Equivocal herbicide results

2 weeks after direct application to crabgrass, crabgrass still viable and growing. Should have used Round Up, even if would have killed grass.

This product is excellent in killing crabgrass. It worked just as advertised if used according to the directions. It's a bit pricey, but definitely worth it.

This kills crabgrass in about a week after spraying. May need a second application to get spots you missed, but it kills it dead!
