Thank you. In the same bed I have a late flowering clematis, the leaves of which have gone a pale green, look mildewey, but are not actually mildew and almost no flowers this year. I also have hollyhocks near the rose and clematis. The hollyhocks seem to be infected with multiple brown spots under the leaves and I am wondering if hollyhocks are susceptable to any virus's or fungus which can be transferred to other plants. I had my suspicions last year that the holyhocks were the culprits.
