New grass growing in Meadow, is it invasive & can it just be pulled?
Looks like barnyardgrass, based on the seed head. This is a weed from Asia. Just pull it and put the plant (or at least the seed heads) in the garbage. Don't compost them. You can throw the rest of the plant on top of brush pile and let it die. By the time it settles to the soil, no danger of it propagating.
