Assyrian Prune Plant Care

Assyrian Prune (Grewia damine) belongs to the Malvaceae family within the Grewia genus. Assyrian Prune is native to monsoon and intermediate forest gaps and fringes of Sri Lanka. Assyrian Prune is also known as False Apple.

Assyrian Prune displays an upright, spreading shrub growth habit, reaching up to 6 ft tall with a spread of approximately 4 ft. Assyrian Prune produces small, bell-shaped flowers in various colors.

Leaf size: approximately 3 inches.

Water a young or newly planted Assyrian Prune 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.

Assyrian Prune thrives in full sun to partial shade.

Grewia damine tolerates temperatures of 60–85°F. Assyrian Prune prefers humidity levels of 40–70%.

Well-draining sandy loam with added organic matter. Good drainage is essential for Assyrian Prune to prevent waterlogging, which leads to root rot and fungal issues.

Feed Assyrian Prune 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 sandy loam with added organic matter. Avoid low spots where water collects after rain.

Assyrian Prune 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.

Assyrian Prune can spread to about 4 ft (1.2 m) and reach about 6 ft (2 m) tall. Space plants about 4 ft (1.2 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune Assyrian Prune 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.

Assyrian Prune 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.

Assyrian Prune can be propagated through seeds, hardwood cuttings. Similar propagation techniques also apply to velvet grewia plant care, which shares the same genus.

Assyrian Prune is susceptible to aphids, scale insects, spider mites. Inspect the foliage regularly, especially along leaf undersides and stems. Treat infestations promptly with insecticidal soap or neem oil to prevent spread.

Assyrian Prune grows outdoors in USDA Zone 13a. It survives winters down to planting zone 13a. Assyrian Prune is native to monsoon and intermediate forest gaps and fringes of Sri Lanka. In cooler regions, grow Assyrian Prune as a houseplant or bring it indoors before the first frost.
