Scots pine: when to prune it?

Dead, diseased and broken branches can be removed at any time of year. To keep a garden pine compact, pinch the new shoots (‘candles’) back by half in May–June.

Scots pine: how to prune it?

  1. Pinch or cut the candles in May–June, once they have extended but before the needles have spread out: the pine then branches more densely.
  2. Never cut a pine back into bare branches: no new buds will form there.
  3. On a forest tree the lower branches die off on their own; saw them off cleanly, just outside the branch collar.

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.
  • Host plant: caterpillars of butterflies or moths eat the leaves.
  • As a native plant, it feeds more insects than a non-native species.
  • 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: Never remove a large part of the green crown at once: a pine cannot recover from hard pruning.
