False spiraea: when to prune it?
In March, before it leafs out. One pruning a year is enough.
What else to prune in those months? March
False spiraea: how to prune it?
- Every year, remove a third of the oldest stems right at the base.
- Or cut the whole shrub back every 3–4 years to 30–50 cm above the ground; it regrows vigorously.
- Remove dead, damaged and weak stems.
- Dig out or cut off suckers where the shrub must not spread.
How much to cut, and how often?
- One pruning period a year: March.
- Prune in moderation: never remove more than about a third of the shrub at once.
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.
- False spiraea flowers in July–August, when it attracts bees.
- 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.
- Leaving a stub or sawing flush with the trunk: cut just outside the branch collar.
Caution: It flowers on new wood, so a hard pruning in March costs no flowers. Do not prune in summer: you would cut off the flowering shoots.
