I did my very first overseeding today. Small job about 2000 sq ft. I rented a Bluebird seeder and found it to be a waste of $$$. 36 bucks for 3 hours + seed + fert + straw cover + time = about 25 bucks profit by the time I was done. Its a customers lawn and my mower did some of the bare spot damamge over the last 5 years so it was sort of a good will gesture. Now I have to wait and see if it works. Bad area. moss, dark trees and crappy soil but we will see. I used mostly a fescue, ky blue and rye (perennial) mix. Bid it at 100 bucks I am embarassed to admit but it kept me from sitting on my hands today. What do ya think?
