Question any suggestions beside remove entire plant and burn ? We are in Clarksburg
Md . Maps will say zone 7 but it seems like zone 6 is more realistic . We have
lost multiple plants including Rugosa Sarah Van Fleet, New Dawn,Alba
Maxima
KnockOut, Jazz , Shailers Provence is the only one that has come back healthy
after removing all sick tissue. I've tried going after the mites (carriers) with
Avid ..any suggestions would be appreciated thank you
AnswerRose Rosette is the worst problem a gardener can face with their roses. Because the mites are airborne there really is no way to keep them down. They do seem to sometimes attack certain roses, but the mites are in certain areas and all roses can attacked by them. Much research has been done on Rose rosette and they have found that the multiflora species rose that has gone wild in some areas, is the carrier for these mites. Here is the latest information on Rose Rosette for you.
