Cheap bare-root plants, or any bare-roots planted after April, often suffer from canker and dieback. They have been held in cold storage since November. If conditions are not perfect, they can suffer freeze damage or dehydration. Discount roses have not been carefully inspected, culled, and pruned-- or they may be culls from a premium operation. Just prune the bad canes off, or to a bud eye at least 1" below any black or yellow bark. It looks like the healthy areas are growing well, so I'd leave them alone. Obviously the cane underlying the dead area on the tree rose has been physically injured so it cannot function. It is broken, bored by an insect, or girdled by a canker lesion. Water on leaves does not cause burning-- that's an old wives tale.

yankeesrule, There's a troll working Rose Forum right now, so be careful who you listen to. Especially ignore crappy advice from someone who has registered and started posting within the past week. Yellow canes indicate a lack of transport between the roots and stem, and the rose has already decided to abandon that cane when it goes yellow. It might be damage from last winter that's just beginning to manifest itself as a canker, or it may be a problem with the roots that support that cane. If you can get a bloom or two off of it, that's good. If you can keep some leaves on it, it will be better for the rose in the long run. If you cut it off, the rose may not have time between now and your early fall to grow a winter hardy cane between now and first freeze.

Glad you liked the photos, kathy. I got her because I was admiring a photo you took of yours several years ago--though whenever I focus on the plant itself, I don't know if that was good or bad fortune. But bloomwise I just love it. serena--like you, I adore differently colored revese petals. Somehow a touch of yellow at the base of a bloom adds automatic charm in my book. Kate

I love the changeable color of Peace and Chicago Peace. The color lightens and changes too as it opens so that's exciting too. Both of these Peace roses are great. You will have to watch and see if one is always darker than the other. I have two different Medallions and one is always darker. Maybe it's the location in the yard or just a difference between the two plants because they came from different sources. Thanks for sharing these fine looking roses. I always thought that rose was so lucky to have the name Peace.
