White Tabernaemontana Plant Care

White Tabernaemontana (Tabernaemontana alba) belongs to the Apocynaceae family within the Tabernaemontana genus. White Tabernaemontana is native to Central America, Mexico, Cuba, and Colombia.

White Tabernaemontana displays an upright, bushy shrub growth habit, reaching up to 3 ft tall with a spread of approximately 2 ft. White Tabernaemontana produces fragrant white flowers in clusters.

Leaf size: approximately 5 inches.

Water a young or newly planted White Tabernaemontana 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.

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

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

Well-draining, fertile soil with added perlite for extra drainage. Good drainage is essential for White Tabernaemontana to prevent waterlogging, which leads to root rot and fungal issues.

Feed White Tabernaemontana 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, fertile soil with added perlite for extra drainage. Avoid low spots where water collects after rain.

White Tabernaemontana 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.

White Tabernaemontana can spread to about 2 ft (0.6 m) and reach about 3 ft (1 m) tall. Space plants about 2 ft (0.6 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune White Tabernaemontana 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.

White Tabernaemontana 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.

White Tabernaemontana can be propagated through stem cuttings, air layering. Similar propagation techniques also apply to african dogwood plant care, which shares the same genus.

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

White Tabernaemontana grows outdoors in USDA Zone 13b. It survives winters down to planting zone 13b. White Tabernaemontana is native to Central America, Mexico, Cuba, and Colombia. In cooler regions, grow White Tabernaemontana as a houseplant or bring it indoors before the first frost.
