I would recommend fertilization in mid to late August for your area with 1 lb N/thousand using a high N lawn fertilizer such as Lesco 24-0-11. Continue to apply 1lb N per month through fall until your final application of winterizer.

Assuming you have fescue or rye grass and you use a chemical fertilizer like Scotts, then you should fertilize in late spring (Memorial Day), early fall (Labor Day), and late fall (around Thanksgiving, but more specifically it should be after YOUR grass has stopped growing but before the the ground freezes). The last app should be a high N fast release product. Do you have Kentucky bluegrass?

If you use an organic fertilizer you can use the same schedule and add an app on 4th of July. Organic fertilizers work biologically and cannot burn your grass even in the heat.

Using the holidays as reference can make the timing easier to remember.

Thank you both...

dchall the lawn is a fescue and KBG blend...

I thought I read KBG require more fertilizer.

Is that correct?

I don't think you have a lawn problem at all. Basically crappy genetic stock bowing out to the conditions. It'll likely come back fine this fall. How you manage the fall season is largely dependent on what is the predominant grass type in your blend. If just a cool season mix, treat it as such and take an average. So between high input KBG to as low as fine fescue, fertilize somewhere in between.

You have to cater your routine to what you have. Sounds like you are wanting more. That requires better genetic stock or going over the top with what you have in defiance of nature--that will require more pesticide use and cultural practices like core aeration.

It looks like a fescue and kbg blend. What's the fertilizing schedule for a blend?

Will an aeration and overseeding help?

Can I overseed with kbg

Looking at your previous thread, your grass looks pretty good and should bounce back with cooler temperatures and nitrogen. You can try an overseed, but looking at your pics again, the turf looks decently thick so seed may not be able to germinate. Aeration is up to you

Like J4c11 said, common practice is add most of the N during the late summer / fall time. I have a northen mix as well and use an organic approach (milorganite, SBM, and alfalfa) for most of the season until fall time and will switch to synthetics. How much you put down is up you, time and the pocketbook.

If you want to be super aggressive with N, google "fall nitrogen regimen".

Thanks Zeus, I googled fall nitrogen regiment. What program did you follow; there are several
