Scaphocalyx spathacea Plant Care

Scaphocalyx spathacea (Scaphocalyx spathacea) belongs to the Achariaceae family within the Scaphocalyx genus.

Scaphocalyx spathacea displays a compact, bushy shrub growth habit, reaching up to 2.5 ft tall with a spread of approximately 2.5 ft. Scaphocalyx spathacea produces small, inconspicuous flowers.

Leaf size: approximately 4 inches.

Water a young or newly planted Scaphocalyx spathacea 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.

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

Scaphocalyx spathacea tolerates temperatures of 65–80°F. Scaphocalyx spathacea prefers humidity levels of 50–70%. A pebble tray or humidifier helps maintain adequate moisture around the plant.

Well-draining, rich potting mix with added perlite for aeration. Good drainage is essential for Scaphocalyx spathacea to prevent waterlogging, which leads to root rot and fungal issues.

Feed Scaphocalyx spathacea 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, rich potting mix with added perlite for aeration. Avoid low spots where water collects after rain.

Scaphocalyx spathacea 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.

Scaphocalyx spathacea can spread to about 3 ft (0.8 m) and reach about 3 ft (1 m) tall. Space plants about 3 ft (0.8 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune Scaphocalyx spathacea 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.

Scaphocalyx spathacea 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.

Scaphocalyx spathacea can be propagated through seeds, stem cuttings.

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