Where Should You Plant a Melicope degeneri?
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 degeneri 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.
How Far Apart Should You Plant a Melicope degeneri?
Melicope degeneri 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.
