re: lime and fertilizer for grass

As said, if your ph isn't right then the grass/ plants won't suck in the fertilizer. Literally, so it's almost use less.

Also, you generally don't want apply nitrogen in the fall because it aids growth when your grass is trying to slow down and prepare for winter. It does more bad than good. As far as new grass though, I'm not sure what your best thing to do is.

Def get a soil test and if you go through the Ag college they usually tell you what to add for specific species. All states have a college that provides that for dirt cheap as far as I know.
