White Peppermint Plant Care

White Peppermint (Eucalyptus pulchella) belongs to the Myrtaceae family within the Eucalyptus genus. White Peppermint is native to Tasmania. White Peppermint is also known as Peppermint Gum, Narrow-leaved Peppermint.

White Peppermint displays a fast-growing tall tree growth habit, reaching up to 100 ft tall with a spread of approximately 50 ft. White Peppermint produces small white, cream, or pink flowers in clusters.

Leaf size: approximately 6 inches.

Water a young or newly planted White Peppermint 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.

White Peppermint thrives in full sun.

Eucalyptus pulchella tolerates temperatures of 50–85°F. White Peppermint prefers humidity levels of 40–70%.

Well-draining sandy loam with some organic matter. Good drainage is essential for White Peppermint to prevent waterlogging, which leads to root rot and fungal issues.

Feed White Peppermint 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 full sun and well-draining sandy loam with some organic matter. Avoid low spots where water collects after rain.

White Peppermint is suited to USDA Zone 12a.

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.

White Peppermint can spread to about 50 ft (15.2 m) and reach about 100 ft (30 m) tall. Space plants about 50 ft (15.2 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune White Peppermint 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.

White Peppermint is frost-tender (hardy to USDA zone 12). In colder areas grow it in a container and move it to a bright, frost-free place before the first frost.

White Peppermint can be propagated through seeds, cuttings. Similar propagation techniques also apply to silver dollar eucalyptus plant care, which shares the same genus.

White Peppermint is susceptible to lerp psyllids, eucalyptus gall wasp. Inspect the foliage regularly, especially along leaf undersides and stems. Treat infestations promptly with insecticidal soap or neem oil to prevent spread.

White Peppermint grows outdoors in USDA Zone 12a. It survives winters down to planting zone 12a. White Peppermint is native to Tasmania. In cooler regions, grow White Peppermint as a houseplant or bring it indoors before the first frost.
