Weeping Lilly Pilly Plant Care

Weeping Lilly Pilly (Syzygium fibrosum) belongs to the Myrtaceae family within the Syzygium genus. Weeping Lilly Pilly is native to rainforest, monsoon forest and gallery forest of New Guinea, and northern Australia. Weeping Lilly Pilly is also known as Weeping Myrtus.

Weeping Lilly Pilly displays a tall, dense tree or shrub growth habit, reaching up to 20 ft tall with a spread of approximately 15 ft. Weeping Lilly Pilly produces small, white, fluffy flowers in clusters.

Leaf size: approximately 4 inches.

Water a young or newly planted Weeping Lilly Pilly 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.

Weeping Lilly Pilly thrives in full sun to partial shade.

Syzygium fibrosum tolerates temperatures of 60–85°F. Weeping Lilly Pilly prefers humidity levels of 50–80%. A pebble tray or humidifier helps maintain adequate moisture around the plant.

Well-draining, slightly acidic soil with added organic matter like compost or peat moss. Good drainage is essential for Weeping Lilly Pilly to prevent waterlogging, which leads to root rot and fungal issues.

Feed Weeping Lilly Pilly 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, slightly acidic soil with added organic matter like compost or peat moss. Avoid low spots where water collects after rain.

Weeping Lilly Pilly is suited to USDA Zone 13a.

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.

Weeping Lilly Pilly can spread to about 15 ft (4.6 m) and reach about 20 ft (6 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 Weeping Lilly Pilly 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.

Weeping Lilly Pilly is frost-tender (hardy to USDA zone 13). In colder areas grow it in a container and move it to a bright, frost-free place before the first frost.

Weeping Lilly Pilly can be propagated through seeds, semi-hardwood cuttings. Similar propagation techniques also apply to waterberry plant care, which shares the same genus.
