Oppenheim's Prayer Plant Plant Care

Oppenheim's Prayer Plant (Ctenanthe oppenheimiana) belongs to the Marantaceae family within the Ctenanthe genus. Oppenheim's Prayer Plant is also known as Giant Prayer Plant.

Oppenheim's Prayer Plant displays a low rosette, clumping growth habit, reaching up to 2 ft tall with a spread of approximately 2 ft. Oppenheim's Prayer Plant produces small, insignificant flowers.

Leaf size: approximately 12 inches.

Water a young or newly planted Oppenheim's Prayer Plant 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.

Oppenheim's Prayer Plant thrives in bright indirect to medium light. Avoid placing Oppenheim's Prayer Plant in direct, harsh sunlight for extended periods, as this can scorch the foliage.

Ctenanthe oppenheimiana tolerates temperatures of 65–80°F. Oppenheim's Prayer Plant prefers humidity levels of 50–70%. A pebble tray or humidifier helps maintain adequate moisture around the plant.

Well-draining, peat-based potting mix with added perlite and sand. Good drainage is essential for Oppenheim's Prayer Plant to prevent waterlogging, which leads to root rot and fungal issues.

Feed Oppenheim's Prayer Plant 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 to medium light and well-draining, peat-based potting mix with added perlite and sand. Avoid low spots where water collects after rain.

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.

Oppenheim's Prayer Plant can spread to about 2 ft (0.6 m) and reach about 2 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 Oppenheim's Prayer Plant 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.

Oppenheim's Prayer Plant 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.

Oppenheim's Prayer Plant can be propagated through division, stem cuttings. Similar propagation techniques also apply to fishbone prayer plant plant care, which shares the same genus.
