Pleodendron macranthum Plant Care

Pleodendron macranthum (Pleodendron macranthum) belongs to the Canellaceae family within the Pleodendron genus. Pleodendron macranthum is native to Puerto Rico.

Pleodendron macranthum displays a tall, upright tree growth habit, reaching up to 10 ft tall with a spread of approximately 5 ft. Pleodendron macranthum produces small, inconspicuous flowers.

Leaf size: approximately 6 inches.

Water a young or newly planted Pleodendron macranthum every 7–14 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.

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

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

Rich, well-draining soil with high organic content. Good drainage is essential for Pleodendron macranthum to prevent waterlogging, which leads to root rot and fungal issues.

Feed Pleodendron macranthum 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 rich, well-draining soil with high organic content. Avoid low spots where water collects after rain.

Pleodendron macranthum 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.

Pleodendron macranthum 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 Pleodendron macranthum 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.

Pleodendron macranthum 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.

Pleodendron macranthum can be propagated through seeds, stem cuttings.

Pleodendron macranthum 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.

Pleodendron macranthum grows outdoors in USDA Zone 13b. It survives winters down to planting zone 13b. Pleodendron macranthum is native to Puerto Rico. In cooler regions, grow Pleodendron macranthum as a houseplant or bring it indoors before the first frost.
