Myrtle Tea Tree Plant Care

Myrtle Tea Tree (Leptospermum myrtifolium) belongs to the Myrtaceae family within the Leptospermum genus. Myrtle Tea Tree is native to south eastern Australia. Myrtle Tea Tree is also known as Myrtle-leaved Tea Tree.

Myrtle Tea Tree displays an upright, spreading shrub growth habit, reaching up to 6 ft tall with a spread of approximately 4 ft. Myrtle Tea Tree produces small, white, pink, or red flowers with prominent stamens.

Leaf size: approximately 2 inches.

Water a young or newly planted Myrtle Tea Tree 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.

Myrtle Tea Tree thrives in full sun to partial shade.

Leptospermum myrtifolium tolerates temperatures of 50–80°F. Myrtle Tea Tree prefers humidity levels of 40–70%.

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

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

Myrtle Tea Tree 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.

Myrtle Tea Tree 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 Myrtle Tea Tree 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.

Myrtle Tea Tree 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.

Myrtle Tea Tree can be propagated through seeds, semi-hardwood cuttings. Similar propagation techniques also apply to new zealand tea tree plant care, which shares the same genus.
