Cassipourea subcordata Plant Care

Cassipourea subcordata (Cassipourea subcordata) belongs to the Rhizophoraceae family within the Cassipourea genus. Cassipourea subcordata is native to Jamaica.

Cassipourea subcordata displays a tall tree, spreading canopy growth habit, reaching up to 30 ft tall with a spread of approximately 20 ft. Cassipourea subcordata produces small clusters of white or yellow flowers.

Leaf size: approximately 6 inches.

Water a young or newly planted Cassipourea subcordata every 7–14 days, soaking the whole root zone, until it is established — usually one to two growing seasons. Established trees mainly need water during long dry spells. In a container, water whenever the top few centimetres of soil are dry.

Cassipourea subcordata thrives in partial to full sun.

Cassipourea subcordata tolerates temperatures of 65–85°F. Cassipourea subcordata prefers humidity levels of 50–80%. A pebble tray or humidifier helps maintain adequate moisture around the plant.

Well-draining sandy soil with high organic content. Good drainage is essential for Cassipourea subcordata to prevent waterlogging, which leads to root rot and fungal issues.

Feed Cassipourea subcordata every 6 months during the growing season with a balanced, slow-release fertilizer at the rate on the label. Established trees 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.

The PlantoScan app can remind you when to water and when to fertilize each plant.

Choose a spot with partial to full sun and well-draining sandy soil with high organic content. Avoid low spots where water collects after rain.

Cassipourea subcordata is suited to USDA Zone 13b.

Plant container-grown or balled-and-burlapped trees in spring or early autumn, setting the root flare at soil level, and water well after planting.

Cassipourea subcordata can spread to about 20 ft (6.1 m) and reach about 30 ft (9 m) tall. Space plants about 20 ft (6.1 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune Cassipourea subcordata 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 tree in one year.

Cassipourea subcordata 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.

Cassipourea subcordata can be propagated through seeds, stem cuttings. Similar propagation techniques also apply to cassipourea malosana plant care, which shares the same genus.

Cassipourea subcordata is susceptible to aphids, scale insects, spider mites. Inspect the foliage regularly, especially along leaf undersides and stems. Treat infestations promptly with insecticidal soap or neem oil to prevent spread.

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