Problem Rose Buds
This is my second summer in a Minnesota home. Several rose bushes came with the house and they were in terrible disregard. This spring I pruned aggressively and the plants seem to be much healthier.
My problem is that the petals on the buds are lumpy and warty - every bud, every bush. A few have opened to blooms and they are irregularly-shaped and weird. I have not noticed any bugs on the plants. Any thoughts?
