Indian bean tree: when to prune it?
At the end of winter (February–March), just before its late leafing-out.
Prune while dormant, from November to March, but not in freezing weather.
Indian bean tree: how to prune it?
- Tolerates hard pruning: on the mophead form you can cut the branches back every few years to short stubs on the head.
- Prune a tree little: remove dead, crossing and low branches.
- Cut back twigs killed by winter frost to healthy wood.
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.
- Indian bean tree flowers in 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: Don’t let shoots grow below the head of a grafted mophead: they come from the rootstock and grow into an ordinary Indian bean tree.
