Pink Trumpet Tree Plant Care

Pink Trumpet Tree (Spirotheca rosea) belongs to the Malvaceae family within the Spirotheca genus.

Pink Trumpet Tree displays a tall tree with spreading canopy growth habit, reaching up to 30 ft tall with a spread of approximately 20 ft. Pink Trumpet Tree produces large showy flowers in shades of pink, red, or white.

Leaf size: approximately 8 inches.

Water a young or newly planted Pink 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.

Pink Trumpet Tree thrives in full sun to partial shade.

Spirotheca rosea tolerates temperatures of 65–85°F. Pink Trumpet Tree prefers humidity levels of 50–80%. A pebble tray or humidifier helps maintain adequate moisture around the plant.

Well-draining loamy soil with added compost for nutrients. Good drainage is essential for Pink Trumpet Tree to prevent waterlogging, which leads to root rot and fungal issues.

Feed Pink 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 to partial shade and well-draining loamy soil with added compost for nutrients. Avoid low spots where water collects after rain.

Pink Trumpet Tree 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.

Pink 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 Pink 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.

Pink 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.

Pink Trumpet Tree can be propagated through seeds, air layering.
