http://ohioline.osu.edu/hyg-fact/4000/4010.html Apparently it's very hard to get rid of. I've been pulling it out and have gotten about halfway through the mess, but I suspect the roots I missed will return once I seed and water the area. Of course it's right in my front yard by the driveway. I hate to think about it but roundup may still be a need.
I found Alfalfa Meal for 20 cents per pound at an area feed mill. I also stopped at Agway and found that they have a Ringer knockoff which is an organic 8-2-4. Also, they had Milorganite 6-2-0 and something called Espoma Organic Lawn Food 18-8-6. I bought the Espoma because of the higher Nitrogen (supposedly from organic sources).
My plan is to
1) Mow the lawn extremely low.
2) Rough up as much as much of the 6500 sk as possible using a trusty metal rake and dethatching rake.
3) Lay down the Alfalfa Meal using an Earthway spreader my neighbor has.
4) Hand seed the entire area or use the Earthway (lazy)
5) Spread the 18-8-6 fertilizer to get the quick N fix for the existing grass.
6) Water (if it doesn't rain)
How does this sound?
