Master Gardener Program


CCE-NC Master Gardener Volunteer (MGV) Training Program Applicants;

On behalf of the entire Cornell Cooperative Extension of Nassau County (CCE-NC) Association, due to the COVID-19 pandemic I regret to inform you that we have decided to postpone our Fall 2020 MGV Training Program.  CCE-NC will retain all of your applications and will be in touch once we formulate plans for the MGV Training Program in the future.

In the meantime we plan to offer a Fall 2020 Gardening School Program. We will post details on our CCE-NC website and send you an email once it is arranged. Please check the CCE-NC website for continuing updates on educational programming and information on local events-actual and virtual.

Mary Callanan,, MGV Program Coordinator will continue to serve as the contact person for the MGV Training Program and will be reaching out to you soon with further details. Also, feel free to contact her directly if you have any other questions.

Thank you for your interest in our CCE-NC MGV Fall 2020 Training Program and continued on-going support of CCE-NC.

All my best, stay safe & healthy,

Greg Sandor

The Master Gardener program is a volunteer program developed by the Cooperative Extension System and coordinated by county units of the system. It is a program designed to both expand the educational level of volunteers with accurate, unbiased horticultural information and to provide the volunteers with an opportunity to share this information with others. The term "Master Gardener" has become synonymous with a knowledgeable individual, provided with in-depth horticultural training, working to enhance their community and share their knowledge with others.

To prepare Master Gardeners for their role in the community, Cornell Cooperative Extension of Nassau County provides an in-depth training program. Staff from Cornell Cooperative Extension, Cornell University faculty and local horticulturists serve as the training team for the program. Resource materials, fact sheets, bulletins and visual aides are provided to each Master Gardener as resources for their work.

The goal of the Master Gardener Training Program is two-fold:

  • To educate home gardeners in practical, environmentally friendly horticulture methods and related topics
  • To train class members to be multipliers of information to the public through our Horticulture Information Center by staffing the phones, giving lectures, answering questions at plant clinics, etc.

In general, classes are held every week for a period of 15 weeks. In addition, several field trips are scheduled during the early period of training. Master Gardener training includes in-depth lectures, field training, Horticulture Information Center orientation and training, hands-on pruning, soil testing, composting, IPM (Integrated Pest Management), etc. Homework, weekly quizzes and reading assignments are required.

Upon completion of formal training, Master Gardener Interns have an obligation to return one hundred fifty (150) hours of volunteer service in a variety of mutually agreed upon programs and activities of Cornell Cooperative Extension. Continued learning after graduation via regularly scheduled in-service training opportunities is recommended.

There are over 100 active Master Gardeners in Nassau County.  Volunteer hours were spent in the Horticulture Information Center manning the gardening helpline, performing soil tests and answering questions from residents who visited the Center. Also, hours were spent maintaining demonstration gardens and demonstration sites, giving presentations to community groups, attending in-service programs, and manning exhibits and information booths at various community locations.
