Question
I have a lawn that is 3 years old. I live in southern Ohio (Cincinnati).I have over seeded each fall and spring. I have finally have got a full and pretty full lawn.
However, I have made the mistake on one of my seeding sessions of using Kentucky 31 tall fescue grass seed. It is thick, course, ridged, and very light green in color. The color really stands out compared to my other grass. It looks terrible.  The Kentucky 31 grows faster than my other grass, and I have to cut it often to make it look somewhat decent.  I hate the way my lawn looks, all because of a bad choice of seed.  I can live with the different thickness, however the different color bothers me allot. I have applied Scotts Step 1 w/ halts crabgrass preventer.  
My question is there any fertilizer or chemical that will 'green up' the Ky 31 to make it darker? Will Scotts step 2 help? Is there any solution for my problem other to deal with it or kill it all? It would take forever to kill each blade of ky 31 with round-up a blade at a time. Would a total or partial renovation be necessary to achieve the nice lawn that I have worked so hard on. I have pictures available of my lawn if that would help. Thanks

here's some ideas

1. buy a wick applicator(a long wand that you can put diluted roundup in) that has a sponge at one end and fill cap at the other. rub it across the turf being sure it only comes into contact with the tall fescue grass. make sure it doesn't drip any excess fluid onto the other grasses. you may have to let the lawn grow longer to expose the tall fescue more. you may have to repeat the process until all the tall fescue is gone.

2. or apply just scotts regular fert. at 1/2 the normal strength. wet the ground right afterwards. see if it greens it up better.

3. you could try mowing the lawn shorter(keep at 1 1/2"-2") than normal 2-3's per week for about 1 month. see if it eliminates some of the fescue. tall fescue needs to be cut at 3-4" tall to stay healthy.

at worse you could always do the hardest thing. i would think you probably have to spray the whole lawn area w/roundup, wait one week, mow(scalp) the dead grass, scarify the soil, and then seed it again.

or just settle for the different looking lawn in the neighborhood. it would be a novelty.
good luck
