It’ll just become more of a maintenance problem as the years go by; best to deal with it now. I can see the fungus on the flowers and leaf burn, from the rough winter, on the 2nd pic you posted. It won’t transplant. Either resign yourself to feed it heavily (Holly Tone fertilizer) in late fall, and prune judiciously to keep away from house and gutters, or take it out.
Won’t a spray solution of soap and water wipe out the fungus?
