Rose Bush Care

Question

I live in Frisco, Texas in the Dallas area. I have purchased so many rose bushes, and I am always dealing with black spot. I have purchased rose fertilizers, systemic and the black spot control, to no avail.  I still have black spot. What can I do, if anything, to keep my roses? I love growing them. Is there something else I can do to keep them healthy? I grew them in California for many years, but now that I’m in Texas,  I am truly frustrated. If roses aren’t going to do well here, do you have suggestions of plants that flower for me to grow?

Answer 1

Give neem oil a try. It is a good, organic pesticide and fungicide that might help. Here is more information:
