Testulea gabonensis Plant Care

Testulea gabonensis (Testulea gabonensis) belongs to the Ochnaceae family within the Testulea genus. Testulea gabonensis is native to Central Africa.

Testulea gabonensis displays a small tree, spreading canopy growth habit, reaching up to 15 ft tall with a spread of approximately 10 ft. Testulea gabonensis produces small, fragrant white flowers in clusters.

Leaf size: approximately 6 inches.

Water a young or newly planted Testulea gabonensis 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.

Testulea gabonensis thrives in partial shade to full sun.

Testulea gabonensis tolerates temperatures of 60–85°F. Testulea gabonensis prefers humidity levels of 50–80%. A pebble tray or humidifier helps maintain adequate moisture around the plant.

Well-draining loamy soil with added organic matter for moisture retention. Good drainage is essential for Testulea gabonensis to prevent waterlogging, which leads to root rot and fungal issues.

Feed Testulea gabonensis 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 loamy soil with added organic matter for moisture retention. Avoid low spots where water collects after rain.

Testulea gabonensis is suited to USDA Zone 11a – 12b.

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.

Testulea gabonensis can spread to about 10 ft (3 m) and reach about 15 ft (5 m) tall. Space plants about 10 ft (3 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune Testulea gabonensis 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.

Testulea gabonensis is frost-tender (hardy to USDA zone 11). In colder areas grow it in a container and move it to a bright, frost-free place before the first frost.

Testulea gabonensis can be propagated through seeds, stem cuttings.

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

Testulea gabonensis grows outdoors in USDA Zone 11a – 12b. It survives winters down to planting zone 11a. Testulea gabonensis is native to Central Africa. In cooler regions, grow Testulea gabonensis as a houseplant or bring it indoors before the first frost.
