Stillingia oppositifolia Plant Care

Stillingia oppositifolia (Stillingia oppositifolia) belongs to the Euphorbiaceae family within the Stillingia genus. Stillingia oppositifolia is native to Brazil.

Stillingia oppositifolia displays an upright, branching shrub growth habit, reaching up to 4 ft tall with a spread of approximately 3 ft. Stillingia oppositifolia produces small greenish flowers in dense spikes.

Leaf size: approximately 4 inches.

Water a young or newly planted Stillingia oppositifolia every 7–14 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.

Stillingia oppositifolia thrives in full sun to partial shade.

Stillingia oppositifolia tolerates temperatures of 60–85°F. Stillingia oppositifolia prefers humidity levels of 40–70%.

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

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

Stillingia oppositifolia is suited to USDA Zone 13a.

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.

Stillingia oppositifolia 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 Stillingia oppositifolia 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.

Stillingia oppositifolia 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.

Stillingia oppositifolia can be propagated through seeds, stem cuttings. Similar propagation techniques also apply to pencil cactus plant care, which shares the same genus.

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

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