CPH Code

The MNLGA created the Maryland Certified Professional Horticulturalist Program in order to raise the standards of professionalism and education within the State’s Green Industry.  We ask our CPHers to be mindful of their interactions amongst their peers and in the community. 

Following is recommended guidance for industry professionals: 

          To regard the nursery business as an honorable and necessary profession, and to conduct                myself and my business in such a manner as to enhance the standing of my vocation in its              public acceptance.

          To deal fairly and justly with my customers and to condemn all forms of practices which                tend to discredit the nursery industry or injure its public relations

          To strive constantly and assiduously to improve my qualifications and proficiency in the                industry and thereby merit the approbation and esteem of others.
