Paranecepsia alchorneifolia Plant Care

Paranecepsia alchorneifolia (Paranecepsia alchorneifolia) belongs to the Euphorbiaceae family within the Paranecepsia genus. Paranecepsia alchorneifolia is native to southeastern Africa.

Paranecepsia alchorneifolia displays a tall, slender tree growth habit, reaching up to 10 ft tall with a spread of approximately 5 ft. Paranecepsia alchorneifolia produces small, inconspicuous greenish-yellow flowers.

Leaf size: approximately 4 inches.

Water a young or newly planted Paranecepsia alchorneifolia 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.

Paranecepsia alchorneifolia thrives in full sun to partial shade.

Paranecepsia alchorneifolia tolerates temperatures of 65–85°F. Paranecepsia alchorneifolia prefers humidity levels of 40–70%.

Loamy, well-draining soil mix with added organic matter like compost. Good drainage is essential for Paranecepsia alchorneifolia to prevent waterlogging, which leads to root rot and fungal issues.

Feed Paranecepsia alchorneifolia 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 full sun to partial shade and loamy, well-draining soil mix with added organic matter like compost. Avoid low spots where water collects after rain.

Paranecepsia alchorneifolia 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.

Paranecepsia alchorneifolia can spread to about 5 ft (1.5 m) and reach about 10 ft (3 m) tall. Space plants about 5 ft (1.5 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune Paranecepsia alchorneifolia 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.

Paranecepsia alchorneifolia 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.

Paranecepsia alchorneifolia can be propagated through stem cuttings, air layering.
