What Soil Mix Works Best for a Finger Aralia?

Loamy, well-draining soil mix with added peat moss and perlite. Good drainage is essential for Finger Aralia to prevent waterlogging, which leads to root rot and fungal issues.

How Often Should You Fertilize a Finger Aralia?

Feed Finger Aralia 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.

Where Should You Plant a Finger Aralia?

Choose a spot with bright indirect light and loamy, well-draining soil mix with added peat moss and perlite. Avoid low spots where water collects after rain.

Finger Aralia is suited to USDA Zone 13b.

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 Finger Aralia?

Finger Aralia can spread to about 5 ft (1.5 m) and reach about 10 ft (3 m) tall. Space plants about 5 ft (1.5 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

How Do You Prune a Finger Aralia?

Prune Finger Aralia while it is dormant in late winter: first remove dead, damaged and crossing branches, then thin lightly for shape.
