Uvariastrum zenkeri Plant Care

Uvariastrum zenkeri (Uvariastrum zenkeri) belongs to the Annonaceae family within the Uvariastrum genus. Uvariastrum zenkeri is native to Cameroon and Nigeria.

Uvariastrum zenkeri displays a small tree or shrub growth habit, reaching up to 6 ft tall with a spread of approximately 4 ft. Uvariastrum zenkeri produces showy, fragrant flowers in shades of white, yellow, or pink.

Leaf size: approximately 8 inches.

Water a young or newly planted Uvariastrum zenkeri every 7–10 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.

Uvariastrum zenkeri thrives in partial shade to full sun.

Uvariastrum zenkeri tolerates temperatures of 65–85°F. Uvariastrum zenkeri prefers humidity levels of 50–70%. A pebble tray or humidifier helps maintain adequate moisture around the plant.

Well-draining, rich loamy soil with added organic matter like compost. Good drainage is essential for Uvariastrum zenkeri to prevent waterlogging, which leads to root rot and fungal issues.

Feed Uvariastrum zenkeri 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.

Choose a spot with partial shade to full sun and well-draining, rich loamy soil with added organic matter like compost. Avoid low spots where water collects after rain.

Uvariastrum zenkeri is suited to USDA Zone 13b.

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.

Uvariastrum zenkeri can spread to about 4 ft (1.2 m) and reach about 6 ft (2 m) tall. Space plants about 4 ft (1.2 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune Uvariastrum zenkeri 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.

Uvariastrum zenkeri 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.

Uvariastrum zenkeri can be propagated through seeds, stem cuttings.
