As Ric said, a weed-n-feed contains a herbicide. Therefore, you need licensing. If you are thinking of getting Scott's products from a local store, Steins, Fleet Farm, or wherever, and applying it for customers, you can't. As soon as your service is "for hire" you have to be licensed. Also, you could never compete price wise with products from retail stores. They are almost double what I can buy my product for. If you have further questions, just e-mail me with a phone number and we can talk a bit on the phone. That would be easier than posting back and forth since were both in the same general area.
