Pin oak: how to prune it?
- Little needed: the crown naturally grows into a regular pyramid. On a young tree, keep a single leader.
- The lower branches droop: on an avenue tree, remove them gradually to create clearance underneath.
- Cut just outside the branch collar and leave no stubs.
How much to cut, and how often?
- There are 2 pruning periods a year: July–August and November–February. You don’t have to prune in every one.
- Grows best when left alone. Only remove dead, diseased or awkward branches.
What does it mean for wildlife?
- Pruning in July–August 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.
- Pruning too much: it grows best when left alone.
- Leaving a stub or sawing flush with the trunk: cut just outside the branch collar.
Caution: Needs acid soil: on chalk its leaves turn yellow (chlorosis).
