Need help diagnosing dead rose

6 years ago

I thought I’d try this out, with a different post. I’ve got a window of nice weather to replant in this spot, but not sure if I need to remove soil or let it rest. Does this look like any kind of bacterial problem? Many thanks!! 😀

This photo shows the split cane...could this have killed it?

Perma,

I am trying to tell from the picture.... did the graft union turn black and die from the bottom up? That is what happened to the roses that I lost last year. No one was able to diagnose the problem.... I took mine to the rose society and the local rosarians were not able to decide what caused it.....

The way mine died was that the canes were nice and green.... they were even blooming... but the graft started to get dark.... and darker and darker.... the canes remained green.... but then the graft turned completely black and then the darkness started traveling up the canes and then poof .... it completely died. This would happen over a two week or less period.

I certainly hope that doesn't happen to you.... and I hope that someone can diagnose it for you..... but even if that is what happened, I did NOT replace the soil.... I replanted and so far I did not have a problem.... yet.... and I hope I don't.

Good luck

Sharon

Could it have been soil nematodes in Florida? I doubt the split cane would kill a rose.

I don't think I see anything that looks like gall. That would be the only reason to remove soil that I can think of.

Thank you, Sheila! I don’t think nematodes, since I didn’t see any root knot lesions.

Maybe Dr. Manners will know, Perma. Florida is special.

Thank you, Sheila...that is so true!

No, I didn’t see any black...it was an own root plant. I just remember some yellowing of leaves, then all the leaves were brown and crispy. Then fell off. I kept watering it, hoping it would recover. 😢

Do I see a hole in one of the canes from a borer? The top pic, the small cane. Wouldn’t think that would be enough to kill it, I’ve got some with multiple bored out canes but I guess if it got down in the crown it would do more damage. If you’re sure it’s dead you could start cutting and see if it’s damaged.
