Hello All, My lawn is split in two sections. The front (and thirty feet into my back yard) is sodded that is in excellent condition. Beyond the sod is an area that was tilled and seeded in spring of '09 (clay soil) that has been quite a bit of work to get where it's at now. I aerated and overseeded last fall, today the area is full of a grass mixture (bluegrass which I like, and tall fescue which I don't like and must have been seeded by my father in law when he tilled and seeded the area). The tall fescue is currently dormant and this is evident in how a majority of this area looks like an even combination of green (bluegrass) and tan (because of the dormant tall fescue). I've been told the only way to get rid (or crowd out) tall fescue is to kill it off. I started doing that this spring when the tall fescue clumps were clearly sticking out like a sore thumb. I started with Roundup and now I'm regretting that because now there's just a few patches here and there of dead matter/hard soil that I'm going to have to patch up. Since I am not going to completely kill off the tall fescue (because killing and re-sodding is out of my budget), I have a plan for this fall which is this: 1. Aerate that area as much as I can 2. Overseed the area (what to overseed with that will help crowd out the tall fescue???) 3. Water it all in, cross my fingers and see how things turn out (I won't see results until a year later really) Thoughts on this and what to overseed with after the aeration?
