Oligoceras eberhardtii Plant Care

Oligoceras eberhardtii (Oligoceras eberhardtii) belongs to the Euphorbiaceae family within the Oligoceras genus. Oligoceras eberhardtii is native to Vietnam.

Oligoceras eberhardtii displays a tall, upright shrub growth habit, reaching up to 5 ft tall with a spread of approximately 3 ft. Oligoceras eberhardtii produces small clusters of greenish-yellow flowers.

Leaf size: approximately 4 inches.

Water a young or newly planted Oligoceras eberhardtii 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.

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

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

Well-draining sandy loam with added organic matter for moisture retention. Good drainage is essential for Oligoceras eberhardtii to prevent waterlogging, which leads to root rot and fungal issues.

Feed Oligoceras eberhardtii 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 well-draining sandy loam with added organic matter for moisture retention. Avoid low spots where water collects after rain.

Oligoceras eberhardtii 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.

Oligoceras eberhardtii can spread to about 3 ft (0.9 m) and reach about 5 ft (2 m) tall. Space plants about 3 ft (0.9 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune Oligoceras eberhardtii 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.

Oligoceras eberhardtii 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.

Oligoceras eberhardtii can be propagated through seeds, stem cuttings.

Oligoceras eberhardtii is susceptible to spider mites, scale insects, mealybugs. Inspect the foliage regularly, especially along leaf undersides and stems. Treat infestations promptly with insecticidal soap or neem oil to prevent spread.

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