Weymouth pine: when to prune it?
Dead, diseased and broken branches can be removed at any time of year. If pruning is needed, do it in May–June.
Weymouth pine: how to prune it?
- Prune as little as possible: a Weymouth pine looks best in its natural, open shape.
- Remove branches with blister rust (orange blisters on the bark) well below the infected part.
- If the trunk is infected, everything above it dies; felling is then often the best option.
How much to cut, and how often?
- One pruning period a year: May–June.
- Grows best when left alone. Only remove dead, diseased or awkward branches.
- Most conifers do not regrow from old, bare wood. So never cut back into the brown part (exception: yew).
What does it mean for wildlife?
- Pruning in May–June 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.
- Cutting back into bare brown wood: it will not regrow from there.
- 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: Susceptible to blister rust, a fungus that also lives on blackcurrant and gooseberry.
