Azaleas grow in the landscapes of many homeowners, in a variety of colors, sizes and shapes, making them popular for many locations. Azaleas have different growth rates as well, according to North Carolina Cooperative Extension.

Types

Southern Indian hybrids grow very rapidly. The group of evergreen azaleas known as kurume hybrids are dwarf-sized plants that grow quickly, though not as fast as Southern Indian hybrids, reaching a final height of anywhere from 2 to 6 feet depending on the cultivar. Other varieties have a more moderate growth rate, though some cultivars such as George Franc grow slowly.

Fertilization

Azaleas do not routinely require fertilization, according to Clemson Cooperative Extension. Fertilizing azaleas does increase the growth rate, however, if nutrient-poor soil is causing slow or stunted growth.

Tips

You can attain the best growth rate possible with your azaleas by following good care and maintenance techniques. You should water your azaleas whenever the first few inches of soil becomes dry; mulch and prune annually every spring following flowering. Protect azaleas from cold temperatures as well, if your cultivar is susceptible to freezing temperatures.
