Mouriri Plant Care

Mouriri (Mouriri guianensis) belongs to the Melastomataceae family within the Mouriri genus. Mouriri is native to South America.

Mouriri displays a small tree or shrub growth habit, reaching up to 6 ft tall with a spread of approximately 4 ft. Mouriri produces small, delicate pink or white flowers.

Leaf size: approximately 4 inches.

Water a young or newly planted Mouriri 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.

Mouriri thrives in partial shade to full sun.

Mouriri guianensis tolerates temperatures of 60–85°F. Mouriri prefers humidity levels of 50–80%. A pebble tray or humidifier helps maintain adequate moisture around the plant.

Well-draining acidic soil with high organic content. Good drainage is essential for Mouriri to prevent waterlogging, which leads to root rot and fungal issues.

Feed Mouriri 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 partial shade to full sun and well-draining acidic soil with high organic content. Avoid low spots where water collects after rain.

Mouriri 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.

Mouriri 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 Mouriri 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.

Mouriri 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.

Mouriri can be propagated through seeds, stem cuttings. Similar propagation techniques also apply to mouriri completens plant care, which shares the same genus.

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

Mouriri grows outdoors in USDA Zone 13a. It survives winters down to planting zone 13a. Mouriri is native to South America. In cooler regions, grow Mouriri as a houseplant or bring it indoors before the first frost.
