Overview

What really sets Master Gardeners apart from other home gardeners is their special training in horticulture. In exchange for their training, persons who become Master Gardeners contribute time as volunteers, working through their Extension office to provide horticultural-related information to their communities. The type of service done by Master Gardeners varies according to community needs, and the abilities and interests of the Master Gardeners. They are representatives of the University of Arizona Cooperative Extension. In all volunteer work related to the program, Master Gardeners follow the research-based recommendations of the UA Cooperative Extension.

Applicants of the Master Gardener Program should want to learn more about gardening in the high desert, enjoy meeting others with similar gardening interests, enjoy sharing knowledge with others in your community, and have time to meet the requirements in volunteer and continuing education. Submitted applications must be received in the Cooperative Extension Office, U of A Sierra Vista by Monday, January 27, 2025. A maximum of 28 applicants can be accepted due to space limitations and are considered in the order they are received. 

Required steps

To become a Master Gardener in Cochise County you must complete the formal Master Gardener training in Cochise County, and then complete 50 volunteer hours within 12 months of graduation to become certified. After that, there is an annual requirement of 25 volunteer hours and 12 continuing education hours per fiscal year to remain certified.  Don't let the 50 hours scare you!  It's amazing how quickly you can accumulate 50 hours by engaging in various activities. Many students almost complete their 50 hours before the class series is even finished.  Plus, our students say they learn almost as much volunteering as they did during class time!

Course content

Course content includes current science-based information on topics such as basic botany, soils, plant nutrition/fertilization, planting techniques, pruning, water use & irrigation, vegetables, fruit tree care, ornamental trees and shrubs, native & desert-adapted plants, insects, integrated pest management, plant diseases, pesticide safety, and basic landscape concept discussion.

There are two levels of the Master Gardener Class, each with a different cost and benefits.

  • Level A is $175.00 which includes a textbook, a commitment for 50 hours of community volunteer work, and a shirt and name badge once the 50 hours are completed and certification is awarded.
  • Level B is $275.00 which includes the textbook only ... no volunteer hours are required, and no shirt or badge is issued.  The course fee is a cost recovery fee and covers the cost of a University-produced textbook and the projected costs of materials.

Volunteer requirements

Our history

What really sets Master Gardeners apart from other home gardeners is their special training in horticulture. In exchange for their training, persons who become Master Gardeners contribute time as volunteers, working through their Extension office to provide horticultural-related information to their communities. The type of service done by Master Gardeners varies according to community needs, and the abilities and interests of the Master Gardeners.

The Master Gardener Program began in King and Pierce Counties of Washington State in 1972 by Dr. David Gibby, an exhausted county Horticultural Extension Agent, who realized that he could multiply his resources by training amateur gardeners, who in return, would help answer the overwhelming questions that came into his office.

The program became a huge success, and today there are Master Gardener Programs in all fifty states, the District of Columbia, and three Canadian Provinces.  Cochise County Extension Agent Dr. Deborah Young started the Cochise County program in 1987.
