Fetterbush Plant Care

Fetterbush (Lyonia octandra) belongs to the Ericaceae family within the Lyonia genus. Fetterbush is native to Jamaica. Fetterbush is also known as Maleberry.

Fetterbush displays an upright, dense shrub growth habit, reaching up to 6 ft tall with a spread of approximately 4 ft. Fetterbush produces small bell-shaped white or pink flowers in clusters.

Leaf size: approximately 3 inches.

Water a young or newly planted Fetterbush every 7–10 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.

Fetterbush thrives in partial shade to full sun.

Lyonia octandra tolerates temperatures of 60–80°F. Fetterbush prefers humidity levels of 40–70%.

Well-draining acidic soil mix with added organic matter like peat moss and pine bark. Good drainage is essential for Fetterbush to prevent waterlogging, which leads to root rot and fungal issues.

Feed Fetterbush 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 shade to full sun and well-draining acidic soil mix with added organic matter like peat moss and pine bark. Avoid low spots where water collects after rain.

Fetterbush is suited to USDA Zone 10a – 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.

Fetterbush can spread to about 4 ft (1.2 m) and reach about 6 ft (2 m) tall. Space plants about 4 ft (1.2 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune Fetterbush 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.

Fetterbush 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.

Fetterbush can be propagated through seeds, softwood cuttings. Similar propagation techniques also apply to lyonia plant care, which shares the same genus.

Fetterbush 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.

Fetterbush grows outdoors in USDA Zone 10a – 11b. It survives winters down to planting zone 10a. Fetterbush is native to Jamaica. In cooler regions, grow Fetterbush as a houseplant or bring it indoors before the first frost.
