Wilkiea hylandii Plant Care

Wilkiea hylandii (Wilkiea hylandii) belongs to the Monimiaceae family within the Wilkiea genus. Wilkiea hylandii is native to Cape York Peninsula in far northern Queensland.

Wilkiea hylandii displays a small tree, shrub growth habit, reaching up to 10 ft tall with a spread of approximately 6 ft. Wilkiea hylandii produces small, inconspicuous flowers.

Leaf size: approximately 4 inches.

Water a young or newly planted Wilkiea hylandii every 7–10 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.

Wilkiea hylandii thrives in partial shade to full shade. The optimal light range is 100–500 lux. Avoid placing Wilkiea hylandii in direct, harsh sunlight for extended periods, as this can scorch the foliage.

Wilkiea hylandii tolerates temperatures of 60–75°F. Wilkiea hylandii prefers humidity levels of 50–70%. A pebble tray or humidifier helps maintain adequate moisture around the plant.

Well-draining, slightly acidic soil with high organic matter content. Good drainage is essential for Wilkiea hylandii to prevent waterlogging, which leads to root rot and fungal issues.

Feed Wilkiea hylandii 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 partial shade to full shade and well-draining, slightly acidic soil with high organic matter content. Avoid low spots where water collects after rain.

Wilkiea hylandii 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.

Wilkiea hylandii can spread to about 6 ft (1.8 m) and reach about 10 ft (3 m) tall. Space plants about 6 ft (1.8 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune Wilkiea hylandii 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.

Wilkiea hylandii 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.

Wilkiea hylandii can be propagated through seeds, stem cuttings. Similar propagation techniques also apply to wilkiea angustifolia plant care, which shares the same genus.

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

Wilkiea hylandii grows outdoors in USDA Zone 13a. It survives winters down to planting zone 13a. Wilkiea hylandii is native to Cape York Peninsula in far northern Queensland. In cooler regions, grow Wilkiea hylandii as a houseplant or bring it indoors before the first frost.
