Product Q&A

Answer:

We are sorry if you did not get the expected results using Fertilome Weed Out with Crabgrass Killer. Keep in mind that you should allow at least 10-14 days to see results when using post-emergent herbicides. If the crabgrass is mature (past the 4-tiller/leaf stage), then you may need multiple applications to completely control the crabgrass. Please see our Crabgrass Treatment Guide for more tips, and let us know if we can further assist you.
