Answer: Azaleas grow and flower best if they receive shade from hot afternoon sunshine so plant yours where they will get morning sun and afternoon shade. Unless you want to grow a hedge with your azaleas, space them 4-5' apart so they'll each have ample room to grow without crowding. If you want them to grow into a solid hedge, plant them about 3' apart.
Best wishes with your new azaleas!
