Anyone with an interest in environmentally responsible landscaping and gardening in the low desert AND a desire to teach those principles and skills in their community from research-based materials is a candidate for the Master Gardener program.
Acceptance into the Course
There are routinely more qualified applicants for the program than available positions. Many successful applicants have applied more than once.
- Selection is not based on your application date, but rather a demonstrated willingness to volunteer in the community.
- Agreement to uphold the program mission, its policies, and participation in the University of Arizona's Designated Campus Colleague (DCC) system are all required for acceptance into the program.
Asynchronous Course Format:
Using University of Arizona’s education resources, the Master Gardener Training Course is delivered through Desire 2 Learn, an online classroom.
- Students engage in the online training portion from their home at a time that is convenient for them during the week.
- A weekly live Zoom meeting will provide opportunity for questions and personal interaction. Trainees will be organized into small groups of 6-9 people to create meaningful online interaction preparing them for volunteering in their community.
