Okay- I have repotted my picotee MG in Scott's Premiun Potting Soil ($5/ cu ft). Here is a picture. We will see how it does. What I was using before was Evergreen Topsoil. It is made of pine fines, hardwood fines, forest products, sand and fly ash. It comes from Muscle Shoals, AL. I have used it liberally in the last year, which is unfortunate. But I am getting varying results depending on the plant. What is the pH requirement for I. purpurea and I. nil?
