For CPH certification purposes, after the eligibility requirements have been met, the candidate need only demonstrate, to the satisfaction of the CPH Board, that the candidate knows and can apply the essentials of the nursery, landscape, and garden center industries.

      The examination questions will be based on such essentials as are included in the Training Manual.


      The Certified Professional Horticulturist (CPH) program is sponsored by the Maryland Nursery and Landscape Association. Responsibility for administering the CPH program rests with the CPH Board. The Board is comprised of four appointed members from MNLA, representing nursery, landscape, and garden center industries, one member from the University of Maryland Department of Horticulture, one member from the Maryland State Department of Agriculture, the MNLA President, and the Executive Director.

      CPH examinations are prepared, conducted, and graded by or under the direction of the CPH Certification Board.

      The Certification Board has no intention whatever to determine who shall engage in the nursery, landscape, and garden center industries. That a person is not certified does not indicate that the candidate is unqualified to engage in these industries, only that such a person has not fulfilled the requirements for CPH status or applied for the recognition.
