White Tibouchina Plant Care

White Tibouchina (Tibouchina albescens) belongs to the Melastomataceae family within the Tibouchina genus. White Tibouchina is native to Bolivia and Brazil.

White Tibouchina displays an upright, bushy shrub growth habit, reaching up to 6 ft tall with a spread of approximately 4 ft. White Tibouchina produces showy, vibrant purple flowers.

Leaf size: approximately 4 inches.

Water a young or newly planted White Tibouchina every 7–10 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.

White Tibouchina thrives in full sun to partial shade.

Tibouchina albescens tolerates temperatures of 60–80°F. White Tibouchina 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 matter content. Good drainage is essential for White Tibouchina to prevent waterlogging, which leads to root rot and fungal issues.

Feed White Tibouchina 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, acidic soil with high organic matter content. Avoid low spots where water collects after rain.

White Tibouchina 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.

White Tibouchina 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 White Tibouchina 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.

White Tibouchina 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.

White Tibouchina can be propagated through softwood cuttings, seeds. Similar propagation techniques also apply to andean princess flower plant care, which shares the same genus.

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

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