Jack's Trumpet Tree Plant Care

Jack's Trumpet Tree (Tabebuia jackiana) belongs to the Bignoniaceae family within the Tabebuia genus. Jack's Trumpet Tree is native to Cuba.

Jack's Trumpet Tree displays a tall, upright tree growth habit, reaching up to 30 ft tall with a spread of approximately 20 ft. Jack's Trumpet Tree produces showy trumpet-shaped flowers in various colors.

Leaf size: approximately 6 inches.

Water a young or newly planted Jack's Trumpet Tree 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.

Jack's Trumpet Tree thrives in full sun.

Tabebuia jackiana tolerates temperatures of 60–85°F. Jack's Trumpet Tree prefers humidity levels of 40–70%.

Well-draining sandy soil with some organic matter. Good drainage is essential for Jack's Trumpet Tree to prevent waterlogging, which leads to root rot and fungal issues.

Feed Jack's Trumpet Tree 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 and well-draining sandy soil with some organic matter. Avoid low spots where water collects after rain.

Jack's Trumpet Tree is suited to USDA Zone 13a.

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.

Jack's Trumpet Tree can spread to about 20 ft (6.1 m) and reach about 30 ft (9 m) tall. Space plants about 20 ft (6.1 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune Jack's Trumpet Tree 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.

Jack's Trumpet Tree 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.

Jack's Trumpet Tree can be propagated through seeds, stem cuttings. Similar propagation techniques also apply to pink trumpet tree plant care, which shares the same genus.
