The Master Gardener program trains people to assist home gardeners throughout the state with horticulture, conservation and homeowner questions. Master Gardeners may work at the UNH Cooperative Extension Infoline in Goffstown, answering questions by phone or online. A wide range of resources and support staff are available through the Infoline. Master Gardeners also provide education and assist with projects in their communities, including establishing school and community gardens. Master Gardeners may also participate in the Master Gardener Speakers Bureau and deliver presentations for community groups and organizations covering a variety of topics, such as seed-starting, composting and pest management in the garden.

The in-class training covers many topics, including botany, insects, invasive species, vegetable gardening, growing fruit, irrigation and tree identification; all topics of interest to homeowners throughout New Hampshire. Each participant has access to the Master Gardener online manual. Experts from around the state, including UNH Cooperative Extension Field Specialists, serve as instructors for the class. The class includes several field trips related to subjects such as tree and shrub identification, tree planting and pruning.

Nancy Johnson recently completed the fall 2017 training session. She says, “People in my class were from all walks of life, including a pilot, a fly-fishing guide, a retail employee and a semi-retired college professor. The one thing we all had in common was the desire to give back to our communities. Our interests and skills in gardening varied from planting a square-foot vegetable garden to establishing a small organic farm.”
