Saltbush Kunzea Plant Care

Saltbush Kunzea (Kunzea salterae) belongs to the Myrtaceae family within the Kunzea genus. Saltbush Kunzea is native to Moutohora Island in New Zealand. Saltbush Kunzea is also known as Salter's kunzea.

Saltbush Kunzea displays an upright, bushy shrub growth habit, reaching up to 4 ft tall with a spread of approximately 3 ft. Saltbush Kunzea produces small white or pink flowers in clusters.

Leaf size: approximately 2 inches.

Water a young or newly planted Saltbush Kunzea every 7–14 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.

Saltbush Kunzea thrives in full sun to partial shade.

Kunzea salterae tolerates temperatures of 50–80°F. Saltbush Kunzea prefers humidity levels of 40–70%.

Well-draining sandy soil mix with added organic matter like compost. Good drainage is essential for Saltbush Kunzea to prevent waterlogging, which leads to root rot and fungal issues.

Feed Saltbush Kunzea 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 well-draining sandy soil mix with added organic matter like compost. Avoid low spots where water collects after rain.

Saltbush Kunzea is suited to USDA Zone 9b – 11a.

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.

Saltbush Kunzea 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 Saltbush Kunzea 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.

Saltbush Kunzea is frost-tender (hardy to USDA zone 9). In colder areas grow it in a container and move it to a bright, frost-free place before the first frost.

Saltbush Kunzea can be propagated through softwood cuttings, seeds.

Saltbush Kunzea grows outdoors in USDA Zone 9b – 11a. It survives winters down to planting zone 9b. Saltbush Kunzea is native to Moutohora Island in New Zealand. In cooler regions, grow Saltbush Kunzea as a houseplant or bring it indoors before the first frost.
