Is it to late to use the Scotts crabgrass treatment or should I move on to step two (weed and feed)? dandilions are already coming up all over the yard

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.
