Hello folks, Just wondering if anyone has experience with the red flower carpet rose. This is my 3rd year with them in the garden and for some reason they are covered in black spot this year (unlike the last 2 years) and are slowly losing all leaves... Any ideas whether it's something I may have done? I can't think of anything I did different this year. Anyone have this experience with these? They are in a full sun location (greater than 6 hours of sun a day). Thanks.
