an organic grower feels that rose rosette disease can be cured
I wonder if they actually "cured" herbicide damage. Next door was a non organic grower with "damaged" roses. Since more than one cane seems to be "damaged" it does not appear that this "cure" is simply due to cuuting off a cane below the point of infected wood.
Also, the second link (see the third picture) shows a cane with black spots "The stems may show black splotches." as if the black splotches are a symptom of rose rosette virus. Can anyone comment on this aspect?
