crab grass removal
There are several products on the market for crab grass. One that seems to be effective is Ornamec, a post emergence chemical herbicide. Agralawn Crabgrass Killer is an organic product that is worth trying. My best advice is to contact your local Cooperative Extension Office (blue or yellow pages) and get their recommendation for your particular problem in your region. They can also give you advice about the overall health of your lawn.
