Sebastiania klotzschiana Plant Care

Sebastiania klotzschiana (Sebastiania klotzschiana) belongs to the Euphorbiaceae family within the Sebastiania genus. Sebastiania klotzschiana is native to Brazil and northern Argentina.

Sebastiania klotzschiana displays an upright, branching shrub growth habit, reaching up to 4 ft tall with a spread of approximately 3 ft. Sebastiania klotzschiana produces small greenish flowers in clusters.

Leaf size: approximately 5 inches.

Water a young or newly planted Sebastiania klotzschiana 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.

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

Sebastiania klotzschiana tolerates temperatures of 65–80°F. Sebastiania klotzschiana 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. Good drainage is essential for Sebastiania klotzschiana to prevent waterlogging, which leads to root rot and fungal issues.

Feed Sebastiania klotzschiana 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 sandy loam with added organic matter. Avoid low spots where water collects after rain.

Sebastiania klotzschiana 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.

Sebastiania klotzschiana can spread to about 3 ft (0.9 m) and reach about 4 ft (1 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 Sebastiania klotzschiana 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.

Sebastiania klotzschiana 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.

Sebastiania klotzschiana can be propagated through seeds, stem cuttings. Similar propagation techniques also apply to sebastiania argutidens plant care, which shares the same genus.

Sebastiania klotzschiana grows outdoors in USDA Zone 13b. It survives winters down to planting zone 13b. Sebastiania klotzschiana is native to Brazil and northern Argentina. In cooler regions, grow Sebastiania klotzschiana as a houseplant or bring it indoors before the first frost.
