I'm a homeowner in southwest Ohio. I aerated and overseeded in September and applied a starter fertilizer at that time. The grass looks pretty good right now. My question is, when should I do the next application of fertilizer and what type should I use? Should I use a fertilizer with a weed-killer in it (dandelions) or should I wait until next Spring or Summer do that? Shoul I apply a fertilizer now, or wait until December? Any help is appreciated.
