Whitebeam: when to prune it?

Dead, diseased and broken branches can be removed at any time of year. Formative pruning in winter or after flowering.

Little needed: remove crossing branches and water shoots.
Train a young tree with a single leader and a clear stem tall enough for the spot, e.g. 2 m above a path.
Cut out branches with fireblight at least 30 cm below the visibly affected part, in dry weather.

There are 2 pruning periods a year: July–August and December–February. You don’t have to prune in every one.
Grows best when left alone. Only remove dead, diseased or awkward branches.

Pruning in July–August can fall in the nesting season (15 March–15 August). Check carefully for nesting birds first: disturbing an active nest is against the law.
Whitebeam flowers in May, when it attracts bees.
In September–October birds eat the fruit: leave some on the plant or on the ground.
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.

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: Can carry fireblight.
