That low growing, bright green grass was probably poa annua (annual bluegrass) --- it clumps up really low in winter, in the spring is produced about a billion seeds, and then dies in the summer.

for my dog, we planted KY31 tall fescue year. This turned a swamp backyard into a lush green playground. ky31 will be the only living thing that survives a nuclear war. This year, I overseeded with Titan RX turf type tall fescue - another hardy and durable fescue that is known to "fill in" bare spots over time similar to Kentucky Bluegrass (but much slower).

I assume you have a Bermuda lawn no. Generally I like too steer people away from overseeding rye into bermuda because the rye delays the regrowth of the Bermuda in the spring. But I can see you're going to do it anyway. Look for dwarf rye grass seed. The dwarf variety is very slow growing and may not need to be mowed all winter. But as winter comes to an end (early March), do mow it down low to allow as much sun into the bermuda as possible.

owlnsr - you mean there won't even be cockroaches running through the ky31 eating twinkies after the nuclear war?

Please, after nuclear war there will be cockroaches, K-31, and Cher.

Hey, she's survived everything else.

Thanks for the help everyone. It surely isn't my preference to do something that then forces me to do the very thing I'm glad is ending until the summer. But the grass turns brown etc and then the dogs like to play where the holes are and make it worse. Yes its pretty much a mix of Bermuda and Centipede.

So I should look for some type of Kentucky Bluegrass instead? What about the dwarf rye grass. How do they compare. I'm guessing either I would need to order online?

It might also be that I have no idea how to apply the seed. The grass seed I was buying was not that expensive. All I have is a small hand spreader with a side crank labeled 1-2-3 on the handle. I guess I could measure the area to see just how much a bag should cover.

Thx
