Duckeanthus grandiflorus Plant Care

Duckeanthus grandiflorus (Duckeanthus grandiflorus) belongs to the Annonaceae family within the Duckeanthus genus. Duckeanthus grandiflorus is native to Brazil.

Duckeanthus grandiflorus displays a small tree, spreading canopy growth habit, reaching up to 15 ft tall with a spread of approximately 10 ft. Duckeanthus grandiflorus produces fragrant, yellow flowers with multiple petals.

Leaf size: approximately 6 inches.

Water a young or newly planted Duckeanthus grandiflorus 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.

Duckeanthus grandiflorus thrives in partial shade to full sun.

Duckeanthus grandiflorus tolerates temperatures of 65–85°F. Duckeanthus grandiflorus prefers humidity levels of 50–80%. A pebble tray or humidifier helps maintain adequate moisture around the plant.

Rich, well-draining soil with high organic matter content. Good drainage is essential for Duckeanthus grandiflorus to prevent waterlogging, which leads to root rot and fungal issues.

Feed Duckeanthus grandiflorus 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 rich, well-draining soil with high organic matter content. Avoid low spots where water collects after rain.

Duckeanthus grandiflorus 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.

Duckeanthus grandiflorus 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 Duckeanthus grandiflorus 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.

Duckeanthus grandiflorus 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.

Duckeanthus grandiflorus can be propagated through air layering, stem cuttings.
