The services a lawn company adds to raise the ticket, weed control, fertilizer, irrigation and installation, are where licensing comes in, and each one changes what an ad, a truck or an invoice has to show. What follows is how we read the published rules in October 2026; it is not legal advice, so confirm the rules for your own license and city with counsel or the licensing agency before an ad runs. Three states show how differently it can work.
Texas licenses the irrigator and the sprayer separately. The Texas Commission on Environmental Quality licenses irrigators, and its leaflet for homeowners tells them to ignore any irrigation ad that leaves out the irrigator’s license number, something like LI0123456. Bids, invoices and warranties should carry the irrigator’s name, license number, business address and phone number, the number belongs on the vehicle, and a license holder must be on site for any installation or repair. Every Texas city of more than 20,000 people must also have its own irrigation ordinance, so local watering rules sit on top of the state license; nationally, EPA WaterSense puts outdoor residential water use at nearly 8 billion gallons a day, mainly for irrigation. Weed control is a second license: the Texas Department of Agriculture requires one to apply any pesticide, general-use products included, to lawns for hire, while applicators who spread only fertilizer need none.
Florida licenses the fertilizer. Since January 1, 2014, anyone applying commercial fertilizer to an urban landscape must hold a state certification under Florida Statutes 482.1562, and it expires four years after it is issued. A Florida fertilization program sold without it is a liability, not a service line.
California licenses the installation. Landscape installation is contracting, licensed by the CSLB under the C-27 Landscaping Contractor class, and Business and Professions Code 7030.5 puts the license number in every form of advertising. Since January 1, 2025 the minor work exemption covers jobs up to $1,000, but only when no permit is needed and the operator employs nobody on the job, and an unlicensed operator may advertise that work only with a statement that it is not licensed, as the CSLB’s 2024 bulletin on the change explains. A maintenance gardener who does occasional pest control as part of the gardening business needs a separate state license from the Department of Pesticide Regulation. The California landscaping marketing page adds turf rebates and the HOA deadlines.
What the ad has to show in the other states we cover
- Arizona asks no contractor license for mowing and pruning, but walls, patios and drip lines are licensed work, and Arizona Revised Statutes 32-1124 puts the number, with “ROC” in front, on bids and published ads. More on the Arizona landscaping marketing page.
- Colorado counts advertising as licensed activity: C.R.S. 35-10-117 means an unlicensed crew may not even offer spraying for hire in an ad. The Colorado landscaping marketing page covers drought rules and HOA boards.
- Florida counties set fertilizer blackouts of their own under Florida Statutes 403.9337, so a summer feeding offer that is legal in one county can be banned in the next. The Florida landscaping marketing page maps the dates county by county.
- Michigan reads a weed or grub control line as a claim to be a licensed applicator: under MCL 324.8313, any business presenting itself as a pesticide applicator must hold a commercial license, one per location. More on the Michigan landscaping marketing page, including the neighbor notification registry.
- Minnesota bars phosphorus fertilizer on turf under Minnesota Statutes 18C.60, with narrow exceptions such as a recent soil or tissue test showing a shortage or a new lawn going in, so a program page should say the test comes first. The Minnesota landscaping marketing page follows the season from thaw to plow.
- Nevada wants the company name and license number on every ad, and chapter 624 of its statutes counts websites and directories as ads. The Nevada landscaping marketing page covers the grass removal deadline and the water authority rebate.
Green claims follow one federal rule everywhere: the FTC’s Green Guides warn against broad “eco-friendly” or “green” claims a seller cannot back, so say what the crew actually does, such as battery equipment on a named route or drip irrigation in every bed.
Where no license applies, a credential can do the same work in an ad. The National Association of Landscape Professionals runs a Landscape Industry Certified Technician exam with five specialty areas, from turf maintenance to irrigation.
For the marketing, that means a license line in every irrigation or treatment ad where the state asks for one, the numbers on the trucks and in the site footer, and service pages that say which work is licensed and who holds the license.
