crabgrass in fall

I am surprised--crabgrass around here is looking very brown. Not dead but looking very much on its last legs. Lowest temperature has been 41 degrees.

I suspect that after a temp of 45 degrees, crabgrass is injured so that almost zero new growth is possible.

What does your crabgrass look like? Got pictures? Does this mean you could have sown grass on top of crabgrass two weeks ago? And your new grass would come up through the dying crabgrass?

Does this mean you could fertilize about now without stimulating any growth from crabgrass?

I just put down a fert with Em with no concern about Crab Grass. I suspect the demension will stunt mature crab grass but I am not concerned about it flushing up. I will do a post in about a month but again not targeting CG.

I've noticed that here too... no more CG at all... in fact I noticed today just how bad some lawns have gotten because the CG took over several nice lawns during the course of the hot summer...

That's funny... we've had quite a bit of death in high maintenance lawns because of irrigation problems this year,,, and now we see these brownish, purplish patches everywhere...
You are right, there would have been large areas that would have been only dust had it not been for the CG...

I didn't realize how much more overseeding needs to be done...
