Witch hazel: when and how to prune

Hamamelis

Prune a witch hazel hardly at all, and only after flowering, in March–April: just remove dead, damaged or crossing branches, and take off wild shoots below the graft union straight away.

Witch hazel flowers in the depths of winter, with fragrant, crinkled flowers on bare branches, and turns fiery yellow to orange-red in autumn. It slowly grows into a broad, vase-shaped shrub of 3–5 m, and that shape comes naturally. It does not take kindly to hard pruning: it regrows slowly and then flowers less for years. So the most important pruning job is something else: most witch hazels are grafted, and wild shoots from the rootstock have to go.

Witch hazel: when to prune it?

Prune after flowering, in March–April, before the leaves open. You can still see the shape of the shrub clearly, and it has the whole summer to make new branches, with the flower buds for next winter.

Don’t prune in summer or autumn: the flower buds form in summer, and anything you cut off after that won’t flower.

Remove wild shoots below the graft union as soon as you see them: the younger they are, the easier it is.

Witch hazel: how to prune it?

Prune as little as possible: only remove dead, damaged or crossing branches, back to healthy wood or to a side branch.
Shorten an overlong branch to just above an outward-facing side branch. Never cut the shrub back hard: it grows slowly and does not readily reshoot from old wood.
Witch hazels are usually grafted onto an American rootstock. Shoots that come from the stem or from the ground below the graft union grow from that rootstock: cut them off flush with the stem.
If you are not sure whether a shoot is wild, look in autumn: the rootstock, Hamamelis virginiana, already flowers in October–November with small yellow flowers, often still among the leaves.
Use sharp, clean secateurs, and cut just above a bud or a side branch without leaving stubs: a stub dies back and lets in fungi.
If it is too big for its spot, reduce it over a few years, one or two branches at a time back to a side branch. It does not like being moved.

How much to cut, and how often?

Little: a mature witch hazel often needs nothing for years, apart from a dead or crossing branch.
Never remove more than a few branches a year: hard pruning leads to upright water shoots and a few years of poorer flowering.
Wild shoots, on the other hand, always and straight away: if you leave them, they will take over from the grafted shrub within a few years.

What does it mean for wildlife?

On mild winter days the first honeybees and queen bumblebees collect pollen and nectar from the flowers. So only prune once flowering is over.
If you prune after mid-March, you are in the nesting season (15 March–15 August): check the shrub for a nest first, as disturbing an active nest is against the law.
Leave the fallen autumn leaves under the shrub: they keep the soil cool and moist, just as it likes, and hedgehogs and insects spend the winter in them.
Witch hazel is not a native shrub. Plant native early flowerers with it, such as hazel, willows or blackthorn: that way bees find something to eat from January to April.

Common mistakes

Leaving wild shoots from the rootstock, until after a few years they take over from the grafted shrub.
Cutting the shrub back hard or clipping it all over, so it flowers less for years.
Pruning in summer or autumn, so the flower buds for winter are gone.
Leaving stubs instead of cutting back to a side branch or a bud.
Pruning after mid-March without checking for nests first.

Caution: If you leave wild shoots from the rootstock, within a few years they will take over from the grafted shrub.
