Japanese plum: when to prune it?
In summer, in July–August after harvest, in dry weather. Not in winter.
Japanese plum: how to prune it?
- Build an open crown with 3–4 main branches; cut young trees back lightly after planting.
- Remove dead, diseased, crossing and inward-growing branches.
- Take out water shoots (fast, upright shoots) and thin the crown so light and air get in.
- Cut with a sharp, clean knife or secateurs and make clean cuts.
How much to cut, and how often?
- One pruning period a year: July–August.
- Prune in moderation: never remove more than about a third of the shrub at once.
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.
- Japanese plum flowers in March–April, 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: Do not prune stone fruit in winter: silver leaf then enters through the pruning wounds, a fungus that can kill the tree.
