Carallia calycina Plant Care

Carallia calycina (Carallia calycina) belongs to the Rhizophoraceae family within the Carallia genus. Carallia calycina is native to Sri Lanka.

Carallia calycina displays a small to medium-sized tree growth habit, reaching up to 15 ft tall with a spread of approximately 10 ft. Carallia calycina produces small, inconspicuous flowers.

Leaf size: approximately 6 inches.

Water a young or newly planted Carallia calycina 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.

Carallia calycina thrives in partial to full sun.

Carallia calycina tolerates temperatures of 65–85°F. Carallia calycina prefers humidity levels of 50–80%. A pebble tray or humidifier helps maintain adequate moisture around the plant.

Rich, well-draining soil with high organic content. Good drainage is essential for Carallia calycina to prevent waterlogging, which leads to root rot and fungal issues.

Feed Carallia calycina 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 rich, well-draining soil with high organic content. Avoid low spots where water collects after rain.

Carallia calycina is suited to USDA Zone 13b.

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.

Carallia calycina can spread to about 10 ft (3 m) and reach about 15 ft (5 m) tall. Space plants about 10 ft (3 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune Carallia calycina 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.

Carallia calycina 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.

Carallia calycina can be propagated through seeds, stem cuttings. Similar propagation techniques also apply to carallia borneensis plant care, which shares the same genus.

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

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