roses with black spot

valenzue62 added on March 19, 2015 | Answered

WHAT IS MY PROBLEM? I recently treated my roses for black spot. Now they are covered with tiny black spots with some leaves all black. The leaves turn yellow and fall off. I stopped using the fungicide and have removed as many affected leaves as possible.

How long ago did you treat your roses for black spot? What course of treatment did you use and for what duration? When treating black spot, you should not stop the prescribed fungicide treatment in its tracks because then it won't be as effective. A rose afflicted with black spot will have leaves that turn yellow with sometimes brownish edges and fall off. What you are seeing is a normal happenstance.
