Macgregoria racemigera Plant Care

Macgregoria racemigera (Macgregoria racemigera) belongs to the Celastraceae family within the Macgregoria genus. Macgregoria racemigera is native to inland Australia from New South Wales through Queensland, the Northern Territory to Western Australia, and South Australia.

Macgregoria racemigera displays a compact, spreading shrub growth habit, reaching up to 2.5 ft tall with a spread of approximately 3 ft. Macgregoria racemigera produces small clusters of white, star-shaped flowers.

Leaf size: approximately 4 inches.

Water a young or newly planted Macgregoria racemigera 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.

Macgregoria racemigera thrives in partial shade to full sun.

Macgregoria racemigera tolerates temperatures of 60–80°F. Macgregoria racemigera prefers humidity levels of 40–70%.

Well-draining sandy soil with added organic matter for nutrients. Good drainage is essential for Macgregoria racemigera to prevent waterlogging, which leads to root rot and fungal issues.

Feed Macgregoria racemigera 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 partial shade to full sun and well-draining sandy soil with added organic matter for nutrients. Avoid low spots where water collects after rain.

Macgregoria racemigera 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.

Macgregoria racemigera can spread to about 3 ft (0.9 m) and reach about 3 ft (1 m) tall. Space plants about 3 ft (0.9 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune Macgregoria racemigera 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.

Macgregoria racemigera 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.

Macgregoria racemigera can be propagated through seeds, stem cuttings.

Macgregoria racemigera is susceptible to aphids, scale insects, spider mites. Inspect the foliage regularly, especially along leaf undersides and stems. Treat infestations promptly with insecticidal soap or neem oil to prevent spread.

Macgregoria racemigera grows outdoors in USDA Zone 13a. It survives winters down to planting zone 13a. Macgregoria racemigera is native to inland Australia from New South Wales through Queensland, the Northern Territory to Western Australia, and South Australia. In cooler regions, grow Macgregoria racemigera as a houseplant or bring it indoors before the first frost.
