The role of the Master Gardener

Picture of people around plants

Master Gardeners provide free, research-based horticulture information to Nevadans. They are volunteers who learn advanced plant science skills from at least 50 hours of classroom instruction by University of Nevada Cooperative Extension (UNCE) professionals. After training, Master Gardeners volunteer a minimum of at least 50 hours a year to pass along their newly acquired knowledge through the media, talks and workshops. They answer phone calls, send out informational materials and develop community gardens.

Master Gardeners provide a valuable service to the community by helping Cooperative Extension meet this demand for information. For more information about becoming a Master Gardener in the Carson City and Storey, Douglas and Washoe counties, please contact:

Training to become a Master Gardener

In order to become a Master Gardener, you must complete the entire training program. Classes are offered weekday mornings during even-numbered years and on weekday afternoons during odd-numbered years.

Classes are held in the early spring each year. "Live" classes are held in Cooperative Extension's Reno office at 4955 Energy Way but are video-conferenced to Extension offices in Douglas County and other Northern Nevada Areas. For information on when these classes begin, contact Ashley Andrews at 775-336-0231 or email A fee of $195 covers all program costs and study materials, including the Master Gardener Handbook. A one-time, mandatory orientation session is usually held about a month before classes begin.

Each class is three hours long and is typically held on Monday and Tuesday each week from early March to early May. The classes cover botany, plant care, soil management, plant identification, pruning, insects, plant diseases, turf management, fruit trees, vegetables, water-efficient landscaping, container gardening, weeds and plant problem diagnosis. The program is taught by Cooperative Extension employees, Nevada Department of Agriculture specialists and highly skilled local professionals.

Persons who need special accommodations for these classes should call either Wendy Hanson Mazet or Ashley Andrews at 775-784-4848 at least three days prior to a scheduled class or event.

The University of Nevada Cooperative Extension Washoe County and Douglas County Master Gardener Volunteer programs will not be holding our annual Extension Master Gardener Certification classes in 2016.

We are taking this time to make positive changes to update our Master Gardener Volunteer certification classes and to strengthen the existing program. In addition, we are diligently working to create a new statewide online Master Gardener Training program with continued educational components for existing Master Gardener volunteers.

It is important that we have the program support and curriculum resources needed to provide a great experience for our all of our existing and potential volunteers. Please be patient as we take this time to revamp the classes and program to ensure the new volunteers of the 2017 have the best experience possible.
