Strychnos chromatoxylon Plant Care

Strychnos chromatoxylon (Strychnos chromatoxylon) belongs to the Loganiaceae family within the Strychnos genus. Strychnos chromatoxylon is native to Cameroon, Central African Republic, and Ivory Coast.

Strychnos chromatoxylon displays a small tree or shrub growth habit, reaching up to 10 ft tall with a spread of approximately 8 ft. Strychnos chromatoxylon produces small, fragrant white flowers.

Leaf size: approximately 4 inches.

Water a young or newly planted Strychnos chromatoxylon 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.

Strychnos chromatoxylon thrives in full sun to partial shade.

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

Well-draining sandy loam with added organic matter. Good drainage is essential for Strychnos chromatoxylon to prevent waterlogging, which leads to root rot and fungal issues.

Feed Strychnos chromatoxylon 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 well-draining sandy loam with added organic matter. Avoid low spots where water collects after rain.

Strychnos chromatoxylon 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.

Strychnos chromatoxylon can spread to about 8 ft (2.4 m) and reach about 10 ft (3 m) tall. Space plants about 8 ft (2.4 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune Strychnos chromatoxylon 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.

Strychnos chromatoxylon 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.

Strychnos chromatoxylon can be propagated through seeds, stem cuttings. Similar propagation techniques also apply to icaco plant care, which shares the same genus.

Strychnos chromatoxylon 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.

Strychnos chromatoxylon grows outdoors in USDA Zone 13b. It survives winters down to planting zone 13b. Strychnos chromatoxylon is native to Cameroon, Central African Republic, and Ivory Coast. In cooler regions, grow Strychnos chromatoxylon as a houseplant or bring it indoors before the first frost.
