how long does it take the crabgrass preventer to start working? i put some down about a week and a half ago and the grass is the deepest green i have ever seen... but it also said that it had a crabgrass preventer in it that would work up to 4 weeks after the crabrass has puped up and it was also supposed to kill broad leaf weeds and i still have clover and dandilions coming up..... is there something i am missing?

The winter annual broadleaves you see germinated last fall and are now growing to the point that they are noticeable. A post-emergent is needed for control. Since you mentioned that the label on the product said it controls crabgrass up to 4 weeks after germination I can guess that the active ingredient was Dithiopyr, the active ingredient in "Dimension." This product works well as a pre-emergent for a variety of weeds but the primary function is crabgrass control. Manufacturers include the term "control" on the label even if it is only a small reduction in the population of broadleaf/grassy weeds.

I think you are a home owner and need help in getting rid of broadleaf weeds in your yard. Go buy a dial a sprayer or a hand held sprayer and some ortho weed be gone. mix it 2 ounces chemicals-per gallon of water and spot spray your weeds this will kill all the broadleaf and the clover too you might have to do it twice but it is effective.
