A professional is the best bet. If you do it yourself...treat it first with Ortho's liquid weed and crabgrass killer. Make sure it includes quinclorac. That should kill whatever weeds and crabgrass are present. Then apply the Halts step 1 to prevent any additional crabgrass seeds in your soil from sprouting.
You are not alone--going to be a tough year. But maybe frost will kill the early crabgrass...frost is common in April.

I have some experiments to see if crabgrass control like dithiopyr will kill early crabgrass. I also have a few pots of crabgrass inside for future tests of chemicals.

It is, everyone here has been done with pre-em for crabgrass for the last two weeks.

Even my supplier is out and not getting anymore unless they get a large order.

Rule of thumb, put it down as soon as the Forsythia's bloom and before the lilacs bloom, and they are long done blooming here.

bartjr is in central NY, which is NORTH of me.

how are you sure bartjr has crabgrass? when we dont have any here and are usually a week or so ahead of his area for GDD's???

we just started our first round this past week..Forsythia are in full bloom, ..and besides since when did professionals start going by forsythia and lilac blooms, we go by bradford pear blooms

...or better yet we use products that dont rely on a flowering bush to tell us when to apply something to the lawn

ALL of my suppliers have not even put a dent in the pre-emergent supplies....

Germinating CG looks nothing like the mature plant, you would have been pulling up over the past 2 years...

CG germinates with 2 rounded cotyledons, yet still pointed...

Someone who knows how to post pictures easily should post a picture of germinating CG...
