This is a red Knock Out Rose Bush which is three years old.
Can you please tell me what I need to do. I thought of doing a hard prune at end of blooming season abut not sure. I have never had this before and don't want to lose them.
Thank you
Theresa M. Campbell

Douglas Hunt on Jul 12, 2013An overabundance of thorns is one sign of rose rosette disease. Knockout roses are not immune to the disease. You should definitely keep an eye on the plant. If it is rose rosette, there is little than can be done other than remove it: http://www2.ca.uky.edu/agcollege/plantpathology/ext_files/PPFShtml/PPFS-OR-W-16.pdfHelpful Reply

Laurie on Jul 12, 2013I totally agree with Doug, you have rose rosette. While the Knockout roses are very resistance to disease, it was the first type to get hit with rose rosette here in the Dallas area. Rose rosette is spread by mites and there is no cure. You should remove your rose right away and trash it. Do NOT compost it! Here is a link about the disease: http://www.ars.org/pdfs/rose_rosette.pdfHelpful Reply

Theresa Campbell on Jul 12, 2013Thank you very much. It looks like that is what I have on my rose bush and will have to check out the other two rose bushes next to it. Very good and informative website listed above. Thank you to everybody for helping me with my problem. I love this home talk website. It is awesome.Helpful Reply

Catherine Smith on Jul 13, 2013Agree with Laurie. Pull them all up and destroy the plants. Do NOT plant roses back in the area again. No rose is completely disease resistant Theresa, but Knock Outs are tough. Unfortunately this rosette stuff is the pits. Try them again in another area.Helpful Reply

Susan From Colorado on Oct 25, 2014I just found this question and I am glad I did.. I recently moved 1000 miles and had our gardener friend pot all my roses for the long trip.. within the first season I was very disappointed that they got so few flowers, but also noticed these small thorns.. by the following spring they were all dead and I have been very upset as they had very special meaning for me.. but now I know the reason they did not survive as mine were also covered in these tiny unusual thorns and I just thought maybe I needed to cut the elder branches back.. that would not have helped according to what I am reading here, so thank you all so very much.. question.. should I discard all the potting mix in the pots they are in or will that be okay to pot something different in next spring??Helpful Reply
