Jatropha unicostata Plant Care

Jatropha unicostata (Jatropha unicostata) belongs to the Euphorbiaceae family within the Jatropha genus. Jatropha unicostata is native to Socotra island Yemen.

Jatropha unicostata displays a small tree, shrub growth habit, reaching up to 10 ft tall with a spread of approximately 8 ft. Jatropha unicostata produces small clusters of red, pink, or white flowers.

Leaf size: approximately 6 inches.

Water a young or newly planted Jatropha unicostata 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.

Jatropha unicostata thrives in full sun to partial shade.

Jatropha unicostata tolerates temperatures of 60–90°F. Jatropha unicostata prefers humidity levels of 40–70%.

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

Feed Jatropha unicostata 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.

The PlantoScan app can remind you when to water and when to fertilize each plant.

Choose a spot with full sun to partial shade and well-draining sandy loam with added organic matter. Avoid low spots where water collects after rain.

Jatropha unicostata is suited to USDA Zone 10b – 12b.

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.

Jatropha unicostata can spread to about 8 ft (2.4 m) and reach about 10 ft (3 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 Jatropha unicostata 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.

Jatropha unicostata is frost-tender (hardy to USDA zone 10). In colder areas grow it in a container and move it to a bright, frost-free place before the first frost.

Jatropha unicostata can be propagated through stem cuttings, seeds. Similar propagation techniques also apply to physic nut plant care, which shares the same genus.

Jatropha unicostata is susceptible to aphids, spider mites, whiteflies. Inspect the foliage regularly, especially along leaf undersides and stems. Treat infestations promptly with insecticidal soap or neem oil to prevent spread.

Jatropha unicostata grows outdoors in USDA Zone 10b – 12b. It survives winters down to planting zone 10b. Jatropha unicostata is native to Socotra island Yemen. In cooler regions, grow Jatropha unicostata as a houseplant or bring it indoors before the first frost.
