Sladenia celastrifolia Plant Care

Sladenia celastrifolia (Sladenia celastrifolia) belongs to the Sladeniaceae family within the Sladenia genus. Sladenia celastrifolia is native to southwestern China, Thailand, and Myanmar.

Sladenia celastrifolia displays a compact, spreading shrub growth habit, reaching up to 2.5 ft tall with a spread of approximately 3 ft. Sladenia celastrifolia produces small, fragrant white flowers in clusters.

Leaf size: approximately 4 inches.

Water a young or newly planted Sladenia celastrifolia 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.

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

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

Loamy, well-draining soil with added compost for nutrients. Good drainage is essential for Sladenia celastrifolia to prevent waterlogging, which leads to root rot and fungal issues.

Feed Sladenia celastrifolia 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 loamy, well-draining soil with added compost for nutrients. Avoid low spots where water collects after rain.

Sladenia celastrifolia 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.

Sladenia celastrifolia can spread to about 3 ft (0.9 m) and reach about 3 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 Sladenia celastrifolia 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.

Sladenia celastrifolia 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.

Sladenia celastrifolia can be propagated through leaf cuttings, division, air layering. Similar propagation techniques also apply to sladenia integrifolia plant care, which shares the same genus.

Sladenia celastrifolia 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.

Sladenia celastrifolia grows outdoors in USDA Zone 13b. It survives winters down to planting zone 13b. Sladenia celastrifolia is native to southwestern China, Thailand, and Myanmar. In cooler regions, grow Sladenia celastrifolia as a houseplant or bring it indoors before the first frost.
