Arnhem Hop Bush Plant Care

Arnhem Hop Bush (Dodonaea arnhemica) belongs to the Sapindaceae family within the Dodonaea genus. Arnhem Hop Bush is native to the north of the Northern Territory.

Arnhem Hop Bush displays an upright, bushy shrub growth habit, reaching up to 6 ft tall with a spread of approximately 4 ft. Arnhem Hop Bush produces inconspicuous small greenish flowers.

Leaf size: approximately 3 inches.

Water a young or newly planted Arnhem Hop Bush 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.

Arnhem Hop Bush thrives in full sun to partial shade.

Dodonaea arnhemica tolerates temperatures of 50–85°F. Arnhem Hop Bush prefers humidity levels of 40–70%.

Well-draining sandy loam with added organic matter. Good drainage is essential for Arnhem Hop Bush to prevent waterlogging, which leads to root rot and fungal issues.

Feed Arnhem Hop Bush 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 loam with added organic matter. Avoid low spots where water collects after rain.

Arnhem Hop Bush 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.

Arnhem Hop Bush can spread to about 4 ft (1.2 m) and reach about 6 ft (2 m) tall. Space plants about 4 ft (1.2 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune Arnhem Hop Bush 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.

Arnhem Hop Bush 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.

Arnhem Hop Bush can be propagated through seeds, stem cuttings. Similar propagation techniques also apply to adenophora hop bush plant care, which shares the same genus.
