Indian horse chestnut: when to prune it?
As little as possible. If needed between January and February, in the dormant season, in dry, frost-free weather.
Indian horse chestnut: how to prune it?
- Remove dead, damaged and crossing branches.
- Give a young tree a sound framework: keep one leading stem and remove competing tops.
- Saw large branches off in three steps, just outside the branch collar, so that the wound can heal.
- Leave felling or crown reduction of large trees to a tree surgeon.
How much to cut, and how often?
- One pruning period a year: January–February.
- Never remove more than about a quarter of the crown at once. Better a little every year.
What does it mean for wildlife?
- The pruning months fall outside the nesting season (15 March–15 August), so you won’t disturb nesting birds.
- Indian horse chestnut 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
- Leaving a stub or sawing flush with the trunk: cut just outside the branch collar.
Caution: Do not prune in wet weather and avoid unnecessary wounds: horse chestnuts are susceptible to bleeding canker. Indian horse chestnut is poisonous: wear gloves and keep clippings away from children, pets and livestock.
