Stockwellia quadrifida Plant Care

Stockwellia quadrifida (Stockwellia quadrifida) belongs to the Myrtaceae family within the Stockwellia genus. Stockwellia quadrifida is native to Queensland.

Stockwellia quadrifida displays a compact, upright shrub growth habit, reaching up to 3 ft tall with a spread of approximately 2 ft. Stockwellia quadrifida produces small white fragrant flowers in clusters.

Leaf size: approximately 4 inches.

Water a young or newly planted Stockwellia quadrifida 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.

Stockwellia quadrifida thrives in full sun to partial shade.

Stockwellia quadrifida tolerates temperatures of 60–80°F. Stockwellia quadrifida 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 Stockwellia quadrifida to prevent waterlogging, which leads to root rot and fungal issues.

Feed Stockwellia quadrifida 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 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.

Stockwellia quadrifida is suited to USDA Zone 13a.

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.

Stockwellia quadrifida 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 Stockwellia quadrifida 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.

Stockwellia quadrifida 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.

Stockwellia quadrifida can be propagated through seeds, softwood cuttings.

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