I'm not convinced it's too late for crabgrass control. 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. The compound prevents the weed seed from germinating, but it will not kill any newly sprouted seedlings. Although you should watch the weather - late April to early May is an ideal time to apply pre-emergence control in your gardening region.
