Crabgrass starts germinating when soil temperatures are 50 to 55 degrees F for ten or more days and germination can take place over a 6 week period. Pre-emergence herbicides provide excellent weed control for crabgrass by preventing the weed seed from germinating, but it will not kill any newly sprouted seedlings so timing is really important. Usually late March or early April are good times to apply pre-emergence control in your growing region.
