LNLA'S CERTIFIED NURSERY AND LANDSCAPE PROFESSIONAL (CNLP)


It is important to note that the LNLA's CNLP is not the same as the state licenses needed to practice horticulture in Louisiana, and does not allow you to legally conduct a professional horticultural business in Louisiana. To learn more about the state licensing process contact the Louisiana Department of Agriculture and Forestry Horticulture Commission at 225-952-8100 and visit their website.

Why get certified?

You will increase your knowledge of horticulture and you may cite your LNLA Certication on resumes, business cards, vehicles, etc. to demonstrate your high professional standards. Certification shows that you have a good understanding of the information contained in the Manual. Horticulture businesses, such as nurseries, garden centers, landscape maintenance companies and landscape instillation companies, send their employees to the CNLP Review and Tests to make them more knowledgeable and effective.

Who should get certified?

Primarily, persons in the retail garden center and landscape contracting/maintenance areas of the ‘Green Industry’ participate, however the course is also recommended for wholesale growers, irrigation contractors and Master Gardeners. The manual review is excellent preparation for the Louisiana Department of Agriculture and Forestry’s horticultural services and landscape contracting. The CNLP was established to provide a professional educational opportunity for ‘Green Industry’ professionals.

What do I need to know to pass the exam?

The Louisiana Manual for the Environmental Horticulture Industry is the primary reference you must be familiar with to pass the test and obtain your state horticultural licenses in the categories of Horticulturist, Landscape Contractor and Nursery Stock Dealer. The Manual is thoroughly reviewed during the CNLP Review making it an excellent way to prepare for your state license tests. It is best to obtain and look through the Manual before the Review and Exams. The exam includes identification of plant specimens from the several lists of plants in various sections of the manual, so you should be able to identify many of the plants listed in the manual.

Where do I get the manual?

The cost of the Manual is $65 (includes S/H).  Click here to order the manual online.
