Mountain Fetterbush Plant Care

Mountain Fetterbush (Pieris floribunda) belongs to the Ericaceae family within the Pieris genus. Mountain Fetterbush is also known as Andromeda.

Mountain Fetterbush displays a compact, mounding shrub growth habit, reaching up to 6 ft tall with a spread of approximately 6 ft. Mountain Fetterbush produces clusters of small, urn-shaped white or pink flowers.

Leaf size: approximately 2 inches.

Water a young or newly planted Mountain Fetterbush 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.

Mountain Fetterbush thrives in partial shade to full shade. The optimal light range is 100–500 lux. Avoid placing Mountain Fetterbush in direct, harsh sunlight for extended periods, as this can scorch the foliage.

Pieris floribunda tolerates temperatures of 40–70°F. Mountain Fetterbush prefers humidity levels of 40–60%.

Well-draining acidic soil with high organic content, such as peat moss and pine bark. Good drainage is essential for Mountain Fetterbush to prevent waterlogging, which leads to root rot and fungal issues.

Feed Mountain 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.

Choose a spot with partial shade to full shade and well-draining acidic soil with high organic content, such as peat moss and pine bark. Avoid low spots where water collects after rain.

Mountain Fetterbush is suited to USDA Zone 11a.

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.

Mountain Fetterbush can spread to about 6 ft (1.8 m) and reach about 6 ft (2 m) tall. Space plants about 6 ft (1.8 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune Mountain 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.

Mountain Fetterbush is frost-tender (hardy to USDA zone 11). In colder areas grow it in a container and move it to a bright, frost-free place before the first frost.

Mountain Fetterbush can be propagated through softwood cuttings in early summer, layering. Similar propagation techniques also apply to formosan andromeda plant care, which shares the same genus.

Mountain Fetterbush is susceptible to aphids, lace bugs, nematodes. Inspect the foliage regularly, especially along leaf undersides and stems. Treat infestations promptly with insecticidal soap or neem oil to prevent spread.

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