Spatulate-leaf Stackhousia Plant Care

Spatulate-leaf Stackhousia (Stackhousia spathulata) belongs to the Celastraceae family within the Stackhousia genus. Spatulate-leaf Stackhousia is native to heath and dry sclerophyll forest in sandy areas, often near beaches or lagoons in southeastern Australia.

Spatulate-leaf Stackhousia displays a low rosette, spreading ground cover growth habit, reaching up to 0.5 ft tall with a spread of approximately 1 ft. Spatulate-leaf Stackhousia produces small white or pink clustered flowers.

Leaf size: approximately 2 inches.

Water a young or newly planted Spatulate-leaf Stackhousia 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.

Spatulate-leaf Stackhousia thrives in full sun to partial shade.

Stackhousia spathulata tolerates temperatures of 50–80°F. Spatulate-leaf Stackhousia prefers humidity levels of 40–70%.

Well-draining sandy soil with added organic matter for moisture retention. Good drainage is essential for Spatulate-leaf Stackhousia to prevent waterlogging, which leads to root rot and fungal issues.

Feed Spatulate-leaf Stackhousia 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 soil with added organic matter for moisture retention. Avoid low spots where water collects after rain.

Spatulate-leaf Stackhousia is suited to USDA Zone 12a.

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.

Spatulate-leaf Stackhousia can spread to about 1 ft (0.3 m) and reach about 1 ft (0 m) tall. Space plants about 1 ft (0.3 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune Spatulate-leaf Stackhousia 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.

Spatulate-leaf Stackhousia 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.

Spatulate-leaf Stackhousia can be propagated through seeds, division of offsets. Similar propagation techniques also apply to tiny stackhousia plant care, which shares the same genus.

Spatulate-leaf Stackhousia is susceptible to aphids, spider mites, whiteflies. Inspect the foliage regularly, especially along leaf undersides and stems. Treat infestations promptly with insecticidal soap or neem oil to prevent spread.

Spatulate-leaf Stackhousia grows outdoors in USDA Zone 12a. It survives winters down to planting zone 12a. Spatulate-leaf Stackhousia is native to heath and dry sclerophyll forest in sandy areas, often near beaches or lagoons in southeastern Australia. In cooler regions, grow Spatulate-leaf Stackhousia as a houseplant or bring it indoors before the first frost.
