Wavy-leaved Agonis Plant Care

Wavy-leaved Agonis (Agonis undulata) belongs to the Myrtaceae family within the Agonis genus. Wavy-leaved Agonis is native to the Fitzgerald River National Park in the south of Western Australia.

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

Leaf size: approximately 3 inches.

Water a young or newly planted Wavy-leaved 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.

Wavy-leaved Agonis thrives in full sun to partial shade.

Agonis undulata tolerates temperatures of 50–85°F. Wavy-leaved Agonis prefers humidity levels of 40–70%.

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

Feed Wavy-leaved 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.

Wavy-leaved 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.

Wavy-leaved 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 Wavy-leaved 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.

Wavy-leaved 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.

Wavy-leaved 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.

Wavy-leaved 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.

Wavy-leaved Agonis grows outdoors in USDA Zone 12a. It survives winters down to planting zone 12a. Wavy-leaved Agonis is native to the Fitzgerald River National Park in the south of Western Australia. In cooler regions, grow Wavy-leaved Agonis as a houseplant or bring it indoors before the first frost.
