Japanese spindle: when to prune it?

In May–June and at the end of August.

Trim a hedge twice a year: in May–June and from late August into September.
On variegated forms, remove shoots with all-green leaves: they grow more strongly and crowd out the variegated parts.
It sprouts well from old wood: a hedge that has grown too big or bare can be cut back hard.

Trim a hedge once or twice a year, after the first flush of growth (late June) and, if needed, in late summer. Check first that no birds are nesting.

Pruning in May–June and 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.
A dense hedge gives birds a place to nest and shelter, and hedgehogs take cover underneath. Leave some leaves at the base.
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.
Letting the hedge grow wider at the top than at the bottom: the base then goes bare.

Caution: Wear gloves and clear up the prunings: all parts are poisonous, to pets and livestock too.
