Master Gardener Program FAQs

What is the Master Gardener program?

The Master Gardener Program was first started by Cooperative Extension in the State of Washington in 1972 and has been operating in northern Nevada since 1974. It grew out of a need to meet an enormous increase in requests from home gardeners for horticultural information.

Master Gardeners are volunteers who have been trained in the finer points of gardening to improve their own knowledge and to share it with others. Master Gardeners provide free, research-based horticulture information to Nevadans. As volunteers, Master Gardeners contribute 35 hours per year in a variety of projects, including answering telephone inquiries, conducting plant clinics, performing soil tests, staffing booths at fairs and home shows and consulting at school and community gardens.

Why should I become a Master Gardener volunteer?

Around the country, Master Gardeners have become a vital part of Cooperative Extension’s ability to provide consumers with up-to-date, reliable information. Master Gardening has also become a fun and useful volunteer activity, which has given its participants a sense of community spirit, accomplishment and intellectual stimulation. Master Gardeners are committed to improving themselves, their community and their environment by participating in horticulture educational activities.  They are leaders in environmental stewardship.
