I have grass-like weed growing rampantly in a damp and shaded part of my lawn (in Northern California). It spreads via runners up to 3ft long or more. Here are some pics of bits I pulled up:
Can anyone help me identify this? Is it some variety of crabgrass?
Suggested treatments to eradicate the problem? Am I correct in thinking that intensive treatment should be administered in the early spring?
TIA
