves, eye protection, and sturdy boots. Keep tools clean and sharp — a clean cut heals faster and reduces disease. Work with a partner if possible, especially when removing larger stems.
Start by removing dead, diseased, and damaged stems. Cut them cleanly near ground level, leaving a short stump of 2–5 cm. Then work through the remaining stems. For a healthy, vigorous stool, cut all stems to ground level in one go. For an old, weak stool, cut only half the stems this winter and the rest next winter, so the stool is not exhausted. Use a saw for stems thicker than your thumb. If the bark tends to tear, undercut slightly first, then cut from above. Angle the cut gently downwards so rain runs off, but do not cut into the stool itself — the dormant buds at the base are the future of the tree. Never cut high and leave a long stump; it will die back and rot. Remove all cut material from the stool. Use it for crafts, or build a habitat pile nearby.
New shoots should appear in spring from the dormant buds around the edge of the stool. Protect them from deer, rabbits, and livestock with temporary fencing or individual guards. Keep grass, brambles, and bracken cut back for the first two or three summers, so the shoots are not smothered. After two or three years, thin the shoots to leave six to twelve of the strongest per stool. Cut the surplus at ground level. This early thinning directs energy into the best rods. Then leave the stool to grow on. A seven-year rotation gives pea sticks and small rods; ten to fifteen years gives hurdles, beanpoles, and craft wood. Mark the stool and record the date, so you know when the next cut is due.
Freshly cut hazel is green wood — easy to cleave, shave, and bend. Traditional green woodcraft uses it for hazel hurdles, wattle fencing, beanpoles, pea sticks, walking sticks, shepherds’ crooks, tool handles, tent pegs, and thatching spars. Work it while still wet, using a shave horse and drawknife. Split rods for hurdles by cleaving with a froe, then weave them between uprights. For longer life, season rods in a dry, airy shed, stacked off the ground with spacers between layers. Bark can be left on or stripped, depending on the product. Every cut stem is a resource, not waste.
Aftercare is simple: keep the stool clear, protect the shoots, and plan the next rotation. A neglected hazel stool, cut with care, will reward you with straight rods, a healthier woodland, and a living link to Britain’s traditional woodland economy. Start small, learn from each cut, and enjoy the quiet satisfaction of bringing an old stool back into cycle.
