For the past 4 years we've been primarily focused on lawn mowing and other small jobs. We are looking into adding a fertilization service to our business, possibly next spring. I have a few questions if anyone can help: Do I need a license if I am applying fertilizer only? How will adding this service affect my liability insurance, we currently have a $1 mill. policy. Are there regulations regarding storage of fertiilizer products? Thank you in advance for all of your help.
