Fly honeysuckle: how to prune it?

Needs little pruning: in winter, thin out a few old branches at the base.
Rejuvenate an old, bare shrub by coppicing it in winter; it will regrow.

How much to cut, and how often?

One pruning period a year: November–March.
Grows best when left alone. Only remove dead, diseased or awkward branches.

What does it mean for wildlife?

Pruning in March can fall in the nesting season (15 March–15 August). Check carefully for nesting birds first: disturbing an active nest is against the law.
As a native plant, it feeds more insects than a non-native species.
Prunings can go on a dead hedge or brash pile in a corner of the garden: shelter for hedgehogs, wrens and insects.

Common mistakes

Clipping without first checking for nesting birds.
Pruning too much: it grows best when left alone.
Leaving a stub or sawing flush with the trunk: cut just outside the branch collar.

Caution: It flowers on last year’s wood: a shrub that is cut back hard flowers less the following year. Fly honeysuckle is poisonous: wear gloves and keep clippings away from children, pets and livestock.
