I want to start overseeding. I have been reading online and on this site, but can not seem to find the answer. So hopefully somebody can help. When overseeding a established lawn, do I use half the amount of seed as one would use on plain dirt. I will be using premium grass seed for my area. The rate is 1 pound per 250 sf. So do I use that rate or do I use 1/2 pound per 250sf? Then when using starter fertilizer, how many pounds per 1000 sf? The bag does not say. If it does Im not seeing it.
