Landscaping licensing varies by state and by service. A general business license is standard; pesticide and fertilizer application for hire commonly requires state applicator certification through the state agriculture department under EPA standards; some states license landscape contractors, irrigation installers or tree work. Hardscape and grading jobs can need local permits. Check each service you offer.

Pesticide and fertilizer rules
Applying pesticides, including many weed and insect controls, for hire usually requires state applicator certification and sometimes a business license from the state agriculture department. Some states and localities also regulate fertilizer timing near waterways. Check your state's rules before offering these services and keep application records as required. EPA's applicator certification pages explain the federal framework.
Mistakes
- Spraying without certification
- Blowing clippings into streets and storm drains
- Trailer without proper registration and lights
Rules owners often miss
If you plan to add fertilization or weed control later, start the applicator certification process early; exams and training take time. Keep application records as your state requires.
