Slit Seeder or Thatcher and Top Dress?

Last fall I did a major renovation of my lawn; aerate it, de-thatch it, and added about .25" of compost with new seed mixed in. The lawn came in great but a combination of creeping bent grass, nimblewill, and summer heat made several large dead patches (about 1/3 of my lawn). I used Tenacity about 3 weeks ago to finally control the creeping bent grass / nimblewill and just applied a second round. The question I now have is do I go through another laborious and expensive compost application again this year or can I get by with just slit seeding? I would rent a Bluebird slit seeder and use it a couple of passes without putting seed down to de-thatch it, then use a lawn mower to cut it low and vacuum up the de-thatching residue, and then apply the seed with slit seeder in two passes. Any thoughts or pass experiences with slit seeding? Also is it too early this weekend to do this or should I wait two weeks more? I live on Long Island, NY and plan on using again a seed mixture from a local sod farm consisting of KBG, creeping red fescue, and perennial ryegrass.

tjski,
I am going to do almost exactly the same thing to my lawn on Sept 9. I'm in the DC area so probably a little hotter here in terms of germination timing... Same situation, though. Complete reno last year... added about 3" of topsoil, reseeded the whole lawn... came in perfect! beautiful. lush, green, etc. Then the heat came and the fungus spread. Anyway, i lost about 1/4 to 1/3 of the fescue that had come in.

I am going to do the following:

1. cut low. Really low. bag all that mess up.
2. rented seeder
3. run that in 2 passes 'dry' no seeds to churn up the dead crud and carve some good slits in the ground
4. run the mower w/ bagger over it all to pick up the stuff the slitseeder carved up.
5. either fill the seeder and go in two or three passes OR use my broadcast spreader and put seed down that way
6. roll w/ 1/2 full roller
7. water 3X per day 10AM 2PM and 4:30 PM until the fescue germinates

So.... It looks like you have smililar plans. I'm no expert, but we seem to be thinking about the same.

My only question, and one you might consider too, is whether or not to actually put the seed down with the slit seeder or just use it to carve the slits and then use the spreader to lay down the seeds. Then roll it in of course.

Some experts might chime in on that one.

Good luck!

Plan sounds good.
If you lawn isn't very big, consider sodding it!
