About Us

As a leader in horticultural education for more than 125 years, The New York Botanical Garden offers the nation’s largest plant-related continuing education program for adults. Our certificate programs are at the forefront of education, with classes designed by experts and honed to deliver the necessary skills to start a new career or rewarding personal pursuit. We also bring students in contact with internationally renowned experts through lectures and master classes offered each season. Students have access to the Garden’s unparalleled resources, including its 50 display gardens as well as the LuEsther T. Mertz Library with collections containing well over one million items. Whether you take a class just for fun or enroll in a prestigious NYBG Certificate Program, we have something for you!


  1. “Blended” means that class sessions will take place online via Zoom and in-person. The in-person portion takes place entirely outside on NYBG grounds. Blended classes are currently offered for select Botany, Urban Naturalist, and Horticulture classes. Class details and times will vary; please visit our registration website for details.

  2. We feel that it is crucial for Horticulture, Botany, and Naturalist students in particular to be able to see plants growing in order to identify them and best understand their culture, ecology, and maintenance requirements.

  3. Classes will meet outside at select areas of NYBG, rain or shine. There will be no indoor class instruction. The exact location will be determined by the instructor and communicated to students prior to the class start date.

  4. We are currently limiting blended classes to 15 students.

  5. The safety of our students, instructors, and staff remains our top priority, and as of August 3, 2021, NYBG has made the following protocol adjustments:

    • Face coverings are required indoors, at the Edible Academy, and at the Everett Children’s Adventure Garden, regardless of vaccination status. NYBG will continue to monitor CDC, state, and local guidelines. This applies to everyone at the Garden—staff, students, instructors, and visitors.
    • Our committed team of engineers continues to work diligently to maintain the heating, ventilation, and air conditioning systems throughout the Garden, and to increase ventilation with outdoor air to the greatest extent possible.
    • Our dedicated custodial team routinely cleans and sanitizes shared areas and frequently-touched surfaces.
    • As a general practice, please do not come to the Garden for class if you are not feeling well.
  6. No, you must be able to attend the in-person classes. The instruction is live and will not be recorded and PowerPoints will not be available for the in-person classes.

    An inherent risk of exposure to the coronavirus (COVID-19) exists in any public space where people are present. People visiting The New York Botanical Garden do so at their own risk as to such exposure as well as other risks inherent to outdoor public spaces. We will continue to monitor state and city guidelines to inform the Garden’s operations.

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 Adult Education programming, please contact Lisa Whitmer by emailing or calling 718.817.8765.

  4. No. Once you register for a class, you will receive a Zoom log-in link in your confirmation email. To join the class, simply click on the link provided which will open up to your internet browser.

  5. You’ll receive the Zoom log-in link a total of 3 times prior to the class start date:

    1. In your confirmation email sent after you register
    2. In an instructional email sent approximately 3 days before the class start date
    3. In a reminder email sent one day prior to the class start date
  6. If you join the class a few minutes early, you may be placed in a virtual Waiting Room until the official start time.

    If you are a few minutes late to class, the instructor will make their best effort to admit you into the class with minimal delay.

  7. Yes, you will use this same log-in link for each session of the class unless your instructor says otherwise. Please keep this link handy!

  8. All online classes require an internet connection. Class instruction will occur within the virtual classroom on Zoom where you can interact with the instructor and other students through video, audio, and/or chat functions. You can use Zoom on computers, tablets, and phones. Tablets and phones are somewhat limited in what they allow you to do, but you will still be able to see and hear the class.

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

  9. We recommend taking some time to familiarize yourself with Zoom before your class begins, so you know the basics. Please see Zoom’s Getting Started page for more information. If you still have difficulty, please email as soon as you can and we will respond as quickly as possible.

  10. Select online class sessions are recorded.

  11. Yes! Any certificate-level requirement or elective course made available online qualifies toward your certificate completion.

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 Adult 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?
