Question
I live close to Dayton Ohio and was wondering when to reseed and also when to put the last fertilizer down.  Should I fertilize first and then reseed or just the reverse?

Answer
Hi Peg;
I don't use fertilizers.
I don't use any chemicals on my lawn.
Fertilizers kill beneficial miocrobes that enrich the soil.
These beneficial microbes will enrich the soil and when the soil is rich, there is no need to add nutrients.
Fertilizers add nutrients then wear our or wash out of the soil with rains and watering.
Sugar keeps these beneficial microbes alive, or you can use dry molasses. I prefer the sugar as the smaller bags are easier to handle and I can buy it when I buy my groceries.
I apply 1 pound per 250 to 300 sq.ft. of lawm, each spring and fall.after I apply it, I water it in well.
O just broadcast it by hand.
Weeds like poor soil and will not trive in rich soil. so if you make your soil nice and rich, weeds will not grow in your soil.
I have a thick, dark green weedfree lawn, and I have put nothing on it for 7 years except sugar, and of course kept ot watered well.
When I used chemicals, I battled weeds, grubs ,fungus and all sorts of lawn problems. Now, I have none.
I don't understand why you are reseeding your lawn.
The only reason I can think of reseeding is if you use an annual grass like annual rye.
I would recommend you use a perinial grass that does well in your area.
I am sure burmuda does. Burmuda does well almost everywhere.
burmuda spreads by runners, so after you seed in your lawn and it starts growing, any spare spots will fill in shortly.
Grasses like fescue and bluegras that grow on a single blade, have to be seeded in bery thickly to cover completely, and any bare spots have to be seeded in.
I recommend a grass that spreads by runners. They are much easier to keep a full thick lawn.

I found a couple of sites that might give you ,more information about lawn grasses in Ohio, than i can give you.
