Sue ....
I should have added, "There are a lot of right ways to grow roses." ...
People have been successfully growing roses in all climates without knowing the botany of the plants, or any of the science I had to learn.
I don't know it all and never will know it all. I do think knowing the botany helped me create this garden with lousy soil and a climate so very different from any climate I had ever experienced. If anyone can use the info above to grow better roses, then I have followed another one of Ralph Moore's mantras ... "Knowledge not shared is knowledge wasted."
