Master Gardener volunteers help extend gardening knowledge into the community.

Master Gardener Volunteers

What is the Master Gardener Program?

The Master Gardener Program is a national program of trained volunteers who work in partnership with their county Cooperative Extension office to extend information throughout the community. The first Master Gardener program was started in Washington State in 1972. Forty-six states now have Master Gardener programs. For information on Master Gardeners within NYS visit the New York State Master Gardener Program website. CCE’s Master Gardener Volunteer program is an integral part of educational programs for home, school, and community gardeners at all levels of expertise.

Master Gardener Volunteer Training begins January 11, 2025

  • Applications are NO LONGER BEING ACCEPTED for 2024.  
  • You may submit an application for the 2025 training. 

We are accepting applications for the next Master Gardener training class for 2025.

The 2025 Master Gardener training will include a combination of online materials in conjunction with in-person classes. The online work will be done on your own time.  Classes include; reading selected educational material, watching lectures, module knowledge checks, and completing a final project. Trainees will be expected to complete all online assignments in accordance with the program.

  • Topics include basic horticulture, soil science, composting, botany, insect biology, plant diseases, Integrated Pest Management (IPM), wildlife management as well as best practices in cultivating vegetables, herbs, houseplants, trees, and shrubs.

In-person classes will be held tentatively on four Saturdays, in the spring of 2025. Virtual meetings will be held evenings, tentatively every other week, Wednesday evenings from 6:30 pm to 8:30 pm.  These virtual meetings will include some lectures, but also will include hands-on activities to reinforce the topics covered in the online portion of the course. They will also allow trainees to get to know each other better and meet other active Master Gardener volunteers. The specific schedule dates and content will be finalized in the fall of 2024.

The training expands beyond horticulture content to include skill development in communication, community leadership, peer education, and working with specific audiences such as children and youth or older adults.

Two emergency/medical absences are allowed, but the MG Coordinator must be informed in advance of absence.

Who becomes a Master Gardener?

Master Gardeners enjoy people and plants. They usually have no professional gardening or landscaping experience, only a genuine interest in sharing their knowledge, and sufficient free time to volunteer in Master Gardener activities.

How do I become a Master Gardener?

  1. Master Gardener TRAINEES receive instruction in plant nutrition, soils, vegetables, trees, shrubs and lawns, diseases and insects that affect plants, pruning, and much more. 
  2. After this instruction, trainees complete a final project and become Master Gardener APPRENTICES.  
  3. After completion of 200 hours of service as an apprentice, volunteers become  CERTIFIED MASTER GARDENERS Certified Master Gardeners

Advanced instruction is offered, and special seminars and workshops are held so that Master Gardeners are kept current on gardening information and methods.
