Hansie, Thanks for your input! It is definitely stiltgrass...physical description matches AND the deer won't eat it! I can't bring myself to go the chemical route. This property is wild...early spring there are ephemerals...these get going way before the stiltgrass. Then there are patches of sedge, goldenrod, dogbane etc that I assume over time would maybe...hopefully...become stiff competition for the stiltgrass. Before I knew what this stuff was I was pulling it out and removing it....worst thing I could have done....spread seeds all over AND left bare dirt. This fall I have left the stiltgrass in place, bought all the mulch I could afford, collected coffee grinds, cardboard, leaves....anything I could find and I am covering all the worst patches w/this. My understanding is that the seeds are very small and require light to germinate. They also don't like rotting substrate....so if I can "smother" the bulk of seeds then maybe what does come up will be more manageable. I understand that w/all this smothering some other plants may be affected but in my experience they won't be killed just set back a bit and maybe not at all if we get enough rain to rot all this stuff down. I just wish I could hear from someone else who may have attempted smothering w/stiltgrass...have you ever tried this method?

Looks a lot like immature milo seed, the reddish seeds found in many birdseed mixes...

A grass (maybe switchgrass?) Was planted in that area several years ago, but this looks so ordinary I'm not sure if it is not just a weed. I mulched around it just in case it is worth keeping!

It looks like you may have the same two annual grasses that get in my lawn this time of year. I am not positive of the ID, but one is very low growing with little white seed heads that I'm pretty sure is Poa annua 'annual blue grass'. The other I think may be annual ryegrass. After they sprout the only way I know to kill them is pulling them. Sometimes I have to use a digging fork to loosen the roots. The most important thing is to get them out before they produce seed from which next year's crop will sprout. You may be able to prevent them next year by applying pre-emergent granules in the fall at the proper time for your locality. Yes, it's work, but getting them out becomes a rather pleasant obsession making the efforts a little easier. I wish you well.
