Areas of my lawn need to be reseeded plus I would use pre emergent like siduron in a granular form. My question is can I reseed and apply siduron at the same time. Also how siduron is applied per square foot Thanks Randall Olson

Expert Response

Normally you cannot use a crabgrass preventer when seeding but I did find this article from Rutgers explaining products that can be used.  If you have found siduron as a stand alone product, follow the directions on the label.  The label is always the law and the safest way to use any product.  Weed Control in Spring Seedings (
