Siberian fir: when to prune it?
Rarely needed. Do small corrections in February–March, before bud break.
Siberian fir: how to prune it?
- Cut out dead, broken and frost-killed twigs back to healthy wood.
- Keep a single leader: cut out a second, competing top.
- Leave the lower branches as long as possible; only remove them once they are completely bare and dead.
How much to cut, and how often?
- One pruning period a year: February–March.
- Never remove more than about a quarter of the crown at once. Better a little every year.
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.
- 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: Firs do not regrow from bare wood: never cut into the top or prune the tree into shape.
