I had a small lawn maintenance business for about 4 years in Eastern North Carolina. A couple of years ago I sold out to go to work for the fire dept. It is hard to get away from the green industry (something you grow to love very quickly). I want to get back into the industry. I would like to start spraying and fertilization programs. Do you have any advice? Where should I start? It was easy to start lawn maintenance. I had a lawnmower, string trimmer.
