Jimmy,

The precise answer depends on the active ingredients in the crabgrass killer.  This information will be on the product label (which, by law, must be followed exactly).

Most retail crabgrass killers are only labeled for use in turf and contain quinclorac and other broadleaf weed killers, which will kill nearly all flowering plants that are contacted with the product.

Please let me know if you have further questions.
