Guy: "my father in law is so great with lawns so I called him when mine was all brown" Father: "I told him to use scotts turf builder. He said 'I have a bag of this other stuff'. I just threw that right in the garbage!" Technically you can throw non-pesticide infused ferts in the garbage but is Joe schmo gonna know the difference between "turf builder" and "turf builder with halts" or any 'weed and feed' for that matter. Not exactly the right message to send.
