Colliguaja Plant Care

Colliguaja (Colliguaja odorifera) belongs to the Euphorbiaceae family within the Colliguaja genus. Colliguaja is native to the same forest as the endangered Chilean Wine Palm.

Colliguaja displays a small tree or shrub growth habit, reaching up to 10 ft tall with a spread of approximately 8 ft. Colliguaja produces small, inconspicuous flowers.

Leaf size: approximately 3 inches.

Water a young or newly planted Colliguaja 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.

Colliguaja thrives in full sun to partial shade.

Colliguaja odorifera tolerates temperatures of 50–85°F. Colliguaja prefers humidity levels of 40–70%.

Well-draining sandy soil mix with good organic content. Good drainage is essential for Colliguaja to prevent waterlogging, which leads to root rot and fungal issues.

Feed Colliguaja 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 sandy soil mix with good organic content. Avoid low spots where water collects after rain.

Colliguaja is suited to USDA Zone 12a.

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.

Colliguaja can spread to about 8 ft (2.4 m) and reach about 10 ft (3 m) tall. Space plants about 8 ft (2.4 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune Colliguaja 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.

Colliguaja is frost-tender (hardy to USDA zone 12). In colder areas grow it in a container and move it to a bright, frost-free place before the first frost.

Colliguaja can be propagated through seeds, stem cuttings.

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

Colliguaja grows outdoors in USDA Zone 12a. It survives winters down to planting zone 12a. Colliguaja is native to the same forest as the endangered Chilean Wine Palm. In cooler regions, grow Colliguaja as a houseplant or bring it indoors before the first frost.
