Why do I have yellow leaves on my roses?

Douglas Hunt on Jun 25, 2012I hate to diagnose without seeing a photo, Beverly, but if your roses have blackspot, the problem is going to get worse without intervention on your part. This article from Michigan State's extension service has photos for you to compare with and suggestions for dealing with the problem: http://www.ipm.msu.edu/woodylandscape/blackspot.htmHelpful Reply

Beverly P on Jun 25, 2012Yes Doug, that is exactely what I have going on here, we went and got some Bayer Complete for Roses yesterday and I treated them all last night. I guess I'll keep my fingers crossed, do you think I should cut them all back this fall? All 10 of my roses have it, the yellow and lavender being the worst. Thanks for the info Doug!Helpful Reply

Douglas Hunt on Jun 26, 2012I would not cut them back until spring. Make sure you clean up all the foliage around your plants in the fall and dispose of it, do not put it in the compost pile.Helpful Reply
