Cyprus Cedar (Cedar of Cyprus) care

Light

Aim for at least 4-6 hours of direct sun on the leaves. Requires full sun for best growth and form. Tolerates very light partial shade but develops a looser, less attractive crown. Plant in an open, unshaded position away from tall buildings and competing tree canopies. If your only bright window faces south, that's perfect for cyprus cedar — same window any aroid would fry on.

Watering

Watering cyprus cedar: every 10-14 days when young; established trees rely mostly on rainfall. 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. Prefers moist to dryish, well-drained conditions. Water young trees regularly during their first two to three growing seasons to establish deep roots. Once established, this species is notably drought-tolerant and resents waterlogged soil. Reduce watering significantly in autumn and winter.

Soil and pot

Cyprus Cedar grows best in well-drained loam, sandy loam, or chalky soil; neutral to mildly alkaline ph 6.5–7.5. Adaptable to a range of soil types provided drainage is excellent. Performs well on limestone-derived soils, reflecting its native Cypriot habitat. Avoid heavy clay or permanently wet ground, which encourages root rot and Phytophthora. 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

Cyprus Cedar sits happiest at around 30–60% humidity and -20°C to 35°C (-4°F to 95°F). Tolerates the relatively low humidity of Mediterranean-type summers. Adapted to seasonally dry conditions and does not require supplemental misting. Good air circulation around the canopy is beneficial. 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 cyprus cedar sparingly. Apply a slow-release balanced granular fertiliser (e.g. 10-10-10) once in early spring. Young trees benefit from a dilute liquid feed once or twice during the growing season. Avoid high-nitrogen feeds in late summer, which can encourage soft growth susceptible to early frosts. 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 cyprus cedar in the Growli community. Each is annotated with the most common cause so you know where to start.

• Root rot (Phytophthora) — Heavy or poorly drained soil encourages Phytophthora root rot, causing yellowing needles, dieback and eventual death. Plant on a slope or raised bed and never water excessively.
• Needle cast fungi — Pestalotiopsis and Kabatina fungi can cause browning and premature shedding of needles, especially in wet or humid conditions. Improve airflow, remove affected material, and apply a copper-based fungicide if severe.
• Pine weevil (Hylobius abietis) — Adult weevils chew bark at the base of young stems, girdling and killing young plants. Protect newly planted trees with physical barriers and inspect the root collar regularly.

Propagation

Seed: collect ripe cones in autumn, extract seeds and sow fresh in free-draining seed compost under cool glass; germination can be erratic and slow (1–3 months). Semi-hardwood cuttings taken in late summer and treated with rooting hormone can root but success rates are moderate. Grafting onto Cedrus atlantica rootstock is used for named selections. 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

Cyprus Cedar is mildly toxic to pets. Cedrus species are not individually listed by ASPCA. True cedar foliage and pollen can cause mild gastrointestinal irritation if ingested by pets and may cause skin irritation or allergic reactions in sensitive individuals. Cedar essential oils can be harmful to cats. Treat with caution and keep away from pets that habitually browse foliage. 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.
