One VERY sick Iceberg Rose Tree
I planted my Iceberg Rose Tree in the spring & up until a month ago it was breathtaking. Then the buds started getting brown & squishy. I sprayed it with the combo Ortho Rose Spray that takes care of insects & disease both. Then someone suggested I use a commercial copper-based spray. Now my poor baby looks extremely ill. It has blackspot, brown crisp leaves, flowers that are half brown. I'm beside myself & don't know what to do next. Any suggestions? Thanks.
