Crabgrass – Pre-emerge Application
Q: Please tell me as accurately as possible when to apply the pre emerge for crabgrass.
A: The exact timing depends on soil temperature. When soil is 50 degrees F. and rising, crabgrass seeds start germinating. This soil temperature typically occurs in early March in the Atlanta area but there is no harm in applying pre-emergent in mid-February.
