Louisiana has a new app homeowners can use to learn if someone claiming to be a landscape or horticulture professional has a state horticulture license or business permit.

The Louisiana Department of Agriculture and Forestry says the app also can be used to file complaints. The LDAF Business Search app is available for both Apple and Android devices.

People who do routine grass mowing and edging don't need a license, horticulture and quarantine programs director Ansel Rankins said in a news release Friday.

"However, work such as plant bed preparation, bedding plant installation, landscape design, lawn irrigation system installation, tree trimming and fertilizer application all must be conducted by someone licensed through LDAF," he said.

Licensees must pass a written exam. Arborists and landscape irrigation contractors must also have proper liability insurance. Some licensed professions require participation in periodic refresher training.

License information also remains available at the department website or by calling the Horticulture and Quarantine Programs division.
