Callicladium haldanianum Plant Care

Callicladium haldanianum (Callicladium haldanianum) belongs to the Pylaisiaceae family within the Callicladium genus. Callicladium haldanianum is native to North America.

Callicladium haldanianum displays a low rosette, spreading growth habit, reaching up to 0.5 ft tall with a spread of approximately 1 ft. Callicladium haldanianum produces tiny inconspicuous flowers.

Leaf size: approximately 2 inches.

Water a young or newly planted Callicladium haldanianum 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.

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

Callicladium haldanianum tolerates temperatures of 60–75°F. Callicladium haldanianum prefers humidity levels of 50–70%. A pebble tray or humidifier helps maintain adequate moisture around the plant.

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

Feed Callicladium haldanianum 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, acidic soil mix with high organic content. Avoid low spots where water collects after rain.

Callicladium haldanianum is suited to USDA Zone 13a.

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.

Callicladium haldanianum can spread to about 1 ft (0.3 m) and reach about 1 ft (0 m) tall. Space plants about 1 ft (0.3 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune Callicladium haldanianum 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.

Callicladium haldanianum 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.

Callicladium haldanianum can be propagated through division, spores.

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