Hasseltia dioica Plant Care

Hasseltia dioica (Hasseltiopsis dioica) belongs to the Salicaceae family within the Hasseltiopsis genus. Hasseltia dioica is native to southern Mexico and Costa Rica.

Hasseltia dioica displays a fast-growing shrub growth habit, reaching up to 4 ft tall with a spread of approximately 3 ft. Hasseltia dioica produces small, inconspicuous flowers in clusters.

Leaf size: approximately 4 inches.

Water a young or newly planted Hasseltia dioica every 4–7 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.

Hasseltia dioica thrives in full sun to partial shade.

Hasseltiopsis dioica tolerates temperatures of 60–85°F. Hasseltia dioica prefers humidity levels of 40–70%.

Moist, well-draining soil rich in organic matter. Good drainage is essential for Hasseltia dioica to prevent waterlogging, which leads to root rot and fungal issues.

Feed Hasseltia dioica 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 full sun to partial shade and moist, well-draining soil rich in organic matter. Avoid low spots where water collects after rain.

Hasseltia dioica is suited to USDA Zone 10b – 12b.

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.

Hasseltia dioica can spread to about 3 ft (0.9 m) and reach about 4 ft (1 m) tall. Space plants about 3 ft (0.9 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune Hasseltia dioica 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.

Hasseltia dioica 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.

Hasseltia dioica can be propagated through seed, softwood cuttings.

Hasseltia dioica 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.

Hasseltia dioica grows outdoors in USDA Zone 10b – 12b. It survives winters down to planting zone 10b. Hasseltia dioica is native to southern Mexico and Costa Rica. In cooler regions, grow Hasseltia dioica as a houseplant or bring it indoors before the first frost.
