What "weed" is growing in my lawn?
Throughout my lawn I have patches of this straw-colored "weed" that is slowly turning green as the weather turns warm. Please tell me about the identity and habit of the "weed" and how to eliminate it as each year there are more patches showing up in the lawn.

This is nimblewill, a perennial grass weed. Here is our website profile on it (it is on the RIGHT side of the photo): http://extension.umd.edu/hgic/nimblewill
Note that mowing too short encourages this weed. Turf should be mowed 3 1/2 , even 4" high. Also, it prefers shade, but does fine in sun as well.
It is very difficult to selectively kill a grass weed growing in a grass lawn. There is an herbicide called Tenacity which will kill it, but it is expensive. If your nimblewill is limited now to only a portion of your lawn, it is worthwhile to dig it up or renovate that part of the lawn (kill that part of the lawn and reseed it). Fall is best for renovation.
THANKS for the quick informative response!!!
You're very welcome.
