We are committed to offering high quality horticultural education to all interested Maine residents. To help us meet this goal and keep the program affordable, the program relies on tax dollars, donations, and program fees.

County, state, and federal tax dollars and donations do not fully cover the true costs of offering this program , which is currently $220.00. Limited financial assistance is available.

We welcome donations to support Master Gardener Volunteer activities.
