Need advice on overseeding
Until this year I have had a beautiful organic lawn. I use soy bean meal, milorganite, and various organic fertilizers and cut my grass at 3" and mulch mow.
This year my lawn has been overtaken by poa. I don't want to use Roundup or any chemicals to kill off my lawn. My question is would it help to overseed my lawn this fall with a good tall turf grass. I would expect to use (or hire a landscaper to use) a slit seed applicator, thus gaining the benefit of aeration at same time as overseeding. Should this take care of my poa problem next year?
