June plum Plant Care

June plum (Spondias dulcis) belongs to the Anacardiaceae family within the Spondias genus. June plum is native to Melanesia, with edible fruit containing a fibrous pit. June plum is also known as Ambarella, Golden apple, Tahitian gooseberry.

June plum displays a medium-sized tree growth habit, reaching up to 30 ft tall with a spread of approximately 20 ft. June plum produces small, inconspicuous flowers in clusters.

Leaf size: approximately 6 inches.

Water a young or newly planted June plum 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.

June plum thrives in full sun to partial shade.

Spondias dulcis tolerates temperatures of 60–85°F. June plum 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 June plum to prevent waterlogging, which leads to root rot and fungal issues.

Feed June plum 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.

June plum 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.

June plum 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 June plum 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.

June plum 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.

June plum can be propagated through seeds, grafting. Similar propagation techniques also apply to yellow mombin plant care, which shares the same genus.

June plum is susceptible to fruit flies, caterpillars. Inspect the foliage regularly, especially along leaf undersides and stems. Treat infestations promptly with insecticidal soap or neem oil to prevent spread.

June plum grows outdoors in USDA Zone 13a. It survives winters down to planting zone 13a. June plum is native to Melanesia, with edible fruit containing a fibrous pit. In cooler regions, grow June plum as a houseplant or bring it indoors before the first frost.
