Cuban False Heather Plant Care

Cuban False Heather (Mosiera havanensis) belongs to the Myrtaceae family within the Mosiera genus. Cuban False Heather is native to Cuba. Cuban False Heather is also known as Cuphea havanensis.

Cuban False Heather displays a tall, columnar tree growth habit, reaching up to 20 ft tall with a spread of approximately 10 ft. Cuban False Heather produces showy clusters of white or pink flowers.

Leaf size: approximately 6 inches.

Water a young or newly planted Cuban False Heather 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.

Cuban False Heather thrives in full sun to partial shade.

Mosiera havanensis tolerates temperatures of 65–80°F. Cuban False Heather prefers humidity levels of 50–70%. A pebble tray or humidifier helps maintain adequate moisture around the plant.

Well-draining acidic soil mix with peat moss and pine bark. Good drainage is essential for Cuban False Heather to prevent waterlogging, which leads to root rot and fungal issues.

Feed Cuban False Heather 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.

Choose a spot with full sun to partial shade and well-draining acidic soil mix with peat moss and pine bark. Avoid low spots where water collects after rain.

Cuban False Heather is suited to USDA Zone 13b – 11b.

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.

Cuban False Heather can spread to about 10 ft (3 m) and reach about 20 ft (6 m) tall. Space plants about 10 ft (3 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune Cuban False Heather 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.

Cuban False Heather 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.

Cuban False Heather can be propagated through softwood cuttings, air layering, seeds. Similar propagation techniques also apply to mosiera longipes plant care, which shares the same genus.

Cuban False Heather 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.
