I just moved into this rental in northern mississippi. Killing everything at once is not a option. My yard is about 80% crabgrass. I as wanting to do somethign inexpensive to improve the yard atleast a little bit by next summer. I have about 5 to 6 hours of sun a day. I was thinkin about letting crabgrass die this winter. Then using corn glu. preemergence early feb. and then overseeding in april. what does this sound like? how long do you have to wait to overseed after you put down corn glu.?? Does a fescus mix work grow good in northern mississippi.?
