Ottoschulzia rhodoxylon Plant Care

Ottoschulzia rhodoxylon (Ottoschulzia rhodoxylon) belongs to the Icacinaceae family within the Ottoschulzia genus. Ottoschulzia rhodoxylon is native to Puerto Rico and Hispaniola.

Ottoschulzia rhodoxylon displays a tall, upright tree growth habit, reaching up to 15 ft tall with a spread of approximately 8 ft. Ottoschulzia rhodoxylon produces small, inconspicuous greenish flowers.

Leaf size: approximately 6 inches.

Water a young or newly planted Ottoschulzia rhodoxylon 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.

Ottoschulzia rhodoxylon thrives in partial to full shade. The optimal light range is 100–500 lux. Avoid placing Ottoschulzia rhodoxylon in direct, harsh sunlight for extended periods, as this can scorch the foliage.

Ottoschulzia rhodoxylon tolerates temperatures of 60–80°F. Ottoschulzia rhodoxylon prefers humidity levels of 50–80%. A pebble tray or humidifier helps maintain adequate moisture around the plant.

Rich, well-draining loamy soil with added organic matter. Good drainage is essential for Ottoschulzia rhodoxylon to prevent waterlogging, which leads to root rot and fungal issues.

Feed Ottoschulzia rhodoxylon 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 partial to full shade and rich, well-draining loamy soil with added organic matter. Avoid low spots where water collects after rain.

Ottoschulzia rhodoxylon is suited to USDA Zone 13a.

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.

Ottoschulzia rhodoxylon can spread to about 8 ft (2.4 m) and reach about 15 ft (5 m) tall. Space plants about 8 ft (2.4 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune Ottoschulzia rhodoxylon 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.

Ottoschulzia rhodoxylon 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.

Ottoschulzia rhodoxylon can be propagated through seeds, stem cuttings.
