Sassafrass - You lucky girl! Wow! Those are some beautiful roses there.. mulch & water them nicely and they should be just fine! That's another reason why I don't want to ever move.. I can just see someone ripping out all my roses that I've put painstaking time/blood/sweat/tears into! (especially the blood part)
I've seen galls on scrub oak, but never spiny galls before. Yikes! But they look super cool!
