OK, so summer is almost over and I want to get my yard ready for next year. The things I would like to to are aerate, lime, and over-seed. I will probably roll in the spring. I know rolling is counter-productive to aerating, but is there any other way to smooth out my yard? Should I aerate and roll in the fall, then aerate again in the spring? I am currently mowing at 3", is there a time when I should begin mowing shorter? I would assume toward the end of August when it starts to cool off a bit. Is this the time I should aerate too? What I was considering was moving at about 1.5-2" and using a core aerator. Is that short enough, too short? Then come back and apply lime and over-seed. If I do this how long should I wait in between aerating and seeding, seeding and liming? Also, if I am aerating, I probably should not need to de-thatch the lawn. I am trying to get the lawn to fill in and green up. I am sorry for all the questions in one thread, but I thought it would be better than starting 5 different ones. Oh yeah, my grass is a mixture of tall/fine fescue and probably some rye/blue grass. I will probably over-seed with a full sun seed, probably fine fescue and/or KY bluegrass. Sorry I don't know more.
