eXtension Campus

eXtension Campus is an online campus that provides objective research-based information and learning opportunities that help people improve their lives.  Campus hosts live webinars and online courses in many topics including Yard and Garden.  Many of these events are appropriate for UC Master Gardener volunteers seeking continuing education hours. 

Due to COVID-19 and the safety of our communities a statewide order of sheltering-in-place for California has made it necessary to cancel and or postpone all in person training classes.  The statewide UC Master Gardener Program office has established and will be managing a course on eXtension campus.  This course is functioning as a repository for UC Master Gardener related training that volunteers can view remotely.  Recordings, online resources and quizzes, for volunteers will be posted in the course as they become available during this time of transition. Access to this is FREE and open to the public.
