Q.

Early warm weather and crabgrass germination

Zone 62615 | xlineman added on March 20, 2017 | Answered

We have had an early warm spell followed by a hard freeze, in the teens several mornings. Will the freeze kill any crabgrass that has germinated and sprouted? Should I wait until soil temps warm again for crabgrass preventer or apply ASAP?

The frost is not likely going to kill the Crabgrass.
Spring is a good time to apply selective herbicides.
Check with your local County Extension Office for advise on weed control in your region.
