Polyscias tahitensis Plant Care

Polyscias tahitensis (Polyscias tahitensis) belongs to the Araliaceae family within the Polyscias genus. Polyscias tahitensis is native to the islands of Tahiti and Raiatea in the Society Islands of French Polynesia.

Polyscias tahitensis displays an upright, bushy shrub growth habit, reaching up to 4 ft tall with a spread of approximately 3 ft. Polyscias tahitensis produces small inconspicuous flowers.

Leaf size: approximately 6 inches.

Water a young or newly planted Polyscias tahitensis every 7–10 days, soaking the whole root zone, until it is established — usually one to two growing seasons. Established shrubs mainly need water during long dry spells. In a container, water whenever the top few centimetres of soil are dry.

Polyscias tahitensis thrives in bright indirect light. Avoid placing Polyscias tahitensis in direct, harsh sunlight for extended periods, as this can scorch the foliage.

Polyscias tahitensis tolerates temperatures of 65–80°F. Polyscias tahitensis prefers humidity levels of 50–70%. A pebble tray or humidifier helps maintain adequate moisture around the plant.

Well-draining potting mix rich in organic matter. Good drainage is essential for Polyscias tahitensis to prevent waterlogging, which leads to root rot and fungal issues.

Feed Polyscias tahitensis every 4 months during the growing season with a balanced, slow-release fertilizer at the rate on the label. Established shrubs 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.

The PlantoScan app can remind you when to water and when to fertilize each plant.

Choose a spot with bright indirect light and well-draining potting mix rich in organic matter. Avoid low spots where water collects after rain.

Polyscias tahitensis is suited to USDA Zone 11a – 12b.

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

Polyscias tahitensis can spread to about 3 ft (0.9 m) and reach about 4 ft (1 m) tall. Space plants about 3 ft (0.9 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune Polyscias tahitensis 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 shrub in one year.

Polyscias tahitensis is frost-tender (hardy to USDA zone 11). In colder areas grow it in a container and move it to a bright, frost-free place before the first frost.

Polyscias tahitensis can be propagated through stem cuttings, air layering. Similar propagation techniques also apply to balfour aralia plant care, which shares the same genus.

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

Polyscias tahitensis grows outdoors in USDA Zone 11a – 12b. It survives winters down to planting zone 11a. Polyscias tahitensis is native to the islands of Tahiti and Raiatea in the Society Islands of French Polynesia. In cooler regions, grow Polyscias tahitensis as a houseplant or bring it indoors before the first frost.
