Title: Rose canker in roses on cedar posts
Answered by: Joe Marcus
QUESTION:
While visiting the wildflower Center I saw that some of the plants were growing on trellis' made of posts cut from cedar trees. I made a trellis for my climbing rose bush and where the stems touched, turned black and the rose also turned black. Are there only a certain kind of plants that can climb my cedar trellis?ANSWER:
It is likely that your roses were attacked by a fungal disease which gained entry through contact wounds caused by rubbing against the rough cedar bark. The likeliest candidate would be a disease called rose canker. Many roses, especially the non-native ones, are susceptible to a host of diseases. Pruning out diseased canes and using good cultural practices may be all that is required to rejuvenate your rose.More Diseases and Disorders Questions
