Atractocarpus merikin Plant Care

Atractocarpus merikin (Atractocarpus merikin) belongs to the Rubiaceae family within the Atractocarpus genus. Atractocarpus merikin is native to northeast Queensland, Australia.

Atractocarpus merikin displays a compact, bushy shrub growth habit, reaching up to 2.5 ft tall with a spread of approximately 2.5 ft. Atractocarpus merikin produces small, white, star-shaped flowers in clusters.

Leaf size: approximately 4 inches.

Water a young or newly planted Atractocarpus merikin 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.

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

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

Well-draining, acidic soil with high organic content. Good drainage is essential for Atractocarpus merikin to prevent waterlogging, which leads to root rot and fungal issues.

Feed Atractocarpus merikin 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 well-draining, acidic soil with high organic content. Avoid low spots where water collects after rain.

Atractocarpus merikin 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.

Atractocarpus merikin 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 Atractocarpus merikin 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.

Atractocarpus merikin 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.

Atractocarpus merikin can be propagated through seeds, stem cuttings. Similar propagation techniques also apply to atractocarpus benthamianus plant care, which shares the same genus.

Atractocarpus merikin 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.

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