Machaonia erythrocarpa Plant Care

Machaonia erythrocarpa (Machaonia erythrocarpa) belongs to the Rubiaceae family within the Machaonia genus.

Machaonia erythrocarpa displays a compact, bushy shrub growth habit, reaching up to 2.5 ft tall with a spread of approximately 2.5 ft. Machaonia erythrocarpa produces small, fragrant white flowers in clusters.

Leaf size: approximately 4 inches.

Water a young or newly planted Machaonia erythrocarpa 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.

Machaonia erythrocarpa thrives in bright indirect light. Avoid placing Machaonia erythrocarpa in direct, harsh sunlight for extended periods, as this can scorch the foliage.

Machaonia erythrocarpa tolerates temperatures of 65–80°F. Machaonia erythrocarpa prefers humidity levels of 50–70%. A pebble tray or humidifier helps maintain adequate moisture around the plant.

Rich, well-draining soil with added organic matter like compost or peat moss. Good drainage is essential for Machaonia erythrocarpa to prevent waterlogging, which leads to root rot and fungal issues.

Feed Machaonia erythrocarpa 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.

The PlantoScan app can remind you when to water and when to fertilize each plant.

Choose a spot with bright indirect light and rich, well-draining soil with added organic matter like compost or peat moss. Avoid low spots where water collects after rain.

Machaonia erythrocarpa is suited to USDA Zone 13b.

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.

Machaonia erythrocarpa can spread to about 3 ft (0.8 m) and reach about 3 ft (1 m) tall. Space plants about 3 ft (0.8 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune Machaonia erythrocarpa 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.

Machaonia erythrocarpa 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.

Machaonia erythrocarpa can be propagated through softwood cuttings, air layering. Similar propagation techniques also apply to woodbury's tassel flower plant care, which shares the same genus.

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

Machaonia erythrocarpa grows outdoors in USDA Zone 13b. It survives winters down to planting zone 13b. In cooler regions, grow Machaonia erythrocarpa as a houseplant or bring it indoors before the first frost.
