What kind of soil do they prefer?

They thrive in well-drained, acidic soil rich in organic matter.

How much sun do they need?

Camellias prefer partial shade, especially protection from hot afternoon sun.

Are they suitable for containers?

Yes, they do well in pots, especially dwarf varieties.

Do they need pruning?

Pruning is mainly done after flowering to shape the plant and remove dead or damaged branches.

Plant guide

Signs it needs repotting

Roots growing out of drainage holes.
Water drains very slowly or not at all.
Plant dries out much faster than usual.
Visible white, healthy roots circling the inside of the pot.

Safety

People: Ingestion of plant parts may cause mild stomach upset.
Pets: Mildly toxic to pets if ingested, causing vomiting or diarrhea.
Children: No specific safety concerns for children, but ingestion of any non-food plant material should be avoided.
Contact allergens: No significant contact allergens are known.
Airborne allergens: Pollen may cause seasonal respiratory allergies in sensitive individuals.
Edibility: This plant is not intended for consumption.

How to identify it

Glossy, dark green, leathery leaves
Large, showy flowers
Rose-like or peony-like blooms
Evergreen shrub or small tree
Smooth, gray-brown bark

Height: 3.65 to 4.57m
Spread: 2.44 to 3.05m
Leaves: dark green, glossy, evergreen
Flowers: white, pink, red, variegated, 5 to 13cm

Common problems

Scale insects — Small, immobile insects that attach to stems and leaves, sucking sap and weakening the plant.
Aphids — Tiny, pear-shaped insects that cluster on new growth, feeding on plant juices.
Sooty mold — A black, powdery fungus that grows on honeydew excreted by sap-sucking insects.
Bud drop — Flower buds fall off before opening due to stress from inconsistent watering, temperature fluctuations, or poor light.

Growing it

Propagation: cuttings, grafting
When to plant: spring, fall
Overwintering: In colder climates, container-grown camellias should be moved to a protected, unheated location like a garage or shed. Mulch heavily around the base of in-ground plants to protect the roots from extreme cold.
In containers: Camellias grow very well in containers, especially dwarf varieties, provided the pot is at least 15 gallons and has excellent drainage.

Cuttings

Take semi-hardwood cuttings in mid-summer to early fall.
Remove lower leaves and dip the cut end in rooting hormone.
Insert cuttings into a moist, well-draining potting mix.
Keep the cuttings consistently moist and in a humid environment, like a propagator or under a plastic bag.
Roots typically form within a few months.

Grafting

Graft desirable cultivars onto hardy rootstock, usually in late winter.
Use a whip-and-tongue or cleft graft.
Ensure the cambium layers align.
Secure the graft tightly with tape or twine.
Keep the graft union moist and protected until healed.

Plant camellias with other acid-loving, shade-tolerant plants like azaleas and hostas for a cohesive and healthy garden display.

Grows well with

Azalea — Azaleas share similar acidic soil and partial shade requirements, creating a beautiful woodland garden combination.
Rhododendron — These plants complement camellias with their lush foliage and vibrant blooms, preferring the same growing conditions.
Japanese Maple — Its delicate foliage and graceful form provide a lovely contrast to the camellia's structure and blooms.
Hosta — Hostas offer beautiful foliage texture and thrive in the shady, moist conditions that camellias prefer.

Keep away from

Boxwood — Boxwoods prefer alkaline to neutral soils, which can inhibit the growth of acid-loving camellias.
Lavender — Lavender needs full sun and very well-drained, alkaline soil, conditions that are detrimental to camellias.

Similar species

Camellia sasanqua — Sasanqua camellias bloom earlier in the fall and have a more open, spreading habit, while japonicas bloom later and are typically more upright.
Tea Plant — This species is primarily grown for its leaves used to make tea, and its flowers are generally less showy than Camellia japonica.
