They are a bit susceptible in certain areas to some of the fungal diseases, such as Rust, Leaf Blight, Fire Blight, and Powdery Mildew, so they perform best in production with some fungicidal treatment. If fact we have seen them sprout in the spring, wilt back from desiccation, then rebound strong with adequate watering. From our experience, they transplant rather easily, but do prefer a sandy loam, well-drained soil for optimum growth. However, they respond well to corrective pruning and can develop into outstanding specimens of form and character.
