Narrowleaf Aglaia Plant Care

Narrowleaf Aglaia (Aglaia angustifolia) belongs to the Meliaceae family within the Aglaia genus. Narrowleaf Aglaia is native to Brunei, Indonesia, Malaysia, and the Philippines.

Narrowleaf Aglaia displays a compact, bushy shrub growth habit, reaching up to 3 ft tall with a spread of approximately 2 ft. Narrowleaf Aglaia produces small, fragrant clusters of yellow flowers.

Leaf size: approximately 4 inches.

Water a young or newly planted Narrowleaf Aglaia 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.

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

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

Well-draining, fertile soil with added organic matter. Good drainage is essential for Narrowleaf Aglaia to prevent waterlogging, which leads to root rot and fungal issues.

Feed Narrowleaf Aglaia every 6 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, fertile soil with added organic matter. Avoid low spots where water collects after rain.

Narrowleaf Aglaia 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.

Narrowleaf Aglaia can spread to about 2 ft (0.6 m) and reach about 3 ft (1 m) tall. Space plants about 2 ft (0.6 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune Narrowleaf Aglaia 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.

Narrowleaf Aglaia 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.

Narrowleaf Aglaia can be propagated through seeds, stem cuttings.

Narrowleaf Aglaia 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.

Narrowleaf Aglaia grows outdoors in USDA Zone 13b. It survives winters down to planting zone 13b. Narrowleaf Aglaia is native to Brunei, Indonesia, Malaysia, and the Philippines. In cooler regions, grow Narrowleaf Aglaia as a houseplant or bring it indoors before the first frost.
