Fourpetal Pawpaw Plant Care

Fourpetal Pawpaw (Asimina obovata) belongs to the Annonaceae family within the Asimina genus. Fourpetal Pawpaw is native to Florida. Fourpetal Pawpaw is also known as Bigflower Pawpaw.

Fourpetal Pawpaw displays a small tree or shrub growth habit, reaching up to 20 ft tall with a spread of approximately 15 ft. Fourpetal Pawpaw produces large, unique, maroon flowers.

Leaf size: approximately 6 inches.

Water a young or newly planted Fourpetal Pawpaw 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.

Fourpetal Pawpaw thrives in full sun to part shade.

Asimina obovata tolerates temperatures of 50–90°F. Fourpetal Pawpaw prefers humidity levels of 40–70%.

Rich, well-draining loamy soil with added organic matter. Good drainage is essential for Fourpetal Pawpaw to prevent waterlogging, which leads to root rot and fungal issues.

Feed Fourpetal Pawpaw 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 part shade and rich, well-draining loamy soil with added organic matter. Avoid low spots where water collects after rain.

Fourpetal Pawpaw is suited to USDA Zone 12a.

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.

Fourpetal Pawpaw can spread to about 15 ft (4.6 m) and reach about 20 ft (6 m) tall. Space plants about 15 ft (4.6 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune Fourpetal Pawpaw 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.

Fourpetal Pawpaw is frost-tender (hardy to USDA zone 12). In colder areas grow it in a container and move it to a bright, frost-free place before the first frost.

Fourpetal Pawpaw can be propagated through seeds, suckers. Similar propagation techniques also apply to pawpaw plant care, which shares the same genus.
