2020 Master Gardener Class Assignments and Notes


County, state, and federal tax dollars and donations do not fully cover the true costs of offering this program. Consequently, we must charge a program fee of $220. Accepted applicants will receive an email giving instructions on how to use our secure payment portal. PLEASE DO NOT SEND MONEY BEFORE RECEIVING THESE INSTRUCTIONS.

The Master Gardener Volunteers program is a statewide program and is one of the most popular and valued programs offered by the University of Maine Cooperative Extension. This program is committed to offering high-quality horticultural education to all interested Maine residents. To help us meet this goal and to keep the program affordable, the program relies on tax dollars, donations, and program fees.

Limited financial assistance is available. Contact Kate Garland, email for more information.

Background Check for New Master Gardener Volunteers

It is the University of Maine’s policy to conduct a background check on those who have direct responsibility for the care, safety, and security of community members or property and the care, safety, and security of minors (under 18), the elderly, incapacitated persons, or persons with developmental disabilities who participate in University-sponsored programs. Master Gardener projects are diverse in scope and there are many occasions where Master Gardeners do take on this level of responsibility. It is for that reason we conduct background checks on all volunteers.

All prospective Master Gardener Volunteers are required to complete a background check. If you are accepted into the program, Extension staff will provide you with the necessary paperwork for the background check. The Human Resources Department handles the background check process and staff does not receive a copy of the results.

Please be aware that any issues arising from the background check will not necessarily preclude you from participation in the program or being unable to volunteer, but it may impact which projects you are ultimately matched with. The University of Maine is committed to providing a safe environment for teaching, learning, and community outreach.

Training Materials

The online Master Gardener Volunteers Manual is a collection of bulletins, chapters, and links that have been carefully selected to provide you with timely, in-depth, and applied information on a number of important horticultural topics. This format will allow you to access new and updated materials long after your training. Please contact Kate Garland if you have any concerns regarding your ability to access the online manual for the training.
