Hooker's Agrostistachys Plant Care

Hooker's Agrostistachys (Agrostistachys hookeri) belongs to the Euphorbiaceae family within the Agrostistachys genus. Hooker's Agrostistachys is native to Sri Lanka.

Hooker's Agrostistachys displays a tall, upright tree growth habit, reaching up to 30 ft tall with a spread of approximately 15 ft. Hooker's Agrostistachys produces small greenish flowers in clusters.

Leaf size: approximately 6 inches.

Water a young or newly planted Hooker's Agrostistachys 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.

Hooker's Agrostistachys thrives in full sun to partial shade.

Agrostistachys hookeri tolerates temperatures of 65–85°F. Hooker's Agrostistachys prefers humidity levels of 50–70%. A pebble tray or humidifier helps maintain adequate moisture around the plant.

Well-draining sandy loam with added organic matter for moisture retention. Good drainage is essential for Hooker's Agrostistachys to prevent waterlogging, which leads to root rot and fungal issues.

Feed Hooker's Agrostistachys 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.

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

Choose a spot with full sun to partial shade and well-draining sandy loam with added organic matter for moisture retention. Avoid low spots where water collects after rain.

Hooker's Agrostistachys is suited to USDA Zone 11a – 12b.

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.

Hooker's Agrostistachys can spread to about 15 ft (4.6 m) and reach about 30 ft (9 m) tall. Space plants about 15 ft (4.6 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune Hooker's Agrostistachys 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.

Hooker's Agrostistachys 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.

Hooker's Agrostistachys can be propagated through seeds, stem cuttings. Similar propagation techniques also apply to agrostistachys borneensis plant care, which shares the same genus.
