Polyscias gracilis Plant Care

Polyscias gracilis (Polyscias gracilis) belongs to the Araliaceae family within the Polyscias genus. Polyscias gracilis is native to Mauritius.

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

Leaf size: approximately 6 inches.

Water a young or newly planted Polyscias gracilis 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 gracilis thrives in bright indirect light. Avoid placing Polyscias gracilis in direct, harsh sunlight for extended periods, as this can scorch the foliage.

Polyscias gracilis tolerates temperatures of 65–80°F. Polyscias gracilis 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 gracilis to prevent waterlogging, which leads to root rot and fungal issues.

Feed Polyscias gracilis 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.

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 gracilis is suited to USDA Zone 13b.

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 gracilis 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 gracilis 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 gracilis 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.

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

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