I have established rose bushes in my garden and recently the tip of the branches on several have started to brown and die off. I cut them back but they continue to die off and eventually the whole branch dies off. What can I do to?
I am attaching a link to an article about rose diseases. It sounds like a disease called Canker that is kind of like cancer in humans. Keeping the bushes well watered and fed usually gets them to grow out of the canker though. You could give them a treatment of the Bayer Tree and Shrub granules their systemic action cures many disease ills. Follow the instructions on the label for shrubs/ornamentals.
