Camellia 'Donation' (Donation camellia) care

Light

Bright but filtered. Camellia 'Donation' burns within days in unfiltered south-facing summer sun, and stops growing within months in deep shade. Dappled or part shade suits it best; it tolerates more light and cooler positions than japonica camellias. Avoid early-morning sun on frosted buds, which spoils the blooms, and very deep shade, which reduces the abundant flowering. If you only have a south window, set the plant back 1.5 m or hang a sheer curtain — both knock the intensity down into the right range.

Watering

Watering camellia 'donation': when the top 3-5 cm of soil is dry; keep evenly moist in late summer. The number that matters isn't the day of the week — it's how dry the top 2-3 cm of the pot feels. A finger in the soil tells you more than a watering app. After every watering, tip the saucer. Keep the soil consistently moist, ideally with rainwater, as camellias resent lime. The flower buds set in late summer, so drought from July to September causes bud drop the next spring. Mulch to hold moisture and protect surface roots.

Soil and pot

Camellia 'Donation' grows best in moist, humus-rich, free-draining acidic (ericaceous) soil. Needs acidic soil around pH 5.5-6.5; alkaline or limey ground causes iron-deficiency chlorosis. Use ericaceous compost in pots and enrich beds with leaf mould and composted bark. Sharp drainage is essential despite the demand for steady moisture. A pot with a working drainage hole is non-negotiable for this species — even free-draining mix will turn soggy in a closed planter. If you love the look of a decorative pot without a hole, use it as a cachepot around an inner nursery pot you can lift out to water.

Humidity and temperature

Camellia 'Donation' sits happiest at around 40-70% humidity and -12 to 30°C (10 to 86°F). An outdoor evergreen comfortable in ambient temperate humidity. A sheltered position with reasonable soil and air moisture supports good flowering and prevents the leaf scorch and bud drop seen in dry, exposed sites. If you keep the room above year-round and avoid placing the plant near a cold draught, a hot radiator, or an air-conditioning vent, you have already handled the two biggest indoor stressors.

Fertilising

Feed camellia 'donation' sparingly. Feed with an ericaceous fertiliser after flowering in spring to fuel new growth and next year's buds, with an optional light early-summer feed. Stop feeding by late summer to let growth harden, and avoid any lime-based products that raise soil pH. Skip fertiliser entirely on a stressed, recently-repotted, or actively wilting plant — fertiliser salts make damage worse, not better. Wait for a round of healthy new growth before resuming a feeding rhythm.

Common problems

Below are the issues we see most often on camellia 'donation' in the Growli community. Each is annotated with the most common cause so you know where to start.

• Bud drop — Buds may fall before opening if the roots dry out in late summer or temperatures swing sharply. Water consistently from midsummer onward and mulch to keep the root zone moist.
• Leaf yellowing (chlorosis) — Yellow leaves with green veins indicate alkaline soil or hard water blocking iron uptake. Grow in ericaceous soil, water with rainwater, and apply sequestered iron if symptoms appear.
• Frost-spoiled flowers — Open blooms and buds brown after hard frost, worsened by morning sun. Site away from cold, exposed, east-facing positions so frosted flowers thaw slowly.
• Scale insects and sooty mould — Sap-sucking scale on stems and leaf undersides produces honeydew and black sooty mould. Wipe off small infestations and improve airflow around the plant.

Propagation

Propagate from semi-ripe cuttings in late summer in ericaceous, free-draining compost with gentle bottom heat; leaf-bud cuttings and layering also succeed. The hybrid comes true only from cuttings, not seed. Propagation is the cheapest, most satisfying way to expand a collection — and it doubles as insurance against losing a mature plant to an accident. Take a backup cutting once the parent is established and healthy.

Toxicity to pets

Camellia 'Donation' is pet-safe. 'Donation' is a Camellia (family Theaceae); the ASPCA lists camellia, including Common Camellia (Camellia japonica, a parent of this williamsii hybrid), as non-toxic to dogs, cats, and horses. The plant itself is safe, though eating a lot of any foliage can cause mild gastrointestinal upset. If you keep cats, dogs, or curious children in the house, weigh placement carefully — a high shelf or a hanging planter is enough for casual safety. For severe ingestion incidents, call your local vet and the ASPCA Animal Poison Control Center (in the US, 888-426-4435).

Pet-safety status is sourced from the ASPCA Toxic and Non-Toxic Plant List, which catalogues the most-asked-about plants for cats, dogs, and horses.
