Now that I've gotten some guidance on the Leucadendron, here's a question about PIeris: I have had several varieties: 'Dorothy Wycoff', 'Flaming Silver', 'Little Heath', 'Brouwers' Beauty', and they virtually all languish. I have a large garden with hundreds upon hundreds of shrubs and trees, and these are the worst performing plants that I have. The 'Flaming Silver' still look decent, but I lost all of the 'Little Heath' and 'Brouwers Beauty' and the 'Dorothy Wycoff' do not look great. My suspicion is that my soil, which is very slightly alkaline, is not to their liking, that they want acid soil and will not flourish without it. Anyone have any thoughts? If this is the case I will stop falling for them and move on!
