Andean Cedar Plant Care

Andean Cedar (Cedrela angustifolia) belongs to the Meliaceae family within the Cedrela genus. Andean Cedar is native to South America. Andean Cedar is also known as Argentine Cedar.

Andean Cedar displays a tall, upright tree growth habit, reaching up to 50 ft tall with a spread of approximately 20 ft. Andean Cedar produces small, fragrant white flowers in clusters.

Leaf size: approximately 6 inches.

Water a young or newly planted Andean Cedar every 7–14 days, soaking the whole root zone, until it is established — usually one to two growing seasons. Established trees mainly need water during long dry spells. In a container, water whenever the top few centimetres of soil are dry.

Andean Cedar thrives in full sun to partial shade.

Cedrela angustifolia tolerates temperatures of 60–85°F. Andean Cedar prefers humidity levels of 50–80%. A pebble tray or humidifier helps maintain adequate moisture around the plant.

Well-draining loamy soil with added compost for nutrients. Good drainage is essential for Andean Cedar to prevent waterlogging, which leads to root rot and fungal issues.

Feed Andean Cedar every 6 months during the growing season with a balanced, slow-release fertilizer at the rate on the label. Established trees in good soil often need little extra feeding, so let weak growth or pale foliage guide you.

Stop feeding by late summer so new growth can harden before winter.

Choose a spot with full sun to partial shade and well-draining loamy soil with added compost for nutrients. Avoid low spots where water collects after rain.

Andean Cedar is suited to USDA Zone 13a.

Plant container-grown or balled-and-burlapped trees in spring or early autumn, setting the root flare at soil level, and water well after planting.

Andean Cedar can spread to about 20 ft (6.1 m) and reach about 50 ft (15 m) tall. Space plants about 20 ft (6.1 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune Andean Cedar while it is dormant in late winter: first remove dead, damaged and crossing branches, then thin lightly for shape.

If it flowers in spring, prune right after flowering instead so you don't remove next year's buds. Never take off more than about a quarter of the tree in one year.

Andean Cedar is frost-tender (hardy to USDA zone 13). In colder areas grow it in a container and move it to a bright, frost-free place before the first frost.

Andean Cedar can be propagated through seeds, stem cuttings. Similar propagation techniques also apply to brazilian cedar plant care, which shares the same genus.

Andean Cedar is susceptible to aphids, scale insects, caterpillars. Inspect the foliage regularly, especially along leaf undersides and stems. Treat infestations promptly with insecticidal soap or neem oil to prevent spread.

Andean Cedar grows outdoors in USDA Zone 13a. It survives winters down to planting zone 13a. Andean Cedar is native to South America. In cooler regions, grow Andean Cedar as a houseplant or bring it indoors before the first frost.
