What Soil Mix Works Best for a Lapland Rhododendron?

Well-draining, acidic soil with high organic matter content such as peat moss, pine bark, and perlite. Good drainage is essential for Lapland Rhododendron to prevent waterlogging, which leads to root rot and fungal issues.

How Often Should You Fertilize a Lapland Rhododendron?

Feed Lapland Rhododendron 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 Lapland Rhododendron?

Choose a spot with partial shade to full sun and well-draining, acidic soil with high organic matter content such as peat moss, pine bark, and perlite. Avoid low spots where water collects after rain.

Lapland Rhododendron is suited to USDA Zone 11a.

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 Lapland Rhododendron?

Lapland Rhododendron can spread to about 6 ft (1.8 m) and reach about 6 ft (2 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.

How Do You Prune a Lapland Rhododendron?

Prune Lapland Rhododendron 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.

Lapland Rhododendron is frost-tender (hardy to USDA zone 11). In colder areas grow it in a container and move it to a bright, frost-free place before the first frost.
