deformed leaves and buds on roses
I planted a rose garden last summer and the blossoms were beautiful until the end of the summer when the stems lost all their leaves and got fewer to no blossoms. I was told that the humidity and lack of rain/water were the culprits. This year,some of the leaves are curly/dwarfed, and red, and are not growing well. Some also have a white coating on them. Tried fertilizer, systemic fungicides, no change. What should I try next?
