Alsinidendron obovatum Plant Care

Alsinidendron obovatum (Alsinidendron obovatum) belongs to the Caryophyllaceae family within the Alsinidendron genus. Alsinidendron obovatum is native to the island of Oahu in the Hawaiian Islands.

Alsinidendron obovatum displays a compact, low-growing shrub growth habit, reaching up to 1.5 ft tall with a spread of approximately 1.5 ft. Alsinidendron obovatum produces small white or pink flowers in clusters.

Leaf size: approximately 2 inches.

Water a young or newly planted Alsinidendron obovatum every 7–10 days, soaking the whole root zone, until it is established — usually one to two growing seasons. Established shrubs mainly need water during long dry spells. In a container, water whenever the top few centimetres of soil are dry.

Alsinidendron obovatum thrives in bright indirect light. Avoid placing Alsinidendron obovatum in direct, harsh sunlight for extended periods, as this can scorch the foliage.

Alsinidendron obovatum tolerates temperatures of 65–75°F. Alsinidendron obovatum prefers humidity levels of 50–70%. A pebble tray or humidifier helps maintain adequate moisture around the plant.

Well-draining sandy soil mix with high organic content. Good drainage is essential for Alsinidendron obovatum to prevent waterlogging, which leads to root rot and fungal issues.

Feed Alsinidendron obovatum every 6 months during the growing season with a balanced, slow-release fertilizer at the rate on the label. Established shrubs 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 bright indirect light and well-draining sandy soil mix with high organic content. Avoid low spots where water collects after rain.

Alsinidendron obovatum is suited to USDA Zone 13b.

Plant container-grown or balled-and-burlapped shrubs in spring or early autumn, setting the root flare at soil level, and water well after planting.

Alsinidendron obovatum can spread to about 2 ft (0.5 m) and reach about 2 ft (0 m) tall. Space plants about 2 ft (0.5 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune Alsinidendron obovatum 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 shrub in one year.

Alsinidendron obovatum 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.

Alsinidendron obovatum can be propagated through seeds, stem cuttings.

Alsinidendron obovatum 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.

Alsinidendron obovatum grows outdoors in USDA Zone 13b. It survives winters down to planting zone 13b. Alsinidendron obovatum is native to the island of Oahu in the Hawaiian Islands. In cooler regions, grow Alsinidendron obovatum as a houseplant or bring it indoors before the first frost.
