How To Become A Master Gardener

University of California Cooperative Extension (UCCE) Master Gardeners are volunteers who extend research-based knowledge and information on home horticulture, pest management, and sustainable landscape practices to the residents of California.  In Orange County the next volunteer training class will start in November 2023 and finish in May 2024.




What do UCCE Master Gardeners do?

University of California Cooperative Extension Master Gardeners are volunteers trained to help residents of Orange County become better gardeners. Using a variety of activities such as workshops, lectures, and a garden hotline, these volunteers answer questions about home horticulture, sustainable landscaping, and integrated pest management using University of California research-based information.

After their training Master Gardeners are qualified to help the public with problems in areas such as:

  • Food gardening
  • Growing annuals, perennials and woody ornamental plants
  • Selecting and caring for fruit and landscape trees
  • Integrated Pest Management (insect and pest control)
  • Soils, fertilizers and irrigation
  • Plant pathology
  • Composting and vermiculture
  • Weed control
  • Plant problem diagnosis
  • Water quality and conservation

Master Gardeners work in their community by volunteering for activities and projects such as:

  • Teaching workshops, or lecturing on gardening practices
  • Answering gardeners’ questions via email through our Gardening Hotline
  • Using mass media to disseminate gardening information
  • Speaking to the public on horticultural/gardening topics
  • Staffing information booths at various venues
  • Participating in research activities with academics within UC
  • Designing, planting and maintaining demonstration gardens
  • Consulting with gardeners with the goal of improving their landscape practices
  • Educating and guiding parents and teachers in gardening practices in support of school gardens

Who are Master Gardener candidates?
