However, the NYBG School of Professional Horticulture does offer a full-time, two year diploma program. Please visit the SOPH website for detailed information.

The NYBG Certificate Programs

  1. A Certificate signifies that a student has successfully fulfilled all the requirements of a prescribed series of courses. Several Certificates offer students a choice among areas of concentration.

    The Garden offers Certificates in Botanical Art and Illustration, Floral Design, Horticulture, Botany, Gardening, Therapeutic Horticulture, and Landscape Design. Certificates are awarded each spring and have been used by many recipients to investigate plant-related pursuits or to qualify for salary increases and/or increased responsibilities in their current positions.

    Please note: You have six (6) years to complete a Certificate. The catalog from which you start your Certificate program contains the requirements you must fulfill for the completion of your Certificate. See each section for the Certificate requirements.

  2. Students generally complete our Certificate Programs in 1 to 2 years. However, you are free to complete the requirements at your own pace and credits do not expire for a full six years, from the start date of your first Certificate class. Certificate requirements are based on the program of courses stated in the catalog from which you started. You can accelerate your Certificate program through Summer Intensives.

  3. Yes, Summer Intensives allow you to take multiple required Certificate classes in a condensed period of time. Summer Intensive programs are offered in Floral Design, Landscape Design, Gardening, Botanical Art and Illustration, and Therapeutic Horticulture.

    Can I enroll for more than one NYBG Certificate at a time?

    You may register for as many classes and Certificate Programs as you wish as long as you have completed the prerequisites, if any are required.

    Can I take an NYBG Certificate class without doing the entire program?

    Yes! You may are welcome to register for any course that does not have a prerequisite, including those labeled “Certificate Requirement” or “Elective”. You may also register for classes that require a prerequisite, as long as you have completed the prerequisite(s) required. You do not have to be working toward a Certificate to register for Certificate-level courses.

    Can I get an exemption from prerequisite classes?

    In rare cases, students may qualify for exemptions based on:

    • College courses from an accredited college or university
    • Evaluated non-collegiate sponsored instruction
    • or proficiency exams.

    Note: if you are exempt from a course, you must make up the hours through elective classes.

    Can I get help with an internship placement?

    The NYBG Continuing Education Department has relationships with multiple institutions and companies in the New York metro area that have accepted NYBG students as interns in the past. NYBG instructors are working professionals in their field and may also be able to assist with internship connections. Contact the registration office at 718.817.8720 for further assistance.

    What do I need to do when I’m ready to graduate?

    Students who expect to complete their Certificate requirements by June must inform the Registration Office in writing of their candidacy. Contact the Registration Office at 718.817.8720 for further assistance.

  1. “Blended” means that class sessions will take place online and in-person. The in-person portion takes place at NYBG or an off-site location.

  3. The current capacity for blended classes is 15-20 students.

Online Classes

  1. Online classes offered through NYBG Continuing Education are taught by professional instructors through Zoom — the video & audio communication platform. We use Zoom because it allows for the interactivity between instructors and students that we believe is important for authentic learning. We also continue to have small class sizes to facilitate active engagement.

  2. All classes are held in Eastern Time (ET).

  3. For accommodation requests related to a disability, questions, comments, or more information about the accessibility of Continuing Education programming, please contact us by emailing

    All other requirements vary based on the class. Requirements and materials are outlined on the course description pages of our website.
