Master Gardener Program Mission Statement

UCCE Master Gardeners are trained volunteers who provide unbiased information to the public. Areas of expertise include drought-resistant sustainable landscapes and food production in home, community and school gardens.   Contact the Master Gardener helpline at: mgsanbern@ucanr.edu or on their phone helpline at (909)387-2182.   Want to become a Master Gardener?  Our next class will be on Saturday mornings in Montclair from January, 2019  through May, 2019.  You may apply on this website starting in July.  If you live in the mountains or high desert you may take the hybrid class that requires you to watch weekly class videos and attend two half-day classes in the mountains or desert.  All trainees must pass an open book midterm and final and present a class project in addition to volunteering at least 50 hours annually to maintain their volunteer status.  Questions?
