Rawsonia burtt-davyi displays a tall, slender tree growth habit, reaching up to 15 ft tall with a spread of approximately 8 ft. Rawsonia burtt-davyi produces small, fragrant white flowers in clusters.

Leaf size: approximately 6 inches.

Water a young or newly planted Rawsonia burtt-davyi every 7–10 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.

Rawsonia burtt-davyi thrives in full sun to partial shade.

Rawsonia burtt-davyi tolerates temperatures of 65–85°F. Rawsonia burtt-davyi prefers humidity levels of 50–70%. A pebble tray or humidifier helps maintain adequate moisture around the plant.

Well-draining loamy soil with added compost for nutrients. Good drainage is essential for Rawsonia burtt-davyi to prevent waterlogging, which leads to root rot and fungal issues.

Feed Rawsonia burtt-davyi 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 loamy soil with added compost for nutrients. Avoid low spots where water collects after rain.

Rawsonia burtt-davyi is suited to USDA Zone 13b.

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.

Rawsonia burtt-davyi can spread to about 8 ft (2.4 m) and reach about 15 ft (5 m) tall. Space plants about 8 ft (2.4 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune Rawsonia burtt-davyi 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.

Rawsonia burtt-davyi 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.

Rawsonia burtt-davyi can be propagated through seeds, stem cuttings. Similar propagation techniques also apply to false cucumber plant care, which shares the same genus.
