Kaala Casearia Plant Care

Kaala Casearia (Casearia kaalaensis) belongs to the Salicaceae family within the Casearia genus. Kaala Casearia is native to New Caledonia. Kaala Casearia is also known as Hawaiian false elder.

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

Leaf size: approximately 4 inches.

Water a young or newly planted Kaala Casearia 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.

Kaala Casearia thrives in partial to full sun.

Casearia kaalaensis tolerates temperatures of 60–85°F. Kaala Casearia prefers humidity levels of 50–80%. A pebble tray or humidifier helps maintain adequate moisture around the plant.

Well-draining loamy soil with added organic matter for moisture retention. Good drainage is essential for Kaala Casearia to prevent waterlogging, which leads to root rot and fungal issues.

Feed Kaala Casearia 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 loamy soil with added organic matter for moisture retention. Avoid low spots where water collects after rain.

Kaala Casearia is suited to USDA Zone 10b – 11b.

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.

Kaala Casearia 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 Kaala Casearia 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.

Kaala Casearia is frost-tender (hardy to USDA zone 10). In colder areas grow it in a container and move it to a bright, frost-free place before the first frost.

Kaala Casearia can be propagated through seeds, stem cuttings. Similar propagation techniques also apply to florida physic nut plant care, which shares the same genus.

Kaala Casearia 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.

Kaala Casearia grows outdoors in USDA Zone 10b – 11b. It survives winters down to planting zone 10b. Kaala Casearia is native to New Caledonia. In cooler regions, grow Kaala Casearia as a houseplant or bring it indoors before the first frost.
