Cuban Hernandia Plant Care

Cuban Hernandia (Hernandia cubensis) belongs to the Hernandiaceae family within the Hernandia genus. Cuban Hernandia is native to Cuba.

Cuban Hernandia displays a small to medium-sized tree growth habit, reaching up to 20 ft tall with a spread of approximately 15 ft. Cuban Hernandia produces small, inconspicuous flowers.

Leaf size: approximately 6 inches.

Water a young or newly planted Cuban Hernandia 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 Hernandia thrives in partial shade to full sun.

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

Well-draining loamy soil with added organic matter for moisture retention. Good drainage is essential for Cuban Hernandia to prevent waterlogging, which leads to root rot and fungal issues.

Feed Cuban Hernandia 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 partial shade to full sun and well-draining loamy soil with added organic matter for moisture retention. Avoid low spots where water collects after rain.

Cuban Hernandia is suited to USDA Zone 10b – 12b.

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 Hernandia can spread to about 15 ft (4.6 m) and reach about 20 ft (6 m) tall. Space plants about 15 ft (4.6 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune Cuban Hernandia 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 Hernandia is frost-tender (hardy to USDA zone 10). In colder areas grow it in a container and move it to a bright, frost-free place before the first frost.

Cuban Hernandia can be propagated through seeds, stem cuttings. Similar propagation techniques also apply to hernandia plant care, which shares the same genus.

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

Cuban Hernandia grows outdoors in USDA Zone 10b – 12b. It survives winters down to planting zone 10b. Cuban Hernandia is native to Cuba. In cooler regions, grow Cuban Hernandia as a houseplant or bring it indoors before the first frost.
