Korean fir: when to prune it?
Pruning is almost never needed: it naturally grows into a fine cone shape. At most, remove a double leader or a damaged branch in March.
What else to prune in those months? March
Korean fir: how to prune it?
- With two competing leaders, cut out the weaker one so that a single leader remains.
- Remove dead or broken branches back to the trunk or a healthy side branch.
- A side branch that is too long can be shortened to just above a side shoot with needles.
- Never cut into bare wood without needles: a fir will not regrow from it.
How much to cut, and how often?
- One pruning period a year: 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: Do not top the tree to keep it smaller: it would lose its cone shape for years.
