Koromiko (Veronica salicifolia): how to prune it?

1. Cut dead and frost-damaged branches back to healthy wood, which is often only clearly visible in May.
2. Trim the shrub lightly, about a third of the young shoots, just above a few leaves.
3. Remove spent flower spikes in autumn or spring.
4. An older plant can be renewed over a few years by shortening a few branches a little harder each time, within green wood.

How much to cut, and how often?

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

What does it mean for wildlife?

• Pruning in April can fall in the nesting season (15 March–15 August). Check carefully for nesting birds first: disturbing an active nest is against the law.
• Koromiko (Veronica salicifolia) flowers in July–September, when it attracts bees and butterflies.
• 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.
