Southern bush honeysuckle: when to prune it?

In March, before new growth starts. It flowers on this year’s wood, so spring pruning costs no flowers.

What else to prune in those months? March

Southern bush honeysuckle: how to prune it?

  1. Every year, cut some of the oldest stems down to the ground to encourage young, free-flowering shoots.
  2. If the shrub becomes thin or untidy, cut all stems back to 15–20 cm above the ground in March; it reshoots quickly and densely.
  3. Remove dead wood and suckers that come up where you do not want them.

How much to cut, and how often?

  • One pruning period a year: March.
  • Prune in moderation: never remove more than about a third of the shrub at once.

What does it mean for wildlife?

  • Pruning in March can fall in the nesting season (15 March–15 August). Check carefully for nesting birds first: disturbing an active nest is against the law.
  • Southern bush honeysuckle flowers in June–August, 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 in summer: you would cut off the flowering shoot tips.
