I have been searching and reading this site for hours now and I need some help getting my questions answered properly so that what I am doing for my business is all proper as well. First off I work in the Kitchener/Waterloo area of Ontario. I started off with an aerator and of course it exploded into people wanting me to do other stuff for the lawn. So I need these questions answered. 1. Do I need a license to put down regular granular fertilizer? (Scotts Turff Builder and Winter Care. Nothing with weed controls. Fertilizer wont be stored, just bought for daily use.) 2. To spot spray for weeds do I need to get a pesticed license? I wont spray for grubs or anything like that. Just broadleaf weed spraying. 3. Are permits or other papers required for aerating, lawn edging, cutting, trimming? I would greatly appreciate anyone that can help answer my questions and better educate me.
