We're in the process of putting a chain link fence up in the backyard and we want some shrubs to cover part of it. We purchased 4 PJM Rhododendrons and 3 White light Azaleas. I'm not sure if these should be placed in groupings of the same shrub or alternating every other shrub. I'm not sure what is usually done to look the best. Also, I'm planning on putting a flower garden in. Should these shrubs be used as the back of the garden or should they be standing alone and the garden seperate. I'm obviously confused on what to do. Any suggestions would be great!!!!
