How do I become a Maricopa County Master Gardener?

Classes are taught by University of Arizona Cooperative Extension faculty, industry professionals and other horticulture experts. The program teaches the fundamentals of selecting, installing, and maintaining healthy, appropriate landscapes and gardens for the Arizona low desert. The cost of the 17-week training is $275.00, which includes a thumb drive of electronic horticulture publications, a training manual, a Master Gardener badge, an insignia polo shirt, and all handouts.   Topics include:

  • Botany
  • Plant Problem Diagnosis
  • Soils
  • Ornamentals
  • Pest Management
  • Fruits
  • Vegetables and Herbs
  • Plant Propagation
  • Turf
  • Desert-Adapted Landscape Plants
  • Cacti and Succulents
  • Composting
  • Landscape Design

Training sessions are scheduled in different locations of the Valley on a rotational basis. Classes meet once a week for a three-hour session for 17 consecutive weeks. We typically hold two training sessions a year, one running from January to May (spring) and the other from July to November (summer). Please check back for updated class announcements.

To become a Certified Master Gardener, participants must complete the initial training class and donate 20 hours of volunteer service within the duration of the training. There are a wide variety of service opportunities available ranging from answering gardening questions from the public, to planning public events, to working with school gardens. To remain a Certified Master Gardener after the first year, a donation of 25 hours of volunteer service and 12 hours of continuing education is required.
