What Soil Mix Works Best for a Evergreen Azalea?
Well-draining acidic soil with high organic matter content, such as peat moss or pine bark. Good drainage is essential for Evergreen Azalea to prevent waterlogging, which leads to root rot and fungal issues.
How Often Should You Fertilize a Evergreen Azalea?
Feed Evergreen Azalea 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 Evergreen Azalea?
Choose a spot with filtered sunlight or partial shade and well-draining acidic soil with high organic matter content, such as peat moss or pine bark. Avoid low spots where water collects after rain.
Evergreen Azalea is suited to USDA Zone 8a – 9b.
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 Evergreen Azalea?
Evergreen Azalea can spread to about 5 ft (1.5 m) and reach about 5 ft (2 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 Evergreen Azalea?
Prune Evergreen Azalea 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.
How Do You Care for a Evergreen Azalea in Winter?
Evergreen Azalea is hardy down to USDA zone 8a, so once established it can stay outdoors through winter in that zone and warmer ones.
Water deeply in late autumn before the ground freezes, and spread a 5–8 cm (2–3 in) layer of mulch over the root zone, keeping it away from the trunk.
Young and container-grown trees need extra protection: roots in a pot freeze much more easily than roots in the ground.
How Do You Propagate a Evergreen Azalea?
Evergreen Azalea can be propagated through softwood cuttings, layering, seeds.
