Camellia: when and how to prune
Camellia japonica
Prune a camellia after flowering, in April–May, and only lightly: cut overlong branches back to just above a leaf or a side branch, and remove dead and weak branches.
The camellia is an evergreen shrub with glossy leaves and large flowers in February–April, when the garden is still largely bare. It grows slowly and keeps a good shape on its own, so it needs little pruning. Timing does matter: from mid-June it forms next year’s flower buds. So prune straight after flowering, and then not again. That way you get a compact shrub that is covered in flowers every spring.

Camellia: when to prune it?
Prune after flowering, in April–May, when the last flowers have faded and the new shoots are starting to grow.
Don’t prune after mid-June: the camellia then forms the buds for next spring, and you would cut them off.
Prune a camellia in a pot at the same time, and repot it straight away if needed.
Camellia: how to prune it?
- Cut overlong branches back to just above a leaf or a side branch growing in the right direction. It will sprout again there, with new twigs.
- Remove dead, weak and inward-growing branches, to let light and air into the shrub.
- Reduce a shrub that is too big gradually over a few years, each time after flowering. A camellia also sprouts from old wood, but needs a little time to do so.
- Pick up fallen flowers and cut off brown, rotting ones: that way you don’t spread fungi that attack the flowers.
- Too many buds on one twig? Remove a few in summer: the remaining flowers will be larger.
How much to cut, and how often?
- Little: only what grows out of shape, and dead or weak branches.
- An old, oversized shrub: over two or three years, part of the longest branches each time, never everything at once.
What does it mean for wildlife?
- April–May falls in the nesting season (15 March–15 August). Blackbirds and dunnocks like to nest in a dense camellia: look carefully first, and spare an active nest.
- Single-flowered camellias with visible stamens are an early meal for bumblebee queens in February–April. Double flowers offer insects nothing.
- Scale insects under the leaves are eaten by ladybirds and parasitic wasps. So don’t spray, but let them do their work.
- A camellia is a non-native plant of little value to native insects. Combine it with native plants for acid soil that do provide food, such as rowan, bilberry or holly.
Common mistakes
- Pruning after mid-June or in autumn, so the flower buds are gone.
- Clipping a camellia all over like a hedge, so its natural shape is lost.
- Cutting back an oversized shrub hard in one go.
- Pruning without first checking for nests.
Caution: Don’t prune after mid-June, as it is then forming next year’s buds.
