How to Grow Camellias
The short answer
Camellias grow best in partial shade in acidic, well-drained soil enriched with organic matter; Clemson Extension advises avoiding sites with hot afternoon sun, and keeping a 2- to 3-inch mulch layer over the roots because camellias are shallow-rooted and do not tolerate drought.
Prune, if at all, immediately after flowering. Camellias set next season's flower buds on growth made after bloom, so pruning in summer, fall, or winter cuts off the coming display. Most plants need only removal of dead wood and the occasional wayward shoot.
What camellias are and where they grow
Camellias are broadleaf evergreen shrubs prized for rose-like flowers in the cool months when little else blooms. The two garden mainstays are Camellia japonica, with larger leaves and flowers, and the smaller-leaved, sun-tolerant Camellia sasanqua; between species and cultivars the bloom season spans fall through spring.
They are plants of the humid Southeast and mild-winter West: reliably hardy in roughly zones 7-9, with select cold-hardy hybrids pushing colder. In marginal zones, site them out of winter wind and morning winter sun.
Planting camellias
- 1Choose bright shade — Partial shade is ideal; avoid hot afternoon sun and, in cold areas, early morning sun on frozen buds. Older, established camellias with shaded roots can handle more sun.
- 2Build acidic, organic soil — Camellias need well-drained, slightly acid soil rich in organic material. Work compost or fine pine bark into the planting area; do not plant in soggy ground.
- 3Plant slightly high — Set the root ball with its top at or slightly above grade so water drains away from the crown, backfill, and water thoroughly.
- 4Mulch 2-3 inches — Maintain a 2- to 3-inch mulch layer over the root zone to conserve moisture; camellias do not tolerate drought.
Water and fertilizer
Keep soil evenly moist, especially through the first two summers and during bud set in late summer; drought stress then translates into dropped flower buds. Camellias are light feeders: Clemson notes they can grow well with little fertilizer, and light applications of an acid-forming azalea/camellia fertilizer after bloom are plenty. Overfeeding scorches leaves and forces soft growth.
Pruning camellias
Camellias need very little pruning: remove dead or damaged branches and long shoots that spoil the shrub's form. The timing rule is absolute, though: prune immediately after flowering ends, before new growth matures, because later pruning removes next year's flower buds.
✔ Thinning a few interior branches after bloom improves air circulation, which also reduces flower blight and scale problems.
Common problems
Camellia flower blight (browning blooms that drop suddenly), tea scale on leaf undersides, and bud drop from drought or cold snaps are the classics. Sanitation helps most with flower blight: rake up and discard fallen petals and flowers rather than leaving them under the shrub.
