Meriania ampla Plant Care

Meriania ampla (Meriania ampla) belongs to the Melastomataceae family within the Meriania genus. Meriania ampla is native to Ecuador.

Meriania ampla displays a compact shrub with dense foliage growth habit, reaching up to 3 ft tall with a spread of approximately 2 ft. Meriania ampla produces showy, colorful clusters of small flowers.

Leaf size: approximately 6 inches.

Water a young or newly planted Meriania ampla every 7–10 days, soaking the whole root zone, until it is established — usually one to two growing seasons. Established shrubs mainly need water during long dry spells. In a container, water whenever the top few centimetres of soil are dry.

Meriania ampla thrives in bright indirect light. Avoid placing Meriania ampla in direct, harsh sunlight for extended periods, as this can scorch the foliage.

Meriania ampla tolerates temperatures of 65–80°F. Meriania ampla prefers humidity levels of 50–70%. 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 Meriania ampla to prevent waterlogging, which leads to root rot and fungal issues.

Feed Meriania ampla every 6 months during the growing season with a balanced, slow-release fertilizer at the rate on the label. Established shrubs 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 bright indirect light and well-draining, acidic soil with high organic content. Avoid low spots where water collects after rain.

Meriania ampla is suited to USDA Zone 13b.

Plant container-grown or balled-and-burlapped shrubs in spring or early autumn, setting the root flare at soil level, and water well after planting.

Meriania ampla can spread to about 2 ft (0.6 m) and reach about 3 ft (1 m) tall. Space plants about 2 ft (0.6 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune Meriania ampla 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 shrub in one year.

Meriania ampla 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.

Meriania ampla can be propagated through softwood cuttings, air layering, division. Similar propagation techniques also apply to meriania acostae plant care, which shares the same genus.
