Silky Tea Tree Plant Care

Silky Tea Tree (Leptospermum sericatum) belongs to the Myrtaceae family within the Leptospermum genus. Silky Tea Tree is native to Queensland.

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

Leaf size: approximately 2 inches.

Water a young or newly planted Silky 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.

Silky Tea Tree thrives in full sun to partial shade.

Leptospermum sericatum tolerates temperatures of 50–80°F. Silky 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 Silky Tea Tree to prevent waterlogging, which leads to root rot and fungal issues.

Feed Silky 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.

The PlantoScan app can remind you when to water and when to fertilize each plant.

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.

Silky 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.

Silky 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 Silky 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.

Silky 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.

Silky 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.

Silky Tea Tree is susceptible to aphids, scale insects, caterpillars. Inspect the foliage regularly, especially along leaf undersides and stems. Treat infestations promptly with insecticidal soap or neem oil to prevent spread.

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