Nyasa Trumpetbush Plant Care

Nyasa Trumpetbush (Tecoma nyassae) belongs to the Bignoniaceae family within the Tecoma genus. Nyasa Trumpetbush is native to parts of southern and central Africa.

Nyasa Trumpetbush displays an upright, fast-growing shrub growth habit, reaching up to 6 ft tall with a spread of approximately 4 ft. Nyasa Trumpetbush produces tubular flowers in shades of yellow, orange, or red.

Leaf size: approximately 4 inches.

Water a young or newly planted Nyasa Trumpetbush 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.

Nyasa Trumpetbush thrives in full sun to partial shade.

Tecoma nyassae tolerates temperatures of 50–90°F. Nyasa Trumpetbush prefers humidity levels of 40–70%.

Well-draining sandy loam with added compost for nutrients. Good drainage is essential for Nyasa Trumpetbush to prevent waterlogging, which leads to root rot and fungal issues.

Feed Nyasa Trumpetbush 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 compost for nutrients. Avoid low spots where water collects after rain.

Nyasa Trumpetbush is suited to USDA Zone 9a – 11b.

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.

Nyasa Trumpetbush 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 Nyasa Trumpetbush 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.

Nyasa Trumpetbush is frost-tender (hardy to USDA zone 9). In colder areas grow it in a container and move it to a bright, frost-free place before the first frost.

Nyasa Trumpetbush can be propagated through softwood cuttings, seeds. Similar propagation techniques also apply to orange trumpetbush plant care, which shares the same genus.

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

Nyasa Trumpetbush grows outdoors in USDA Zone 9a – 11b. It survives winters down to planting zone 9a. Nyasa Trumpetbush is native to parts of southern and central Africa. In cooler regions, grow Nyasa Trumpetbush as a houseplant or bring it indoors before the first frost.
