Can anyone tell me what is a wrong with my roses and what I can do about it? The leaves on all my roses are yellow with dark green veins. Almost all my roses are affected, both old and new.
I have been spraying with Rose Clear since early in the year but it is not helping. I have had other diseases in the past, black spot etc but this year only this.
Can Anyone help
