What Potting Soil Do I Use for Azaleas?

Updated November 21, 2016

Azaleas are members of the Heath family of plants and are both of the species and genus Rhododendron. They come in many varieties, but all have the same basic needs -- plenty of well-drained, low-pH potting or treated soil.

Geography

Azaleas grow in most of the United States. The largest variety grows in the southeastern part of the country, however.

Soil

Azaleas need a low-pH type of soil. If possible, buy potting soil made just for azaleas. If that is not possible, mix milled sphagnum peat moss with your regular potting soil.

Considerations

Soil must be pH 4.5 to 5.5 and well-drained. Azaleas do not like to stand in water.

Planting

Azaleas are considered perennials, so will do well in the garden if the soil conditions are right. A large hole filled with potting soil made for azaleas will provide what they need.

Summation

Azaleas are fairly shallow-rooted, so potting soil with a low pH works well either in the garden or in containers. Keep them moist, but not wet, and they should do well for you.
