so i hired someone out to spark somting to kill off the weeds at one of the locations i take care of, a gas station. now they want grass planted where the pesticides were sprayed... most of the locations that were sprayed were over wood chips and i think that if i remove them and the black anti weed growning cloth that the soil underneath will be fine, but what about the areas where the bare dirt was sprayed? will the pesticides prevent the grass seed from growing, or will 2 weekd have been enough time for it to disapate suffucently? what do i have to do to make sure that the seed will grow. i also will add that this is in chicago and that seeding now isnt the best idea, but the customer demands it and will not sod.
