Azaleas require an acid soil for best growth. However, they can be grown successfully in soil of neutral pH if an ample amount of acid peat is used for backfilling around the roots and if the plants are fertilized once or twice annually with an acid fertilizer. Since azaleas have a fibrous shallow root system, they will need water during dry periods. A mulch will help retain moisture. Avoid poorly drained soils.
