The plant we know as azalea is a rhododendron. The genetics and taxonomy of the azalea is as complex as the flower is beautiful. Azaleas are especially well adapted to the climatic conditions of southeastern North Carolina. Growing azaleas is easy if you follow a few basic steps. Choose a cool, partially shaded site for an azalea planting.
Many varieties can tolerate full sun if adequate soil moisture is maintained.
However, nearly all cultivars of azalea prefer an area that is not exposed to long periods of full hot sun. Plants grow best in a protected, acidic, well-drained soil with a pH of 5.5. Raised beds are essential for optimum azalea growth in most coastal plain soils. Elevate the plant bed 8 to 12 inches above grade to ensure good surface and internal drainage. Well-decayed pine bark, sawdust, or compost make a good organic amendment for azaleas.
