Hi Tim, I asked the question about the perlite to reduce the weight of the container. Since then, I have done some research and found that some people use something called styrofoam packing peanuts to fill the bottom half of the container. I plan to do it in September and will mix the soil with perlite. The plants I have are hydrangeas, azaleas and knockout roses and I don't believe the roots go down very far.
