I also noticed that places with plantago lanceolata and plantago maior (plantain) are free of crabgrass, but I don’t know how effective they are for combating this type of grass.I associate plantain with poor winter drainage. Perhaps that is what the crabgrass can't take. I recall from unknown sources that winter rye is allelopathic, and so makes a good smother crop -- so confirmation through hearsay.
