Azaleas, like most shrubs and trees, can be planted in spring or fall. Fall is preferred because the dormant season gives roots time to grow. Summertime heat and drought can cause stress. If you plant azaleas in the spring, be sure to mulch well and water throughout the summer.

Plant them in dense shade and they won't bloom. A good location is where they receive either dappled sun all day or sun in the morning and light shade in the afternoon. Good places might include spots under trees, or along the north side of your house.

Azaleas are members of the Rhododendron genus, and similarly, azalea's thick leaves can be evergreen in the South and deciduous in the North. Flowers return year after year, blooming perennially.

Azaleas prefer a little sun and a little shade. Plant them in blazing hot sun and they may suffer leaf scorch or become targets for leaf-sucking pests, such as spider mites and lace bugs. Plant them in dense shade and they won't bloom.
