Azaleas do well in moist, acid (pH 5.5 or so), well-drained soil with lots of organic matter, such as peat, compost, chopped leaves, or ground bark. They won't grow in heavy clay, pure sand, or alkaline soil. If your existing soil is too bad to fix, plant azaleas in raised beds or containers.

Where do azaleas grow best?

Azaleas do well in full sun or part shade (about four hours of sun). Planted in full sun, azaleas will be more compact and floriferous. When planted in part shade, they will stretch toward the sunlight and form a more graceful habit; flowers will not be as plentiful but will last longer.

What helps azaleas grow?

Select a location that has morning sun and afternoon shade, or filtered light. Hot all-day sun can stress the plants and make them more susceptible to pests. Azaleas also require well-drained, acidic soil. Ideally, you would want to test the soil pH using a soil testing kit.
