Why is this cane turning yellow?

[vadr]

I have seen it on the tips of stems. They turn yellow for a certain length, then rot to that point.

But I haven’t seen it on a cane like this. I assume they are for different reasons. What should I do with it and how can I prevent this in the future? Another part of this same cane had turned yellow and I just cut it off. You can see where it used to be.

I’ll add that it looks like this cane appears to have damage near the soil line

Yes I see your yellow cane. I would remove it at the soil line. All the other canes look green plump and healthy. I noticed the rose is in a small square pot. Will you be repotting it or planting it in the ground? Sometimes my roses have a cane that is yellow and that means to me that it is going to die, so I just put it out if it’s misery and soon, a replacement came grows.
