The Master Gardener program is a volunteer organization associated with the University of California Cooperative Extension.  Our mission is to extend research based knowledge on home horticulture, pest management, and sustainable landscape practices to the residents of California and to be guided by
our core values and strategic initiatives.

Master Gardener volunteers:
  • are trained, non-paid teaching staff certified to extend practical horticultural information to Napa County residents.
  • receive an intensive 88-hour training program over a 3-month period to become certified. Instruction provides a practical course in plant science and horticulture.
  • stay up-to-date on current UC research gardening information through continuing education provided by the UC Cooperative Extension.
