Rhodies and Azeleas

I have always been good at keeping my Rhodedendrons alive and in good condition in my front yard. But, I couldn't understand why my Azeleas that I purchased last year kept dying. Well, last term I took a soils class and the instructor suggested that it was probably the soil. Rhodies and Azaleas like alkaline soils and where I was planting them was right next to the lawn which needs a more acid soil. To avoid this, try adding dolomite lime. That will change the pH level of the planting beds.
