Arguacoensian star apple Plant Care

Arguacoensian star apple (Pouteria arguacoensium) belongs to the Sapotaceae family within the Pouteria genus. Arguacoensian star apple is native to the Sierra Nevada de Santa Marta in northeastern Colombia.

Arguacoensian star apple displays a tall, evergreen tree growth habit, reaching up to 30 ft tall with a spread of approximately 15 ft. Arguacoensian star apple produces small, inconspicuous flowers.

Leaf size: approximately 6 inches.

Water a young or newly planted Arguacoensian star apple 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.

Arguacoensian star apple thrives in full sun to partial shade.

Pouteria arguacoensium tolerates temperatures of 60–85°F. Arguacoensian star apple prefers humidity levels of 50–80%. A pebble tray or humidifier helps maintain adequate moisture around the plant.

Well-draining, rich loamy soil with added organic matter for moisture retention. Good drainage is essential for Arguacoensian star apple to prevent waterlogging, which leads to root rot and fungal issues.

Feed Arguacoensian star apple 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, rich loamy soil with added organic matter for moisture retention. Avoid low spots where water collects after rain.

Arguacoensian star apple 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.

Arguacoensian star apple can spread to about 15 ft (4.6 m) and reach about 30 ft (9 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 Arguacoensian star apple 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.

Arguacoensian star apple 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.

Arguacoensian star apple can be propagated through seeds, air-layering, grafting. Similar propagation techniques also apply to mamey sapote plant care, which shares the same genus.
