Answer: Salvia May Night is usually considered easy to grow and generally pest and disease free, so I am not certain what you are seeing. It begins to bloom in late spring to early summer and then will repeat if deadheaded. Mine usually bloom very well through the fall until frost. They should be trimmed back short after freezing weather each fall. I would suggest you consult with your professional nursery staff and/or county extension to see if they can diagnose the foliage problems for you. If it is something that needs to be treated they will be able to tell you the most up to date recommendations including what to use and how/when is best to apply it. I'm sorry you are having trouble with your salvias.
