If you're north of zone 7, your local nursery has to be wrong about
identifying green patches in your yard at this time of year as crabgrass.
It's still too cold. The few grass patches in my yard now (zone 6b) are
patches of tall fescue. I have no idea what perennial grass you have in your
yard.


I am in Zone 9, Southern California. It is not a perennial grass. It is an
annual grass that will be gone on its own in a few months. The color is
light green and it grows in spreading clumps.
