Mongolian lime: when to prune it?
Prune during dormancy, from December to February, on a dry, frost-free day. A young tree is shaped in its first years; after that it needs hardly any pruning.

Mongolian lime: how to prune it?
- Train a straight trunk with a single leader and remove competing leaders.
- Take out dead, crossing and damaged branches; cut just outside the branch collar.
- For a taller clear trunk along an avenue or above a terrace, remove the lowest branches gradually over several years.
- To keep the crown even, light trimming is enough.
How much to cut, and how often?
- One pruning period a year: December–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.
- Mongolian lime 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
- Leaving a stub or sawing flush with the trunk: cut just outside the branch collar.
Caution: Never prune during flowering in July, when the bees are in the tree. Leave major work to an arborist.
