Well, you could dig them up, and move them, but I get the impression they're pretty far gone.
If it were me, I don't think I'd make the effort unless the roses had sentimental or historic value.

I think I might just consider removing them entirely.
If you have a good location, and you want more roses, you could start over.

The silence you hear is all of us nodding our heads in agreement with Jeri.....

I would dig them up and move them to full sun. If the ground isn't frozen, I would do it now. I think they will surprise you. I wouldn't add any amendments to the soil,just the native dirt that came from the hole. That way you won't stress them by changing their soil.
It certainly would be easier than moving the neighbors house or removing the yews,LOL!

One option would be to pot them and see if it'll be worth planting them. You could move them around to see where they do best.

You know I considered asking the neighbors to relocate their house but figured that wouldn't go over well! lol.

Thanks so much for your recommendations!

I think I'll try moving them and see how they do with more sunlight. This weekend I found pictures of each with bloom from the first year I moved in and it would be a shame to lose them. Either way I'll give it a try. After all if they don't come back the only thing I'll have lost is some time and elbow grease! :)

Thanks again!
