crabgrass

It looks like a grassy weed to me, if it is not crabgrass, which typically has wider leaves. Examples are poa annua or poa trivialis. You would need Tenacity to get rid of it (kills grassy weeds while leaving the normal grass alone. It's a bit pricey, so you might cut it out of the lawn if there isn't too much of it.

I think it looks more like poa trivialis. I am already battling poa annua and this one looks different.

I have tenacity and will give it a try. Thanks for the suggestions.

It would help to know where you live and what kind of grass you have? Some grasses are sensitive to certain herbicides.

It is definitely NOT crabgrass. Crabgrass is an annual that comes up from seed every year and then dies in the fall. Anything in the lawn right now is not crabgrass. It is tough to tell exactly what you have there, but the most common clump grass is tall fescue. It tends to be very noticeable in the spring because it starts growing sooner than other grasses.

While it is considered a weedy grass, there is no selective control and so most people just put up with it. You could kill it with Roundup but you would then have a dead patch and would have to re-seed or re-sod the spot. Tenacity will not kill tall fescue. There are newer varieties of tall fescue with thinner blades that are being used where a tough drought resistant turf is wanted. Beware of the grass seed called Kentucky 31. Despite "Kentucky" in the name, it is actually a tall fescue variety that does not belong in a home lawn.
