Rhopalocarpus macrorhamnifolius Plant Care

Rhopalocarpus macrorhamnifolius (Rhopalocarpus macrorhamnifolius) belongs to the Sphaerosepalaceae family within the Rhopalocarpus genus. Rhopalocarpus macrorhamnifolius is native to Madagascar.

Rhopalocarpus macrorhamnifolius displays a tall, slender tree growth habit, reaching up to 10 ft tall with a spread of approximately 5 ft. Rhopalocarpus macrorhamnifolius produces small, fragrant white flowers in clusters.

Leaf size: approximately 4 inches.

Water a young or newly planted Rhopalocarpus macrorhamnifolius every 7–10 days, soaking the whole root zone, until it is established — usually one to two growing seasons. Established trees mainly need water during long dry spells. In a container, water whenever the top few centimetres of soil are dry.

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

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

Loamy, well-draining soil mix with added peat moss and perlite. Good drainage is essential for Rhopalocarpus macrorhamnifolius to prevent waterlogging, which leads to root rot and fungal issues.

Feed Rhopalocarpus macrorhamnifolius every 6 months during the growing season with a balanced, slow-release fertilizer at the rate on the label. Established trees 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 bright indirect light and loamy, well-draining soil mix with added peat moss and perlite. Avoid low spots where water collects after rain.

Rhopalocarpus macrorhamnifolius is suited to USDA Zone 13b.

Plant container-grown or balled-and-burlapped trees in spring or early autumn, setting the root flare at soil level, and water well after planting.

Rhopalocarpus macrorhamnifolius can spread to about 5 ft (1.5 m) and reach about 10 ft (3 m) tall. Space plants about 5 ft (1.5 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune Rhopalocarpus macrorhamnifolius 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 tree in one year.

Rhopalocarpus macrorhamnifolius 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.

Rhopalocarpus macrorhamnifolius can be propagated through seeds, stem cuttings. Similar propagation techniques also apply to louvel's butterfly tree plant care, which shares the same genus.
