Cyathocalyx zeylanicus Plant Care

Cyathocalyx zeylanicus (Cyathocalyx zeylanicus) belongs to the Annonaceae family within the Cyathocalyx genus. Cyathocalyx zeylanicus is native to the Western Ghats (India) and Sri Lanka.

Cyathocalyx zeylanicus displays a compact, bushy shrub growth habit, reaching up to 3 ft tall with a spread of approximately 2 ft. Cyathocalyx zeylanicus produces small, fragrant flowers in shades of white, pink, or purple.

Leaf size: approximately 6 inches.

Water a young or newly planted Cyathocalyx zeylanicus 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.

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

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

Well-draining, rich loamy soil with added organic matter. Good drainage is essential for Cyathocalyx zeylanicus to prevent waterlogging, which leads to root rot and fungal issues.

Feed Cyathocalyx zeylanicus 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 loamy soil with added organic matter. Avoid low spots where water collects after rain.

Cyathocalyx zeylanicus 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.

Cyathocalyx zeylanicus can spread to about 2 ft (0.6 m) and reach about 3 ft (1 m) tall. Space plants about 2 ft (0.6 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune Cyathocalyx zeylanicus 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.

Cyathocalyx zeylanicus 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.

Cyathocalyx zeylanicus can be propagated through seeds, stem cuttings.
