Mountain Allspice Plant Care

Mountain Allspice (Pimenta cainitoides) belongs to the Myrtaceae family within the Pimenta genus. Mountain Allspice is native to Cuba. Mountain Allspice is also known as Wild Cinnamon.

Mountain Allspice displays a small to medium-sized tree growth habit, reaching up to 15 ft tall with a spread of approximately 10 ft. Mountain Allspice produces small white flowers in clusters.

Leaf size: approximately 4 inches.

Water a young or newly planted Mountain Allspice 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.

Mountain Allspice thrives in full sun to partial shade.

Pimenta cainitoides tolerates temperatures of 60–85°F. Mountain Allspice prefers humidity levels of 50–70%. A pebble tray or humidifier helps maintain adequate moisture around the plant.

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

Feed Mountain Allspice 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 organic matter for moisture retention. Avoid low spots where water collects after rain.

Mountain Allspice is suited to USDA Zone 10b – 12b.

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.

Mountain Allspice 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 Mountain Allspice 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.

Mountain Allspice is frost-tender (hardy to USDA zone 10). In colder areas grow it in a container and move it to a bright, frost-free place before the first frost.

Mountain Allspice can be propagated through seeds, stem cuttings. Similar propagation techniques also apply to allspice tree plant care, which shares the same genus.

Mountain Allspice 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.

Mountain Allspice grows outdoors in USDA Zone 10b – 12b. It survives winters down to planting zone 10b. Mountain Allspice is native to Cuba. In cooler regions, grow Mountain Allspice as a houseplant or bring it indoors before the first frost.
