On 5/27/21, I purchased 27 knockout roses from the garden department. I had them planted in a new garden on 6/18/21 and they seemed fine. They were young plants and I believe the price was $9.98 each? They were fine for a few weeks, but suddenly began to shoot up in an unattractive manner. I assumed they just needed pruning. About two weeks ago, I noticed they produced mangled flowers and leaves, so assumed it was fungus, which I immediately treated. However, it got much worse. Both aspects became increasingly bad and were evidence of disease. Today I discovered online that they have a disease called Rose Rosette disease which means the plants must be destroyed. One article says if you cut off the infected canes at the very bottom, there is a slight chance to save them. I began that today, but discovered that there were many canes that were cut off long ago and had died and turned brown. Some were smaller and some quite large. I never had trimmed a cane. I think these plants had the disease before I bought them and the infected canes were removed. I have pictures of those brown canes and of the diseased roses on my phone so can send them separately if requested. Can email photos if you give me directions
