Catnip from a while ago?

Some time ago I was talking with some folks about coffee grounds, and had posted that grounds would work or seemed to on my dry land plants. My catnip enjoys the grounds and I was wondering how that had worked for that individual or two that said they would try that. Mine are still green and grew like crazy this year .
Unfortunately; that is one of the few times about the plants this past season.....

coffee grounds draw worms- think its candy, even on dry land! they are good. They prolly did try the grounds.
