So I have a rosebush (Snowfire) that has a lot of thorns all of a sudden and only on one stem. I was wondering if there is anything that I can do for it or if I'm out of luck and just have to dig up the plant and throw it away.

Is it possible I can just cut that stem off I know my plant will go into shock but loosing one stem to me would be more preferable than to loosing the whole plant.
I would greatly appreciate any information you have to offer.
