Master Gardener of Tuolumne Training

Master Gardener Training - Tuolumne County

Residents of both Calaveras and Tuolumne counties are invited to join the next class of Master Gardeners.  

The University of California Cooperative Extension (UCCE) invites adults interested in helping others learn about gardening and landscaping to apply to train as a Master Gardener volunteer. UCCE Master Gardener volunteers learn University-based scientific information and then share that knowledge with the gardening community. Master Gardener volunteers are people of all ages and from all walks of life with a common desire to help others learn about gardening and landscaping.

Master Gardener membership is open to anyone in Calaveras and Tuolumne counties. A background check including fingerprinting is required to become a Master Gardener.

Master Gardener training classes will include over 50 hours of intensive training by University of California personnel and horticulture specialists in various fields.  Topics include water management, soils, composting, native plants, fruit production, plant diseases, entomology, Integrated Pest Management, understanding pesticides, and more.

There is a training fee of $195 to cover costs for textbooks, reference books, class handouts and hands-on material. Class instruction, demonstrations and hands-on activities are free to those who commit to the volunteer obligation. Business owners, commercial landscape contractors, and individuals are welcome to complete the training, without volunteer obligation, for $350.

Who Can Apply?

  • Any resident of Tuolumne or Calaveras County. Most communication will be by email and through websites. You do not need internet access to be a Master Gardener, but you do need to be comfortable using a computer for research while working in the Master Gardener Office. Anyone interested in becoming a Master Gardener should attend the Orientation to learn about the Master Gardener Program and the volunteer requirements.
