reseeding

My lawn is very damaged with grubs.  I have tried Grub X with no results.  I also have a weed problem.  I really need to place top soil and start over but I wanted to try and salvage what I have.  I aireated my entire lawn and de thatched ( I really needed that).  The grass roots are not deep rooted.  I think this is probably due to alot of chemical use and to much water over the summer.  I have decided to use the tall fescue to redeed.  Obviously with the grubs and poor soil condition I need to do more than reseed.  I wanted to treat with milky spore (my grubs are still alive).  Can I do this while I reseed?  I need to eliminate the grubs or my problem is still there.  Also I am wanting to go organic.  Should I mix peat moss while reseeding?  What variety is best for this application?  Is there a natural product to use to speed germination?  I am taking my soil to be tested.  Im certain my soil needs TLC.  Can I apply natural fertilizer such as corn meal before the deep freeze or how long after I reseed should I wait?  I desperately need help, and with KY weather my time is running out.

Have you read this page about lawn care? Although I haven't had to deal with grubs personally, I wonder if improving the health of your lawn will decrease the numbers of grubs you have to deal with.

So many questions ...

Yes, you can apply milky spore and seed at the same time.

How deep is your soil?  What is under your soil?

Don't mix peat moss with your seed unless you have determined that your soil has a high pH (peat moss has a really low pH).  Compost would be better than peat moss.

Don't apply any fertilizer until the grasses are at least three inches tall.
