Aspiromitus havaiensis Plant Care

Aspiromitus havaiensis (Aspiromitus havaiensis) belongs to the Anthocerotaceae family within the Aspiromitus genus.

Aspiromitus havaiensis displays a low rosette, spreading growth habit, reaching up to 0.5 ft tall with a spread of approximately 1 ft. Aspiromitus havaiensis produces small, inconspicuous greenish flowers.

Leaf size: approximately 3 inches.

Water a young or newly planted Aspiromitus havaiensis 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.

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

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

Well-draining peat-based mix with perlite and orchid bark. Good drainage is essential for Aspiromitus havaiensis to prevent waterlogging, which leads to root rot and fungal issues.

Feed Aspiromitus havaiensis 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 peat-based mix with perlite and orchid bark. Avoid low spots where water collects after rain.

Aspiromitus havaiensis 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.

Aspiromitus havaiensis 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 Aspiromitus havaiensis 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.

Aspiromitus havaiensis 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.

Aspiromitus havaiensis can be propagated through spores, division of rhizomes.

Aspiromitus havaiensis is susceptible to fungus gnats, 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.

Aspiromitus havaiensis grows outdoors in USDA Zone 13a. It survives winters down to planting zone 13a. In cooler regions, grow Aspiromitus havaiensis as a houseplant or bring it indoors before the first frost.
