Fertilizer Rules for Landscapers in Miami-Dade: State Certification and the Summer Ban

Fertilizer is part of the job for most lawn and landscape businesses. In Miami-Dade it is also regulated twice: by the state, which certifies the people who apply it commercially, and by the county, which limits when, where and how much. This guide sums up both. It does not cover pesticides, which have their own licensing.

The state certification

Under s. 482.1562, anyone applying commercial fertilizer to an urban landscape must hold a limited certification for urban landscape commercial fertilizer application from the Florida Department of Agriculture and Consumer Services (FDACS). The main points:

• Training first. You submit a certificate from the Green Industries Best Management Practices training, which FDACS describes as six hours (FDACS). With that state certification, you are not subject to additional local testing (s. 403.9338).
• Four years. The certification expires 4 years after it is issued. To renew, you need 4 classroom hours of continuing education, at least 2 of them on fertilizer best management practices.
• Each person. It does not allow uncertified workers to apply fertilizer under your supervision.
• Fertilizer only. It does not authorize applying pesticides to turf or ornamentals, including weed-and-feed type pesticide-fertilizer mixes, or running a pest control business.

One exemption: yard workers who fertilize only individual residential properties, using fertilizer and equipment provided by the owner or resident, do not need the certification.

The Miami-Dade fertilizer ordinance

Miami-Dade adopted its Florida-friendly fertilizer ordinance (Chapter 18C of the county code) in April 2021 to protect canals, lakes and Biscayne Bay. It applies throughout the county, including inside cities, and some cities add their own rules (Miami-Dade County). Key rules for commercial applicators:

• Summer ban: no fertilizer containing nitrogen or phosphorus from May 15 through October 31.
• Fertilizer-free zones: none within 20 feet of a water body, storm drain, Biscayne Bay, wetlands or the top of a seawall.
• Phosphorus only when a soil test shows a deficiency.
• Weather and new sod: no nitrogen or phosphorus during severe weather advisories, when more than 2 inches of rain in 24 hours is forecast, or in the first 60 days after seeding or sodding.
• On the job: use deflector shields near pavement and water, keep clippings off sidewalks, streets and drains, and carry proof of your FDACS certification while applying.
• Rates: the ordinance limits how much nitrogen you can apply per application and per year, and sets a slow-release share for granular products. Check the county page for the numbers.

The business tax receipt connection

The county also ties the training to your paperwork. To obtain or renew a Miami-Dade Local Business Tax Receipt in a category that may apply fertilizer, you must show the Green Industries BMP training certificate.
