Bumping this because I had the same thing. A new healthy shoot, then it wilted over, and I don't know why.

Me too on Sally Holmes. Everything else in the bed is doing great.

Same thing happened to my “South Africa“ this spring, except it was potted and overwintered in garage. Initially Everything looked wonderful with nice new growth, then it started to wilt, eventually gone. I dug it up later and couldn’t see anything unusual.

Anyone can provide an explanation?

OK, what is this? An epidemic? My America looked beautiful. Full of new growth and all of a sudden I see a bunch of dried out shriveled leaves. It has NOT been hot here at all but nor have we had any freezes. I'm stumped too!

Leaves? Or the whole stem. I also got Rose Kane gertler on the whole stem.

I’ve had a few like that too - need to cut out any dead/ dying canes. I’m still pruning lol, the weather has not been cooperative. I’ve notice some that have the wilted leaves are not green inside when I cut them back.

I agree that this is winter damage and that you should probably tentatively start pruning back beyond the parts with dying leaves. You may see further down the cane some split canes or other damage, or the dark interiors of the canes like Dingo says. It's frustrating to have what looks like healthy green cane just give up the ghost a few weeks after robust growth, but it's just delayed effects of winter kill for the most part in my yard. I never consider winter pruning to be actually done till about mid-June, which is when I do my final "death march" to see what has actually survived, what pretended to survive but didn't (i.e. put out growth it couldn't sustain), and what was, is, and ever will be dead.

in the first picture, I'd definitely prune off most of those canes - cut below anything that is dark red, brown, or even starting to turn a sickly yellowish green, since in my experience those canes are on their way out and you don't want it to take the whole cane out if you can salvage a stub. I definitely wouldn't try moving it out of the pot for the time being since it's already pretty stressed and that might tip it over the edge. My philosophy of spring pruning is that a healthy stub is better in the long run for a rose than a marginal "might be OK" cane that I'm likely going to have to prune out later in the season. This can look different in different yards or for different roses, but I expect most canes to die on most HTs, floribundas and minis. Any surviving cane is a welcome surprise after pruning. If the graft is intact (or roots survived, for own root plants) the rose can come back surprisingly well.

I'm keeping my fingers crossed for my Sally Holmes, but I think she's a goner. : ((

Well duh! I had that happen the last polar winter and had forgotten all about it. Will go back and reprune and see what's left of it. Thanks everyone!
