In early spring when seeding takes place, spring clean up, aeration, thatching, and whatever ever else, how long do you have to wait to apply pre-m? I"m defenatly getting my Pesticide license this winter for next year, deep thoughts come to mind..... How much to charge? What Pre-m can be used for? Around shrubs? In beds? Saftey? How long can customer not be on the lawn for? Any input? I"m just sitting here thinking of a plan for next year.
