Heartleaf Spathicarpa Plant Care

Heartleaf Spathicarpa (Spathicarpa hastifolia) belongs to the Araceae family within the Spathicarpa genus. Heartleaf Spathicarpa is native to South America.

Heartleaf Spathicarpa displays a clumping, low rosette growth habit, reaching up to 1.5 ft tall with a spread of approximately 1.5 ft. Heartleaf Spathicarpa produces small, inconspicuous flowers surrounded by a large, showy spathe.

Leaf size: approximately 12 inches.

Water a young or newly planted Heartleaf Spathicarpa 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.

Heartleaf Spathicarpa thrives in bright indirect to low light. Avoid placing Heartleaf Spathicarpa in direct, harsh sunlight for extended periods, as this can scorch the foliage.

Spathicarpa hastifolia tolerates temperatures of 65–80°F. Heartleaf Spathicarpa 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 Heartleaf Spathicarpa to prevent waterlogging, which leads to root rot and fungal issues.

Feed Heartleaf Spathicarpa 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 low light and well-draining, rich potting mix with added perlite for aeration. Avoid low spots where water collects after rain.

Heartleaf Spathicarpa 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.

Heartleaf Spathicarpa can spread to about 2 ft (0.5 m) and reach about 2 ft (0 m) tall. Space plants about 2 ft (0.5 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune Heartleaf Spathicarpa 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.

Heartleaf Spathicarpa 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.

Heartleaf Spathicarpa can be propagated through division of rhizomes, offsets, or seeds.
