This is first year rose Barock from Palatine. The rose was developing very slowly with red canes and not healthy looking leaves. I was thinking it's because of light lacking. Didn't know anything about RRD at that time,just cut the top. The rose was not developed later, new rad canes didn't turn green. Started to figure out what might happened and sent pictures to Master rosarian in my area. She confirmed that it's RRD.
I have removed this rose. Any suggestions how to prevent other roses from infection? They all look good so far. Made a lot of reading, but if you have a story how you managed it, please share!
