Tea-flowered Agonis Plant Care

Tea-flowered Agonis (Agonis theiformis) belongs to the Myrtaceae family within the Agonis genus. Tea-flowered Agonis is native to the southwest of Western Australia.

Tea-flowered Agonis displays an upright, columnar tree growth habit, reaching up to 30 ft tall with a spread of approximately 15 ft. Tea-flowered Agonis produces small white flowers in clusters.

Leaf size: approximately 3 inches.

Water a young or newly planted Tea-flowered Agonis 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.

Tea-flowered Agonis thrives in full sun to partial shade.

Agonis theiformis tolerates temperatures of 50–85°F. Tea-flowered Agonis prefers humidity levels of 40–70%.

Well-draining sandy loam with added organic matter for moisture retention. Good drainage is essential for Tea-flowered Agonis to prevent waterlogging, which leads to root rot and fungal issues.

Feed Tea-flowered Agonis 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 sandy loam with added organic matter for moisture retention. Avoid low spots where water collects after rain.

Tea-flowered Agonis 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.

Tea-flowered Agonis can spread to about 15 ft (4.6 m) and reach about 30 ft (9 m) tall. Space plants about 15 ft (4.6 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune Tea-flowered Agonis 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.

Tea-flowered Agonis 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.

Tea-flowered Agonis can be propagated through seeds, semi-hardwood cuttings. Similar propagation techniques also apply to baxter's agonis plant care, which shares the same genus.

Tea-flowered Agonis 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.

Tea-flowered Agonis grows outdoors in USDA Zone 12a. It survives winters down to planting zone 12a. Tea-flowered Agonis is native to the southwest of Western Australia. In cooler regions, grow Tea-flowered Agonis as a houseplant or bring it indoors before the first frost.
