Q.Why has my 15 years plus Rose bush developed branches with very tightly clustered thorns

Zone Parkton, Maryland 21120 | Anonymous added on January 25, 2020 | Answered

This has happened for two years now. I prune them off, but new shoots keep re-appearing with these same clustered thorns, and they do not produce flower buds at all.

Oh dear. It sounds like rose rosette disease and there is no cure. It is best to remove the plant.
