Melicope wawraeana Plant Care

Melicope wawraeana (Melicope wawraeana) belongs to the Rutaceae family within the Melicope genus. Melicope wawraeana is native to the Hawaiian Islands.

Melicope wawraeana displays a small tree or shrub growth habit, reaching up to 10 ft tall with a spread of approximately 8 ft. Melicope wawraeana produces small, fragrant white flowers in clusters.

Leaf size: approximately 4 inches.

Water a young or newly planted Melicope wawraeana 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.

Melicope wawraeana thrives in full sun to partial shade.

Melicope wawraeana tolerates temperatures of 60–85°F. Melicope wawraeana 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. Good drainage is essential for Melicope wawraeana to prevent waterlogging, which leads to root rot and fungal issues.

Feed Melicope wawraeana 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. Avoid low spots where water collects after rain.

Melicope wawraeana 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.

Melicope wawraeana can spread to about 8 ft (2.4 m) and reach about 10 ft (3 m) tall. Space plants about 8 ft (2.4 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune Melicope wawraeana 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.

Melicope wawraeana 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.

Melicope wawraeana can be propagated through seeds, stem cuttings. Similar propagation techniques also apply to melicope accedens plant care, which shares the same genus.

Melicope wawraeana is susceptible to citrus leafminer, scale insects, citrus psyllid. Inspect the foliage regularly, especially along leaf undersides and stems. Treat infestations promptly with insecticidal soap or neem oil to prevent spread.

Melicope wawraeana grows outdoors in USDA Zone 13a. It survives winters down to planting zone 13a. Melicope wawraeana is native to the Hawaiian Islands. In cooler regions, grow Melicope wawraeana as a houseplant or bring it indoors before the first frost.
