Indiana Accredited Horticulturist Certification

What is the Indiana Accredited Horticulturist Program?

The Indiana Nursery and Landscape Association have developed the Indiana Accredited Horticulturist Program to provide a method of self-study and accreditation for individuals in the nursery industry. The goal of this certification and accreditation program is to develop knowledgeable, motivated, professional employees for the landscape nursery industry.

There are over 700 Indiana Accredited Horticulturists and over 125 Master Horticulturists. The success of the program and the upgrading of the personnel in the nursery industry are direct results of the emphasis the Indiana Nursery and Landscape Association have placed on education programs. You are encouraged to take advantage of this valued educational service of your association.
