Plant Requirements

When choosing a spot for your azalea bush it is critical that you take into consideration the specific needs of your azalea variety. Different varieties have different needs and many factors can affect the way your azaleas grow and flower. Don’t let this intimidate you, because azaleas are very hardy and adaptable plants.

Sunlight Requirements

Most azaleas prefer partial sun and partial shade. It is best to plant them in an area that receives morning sun and afternoon shade or an area that receives filtered sunlight throughout the day. Although this is their preference, they are still very adaptable plants and will grow in a variety of sunlight conditions. Many azalea varieties can handle more sunlight if they are properly watered. Azaleas that are grown in full sun will have shorter stems and more blooms; however these blooms will not last long. Azalea bushes grown in full shade will have longer stems and fewer blooms, but the blooms will last longer.

Soil Requirements

All azaleas require the same soil. These shrubs thrive in acidic well-drained soil. If you are unsure about the pH level of your soil, you can submit a soil sample through your County Extension Service to have the pH levels and soil nutrients evaluated for little to no cost. To test the drainage of your soil, dig a hole and fill it with water. If the water drains out in a couple of hours, you have good soil drainage. If the water is still sitting in the hole after 24 hours, you have poor soil drainage. To help with poor drainage, you can either build a raised bed or mix additional components into the soil to allow for better drainage.  Azalea roots need access to both oxygen and moisture. In wet soil, the roots will grow close to the surface to get oxygen. In dry soil, roots will penetrate deeper into the soil in search of water.
