Pachycentria glauca Plant Care

Pachycentria glauca (Pachycentria glauca) belongs to the Melastomataceae family within the Pachycentria genus. Pachycentria glauca is native to Peninsular Malaysia and Thailand, perhaps Sumatra.

Pachycentria glauca displays a compact, spreading shrub growth habit, reaching up to 2.5 ft tall with a spread of approximately 3 ft. Pachycentria glauca produces showy, bright pink flowers in clusters.

Leaf size: approximately 5 inches.

Water a young or newly planted Pachycentria glauca 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.

Pachycentria glauca thrives in filtered sunlight or partial shade. Avoid placing Pachycentria glauca in direct, harsh sunlight for extended periods, as this can scorch the foliage.

Pachycentria glauca tolerates temperatures of 60–75°F. Pachycentria glauca 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 Pachycentria glauca to prevent waterlogging, which leads to root rot and fungal issues.

Feed Pachycentria glauca 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 filtered sunlight or partial shade and well-draining, acidic soil with high organic content. Avoid low spots where water collects after rain.

Pachycentria glauca is suited to USDA Zone 13a.

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.

Pachycentria glauca can spread to about 3 ft (0.9 m) and reach about 3 ft (1 m) tall. Space plants about 3 ft (0.9 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune Pachycentria glauca 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.

Pachycentria glauca 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.

Pachycentria glauca can be propagated through stem cuttings, division, air layering.

Pachycentria glauca 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.

Pachycentria glauca grows outdoors in USDA Zone 13a. It survives winters down to planting zone 13a. Pachycentria glauca is native to Peninsular Malaysia and Thailand, perhaps Sumatra. In cooler regions, grow Pachycentria glauca as a houseplant or bring it indoors before the first frost.
