Arizona Master Gardener Program

The Arizona Master Gardener Program, operated by the University of Arizona Cooperative Extension, empowers highly trained volunteers to transform Arizona communities through sustainable gardening practices and horticultural expertise. With programs spanning multiple counties including Pima, Yavapai, Mohave, Coconino, Yuma, and La Paz, this organization connects passionate gardeners with comprehensive training in native plants, pollinator support, and resilient home garden design. Master Gardeners share evidence-based knowledge from over 100 years of Extension research to help residents grow food, support local ecosystems, and create thriving landscapes adapted to Arizona's unique environment. By volunteering with the program, community members gain access to expert guidance, educational resources, and hands-on opportunities to make a direct impact on local food security and environmental sustainability.
