Power Rake and Overseed or Slice Seeding?


LawnSite Member
How am I going to get the best results to thicken up a thin lawn? My lawn is about 5500 sq ft and has some bad spots from heat stress and foot traffic from the kids. I live in Indiana my lawn is Kentucky Bluegrass (soded 9yrs ago) and has about a 1/2 inch to a inch of thatch. Would I get better results if I power rake the entire lawn and overseed or would you suggest slice seeding the thin spots or the entire lawn?

slitseeding will also remove thatch as well as seed. This is what I would do:

(1) move the grass low - about 1" - and bag clippings
(2) Slit seed in two directions - n to s and e to w - with out any seed in the hopper and pick up any thatch on the lawn
(3) make two passes again with seed in the hopper. If you see a lot more thatch being pulled up, consider making two more passes with out seeding.
(4) After you seed, apply a starter fert and keep the top 1" of soil moist - water 3x/day about 10 - 15 mins a day.

Good luck
