I did a lawn renovation last year, and this seems to be coming up in multiple places. I didn't use a pre emergent yet as the soil temp is around 45. It pulls out as a clump.

Any help with what this is, and how to get rid of it? I used TTTF blend and peat moss. No hay etc.
Thanks

Looks like chickweed. I just used SpeedZone to kill some off.

It's probably rather hairy bittercress. But the treatment is the same.
