Staghorn sumac: when to prune it?
It does not need pruning. If you want to, do it in February–March while it is still dormant.
Staghorn sumac: how to prune it?
- Remove dead, crossing or broken branches back to the trunk or a healthy side branch.
- For extra-large leaves you can cut it back to 30–60 cm above the ground every 1–2 years in February–March; it will then flower and fruit less.
- Cut suckers off as low as possible, often rather than too late.
How much to cut, and how often?
- One pruning period a year: February–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.
- Staghorn sumac flowers in June–July, 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: Pruning and root damage stimulate even more suckers. Wear gloves and long sleeves: the milky sap can irritate the skin.
