Caldcluvia paniculata Plant Care

Caldcluvia paniculata (Caldcluvia paniculata) belongs to the Cunoniaceae family within the Caldcluvia genus. Caldcluvia paniculata is native to Chile.

Caldcluvia paniculata displays a tall, upright tree growth habit, reaching up to 30 ft tall with a spread of approximately 15 ft. Caldcluvia paniculata produces small clusters of white or pink flowers.

Leaf size: approximately 6 inches.

Water a young or newly planted Caldcluvia paniculata 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.

Caldcluvia paniculata thrives in partial to full sun.

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

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

Caldcluvia paniculata is suited to USDA Zone 8b – 10b.

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.

Caldcluvia paniculata can spread to about 15 ft (4.6 m) and reach about 30 ft (9 m) tall. Space plants about 15 ft (4.6 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune Caldcluvia paniculata 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.

Caldcluvia paniculata is hardy down to USDA zone 8b, so once established it can stay outdoors through winter in that zone and warmer ones.

Water deeply in late autumn before the ground freezes, and spread a 5–8 cm (2–3 in) layer of mulch over the root zone, keeping it away from the trunk.

Young and container-grown trees need extra protection: roots in a pot freeze much more easily than roots in the ground.

Caldcluvia paniculata can be propagated through seeds, cuttings.

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

Caldcluvia paniculata grows outdoors in USDA Zone 8b – 10b. It survives winters down to planting zone 8b. Caldcluvia paniculata is native to Chile.
