About Pima County Master Gardeners
Mission Statement
Pima County Master Gardener volunteers, directed and supported by the University of Arizona faculty and staff, educate residents by providing unbiased research-based horticulture practices and information that promote the development of healthy, sustainable communities.
Who We Are
Pima County "Master Gardeners" are university-trained volunteers who serve as community educators. We work with the University of Arizona and help expand the reach of the Cooperative Extension Master Gardener program. With the support of program staff, Master Gardeners provide research-based information on environmentally responsible gardening and landscaping to the public through various educational and outreach activities.
Plant Clinic
Our dedicated and knowledgeable volunteers are in the office Mondays and Thursdays from 10:00 am- 2:00 pm, to support your home gardening interests. We're also online, responding to questions. You can access our Plant Question Form Here. Please get in touch with the Master Gardener Plant Clinic with your home horticulture questions, and one of our amazing, University-trained, extension Master Gardener volunteers will get back to you with relevant, locally appropriate advice and resources.
If you include photos with your inquiry, please ensure your images are in focus and the plant/symptoms you want reviewed are clear and obvious, not obscured by glaring sunlight or shade. Including a ruler, pencil, or coin in your picture may be helpful for scale.

There are currently approximately 285 active University of Arizona Cooperative Extension Master Gardener Volunteers here in Pima County. Learn how you can become a Pima County Master Gardener.
One of the many functions of the Master Gardener Volunteers is to staff the Plant Clinic. They answer landscape and gardening questions over the phone or examine plant samples brought into the clinics.
Persons qualify to become Master Gardener Volunteers by completing a 60-hour training course and giving 50 hours of service to one or more approved Master Gardener Projects. The classes, which are held in Tucson at the Extension Office, 4210 N. Campbell, are specifically designed to train people to be University of Arizona Cooperative Extension Volunteers. This is not just a gardening class.
Following the course, graduates enter an intern period for up to one year, during which they provide the initial minimum of 50 hours of volunteer service. When the internship has been completed, the intern receives full Master Gardener Volunteer status.
To maintain Master Gardener Volunteer status each year after that, a volunteer must participate in at least 50 hours of approved service activities and complete 10 hours of continuing training annually.
Master Gardener Volunteers also present landscape and gardening classes throughout the city. Master Gardener Extension Volunteers are guest speakers and lead various gardening-related educational programs.
