Tibouchina campii Plant Care

Tibouchina campii (Tibouchina campii) belongs to the Melastomataceae family within the Tibouchina genus. Tibouchina campii is native to Ecuador.

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

Leaf size: approximately 4 inches.

Water a young or newly planted Tibouchina campii 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.

Tibouchina campii thrives in full sun to partial shade.

Tibouchina campii tolerates temperatures of 60–80°F. Tibouchina campii 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 Tibouchina campii to prevent waterlogging, which leads to root rot and fungal issues.

Feed Tibouchina campii 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.

The PlantoScan app can remind you when to water and when to fertilize each plant.

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.

Tibouchina campii 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.

Tibouchina campii 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 Tibouchina campii 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.

Tibouchina campii 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.

Tibouchina campii can be propagated through softwood cuttings, seeds. Similar propagation techniques also apply to white tibouchina plant care, which shares the same genus.

Tibouchina campii 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.

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