Why Has Every Single Leaf Fallen Off My Climbing Roses?
I have 2 Zepherine Drouhin and 2 Climbing American Beauty roses planted on the sunny side of my yard. This is the 3rd summer I've had them. They all bloomed beautifully this year then, somewhere around the end of May, every single leaf fell off all four roses.
I did not add any fertilzer nor did I do anything different this year than I normally do. I did NOT spray even once this year for blackspot or any other disease and we did have a very hot, wet, steamy spring.
Could blackspot or some other disease have caused the leaf drop and, if so, will the leaves come back?
I have been busy this year with a lot of personal things so I did not happen to notice what kind of shape the leaves were in before they dropped (insect damage, yellowing or blackspot)so I'm clueless as to what could have happened and how serious this problem might be.
Please help if you can :-(
