What else to prune in those months? June
Santa Barbara ceanothus (Ceanothus impressus): how to prune it?
- Shorten the flowered shoots, but always stay within the green, leafy growth.
- Never cut into old, bare wood: it will not reshoot from it.
- Dead or frosted branches can be removed at any time, back to healthy wood.
- For a wall-trained shrub: after flowering, cut back outward-growing branches and tie in new shoots.
How much to cut, and how often?
- One pruning period a year: June.
- Prune in moderation: never remove more than about a third of the shrub at once.
What does it mean for wildlife?
- Pruning in 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.
- Santa Barbara ceanothus (Ceanothus impressus) flowers in April–May, 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: Never prune hard and never in autumn: hard or late pruning can kill the plant.
