A master gardener open garden day will be Sept. 11 at the University of California Cooperative Extension master gardener garden on the campus of Cassina High School, 251 S. Barretta St. in Sonora.
The topic for the month of September is trees -- how to plant them, how to stake them, how to train them and how to prune for fire safety. A handout on garden mistakes will be available. The garden opens at 10 a.m. for wandering and conversation with master gardeners. Free public demonstrations begin at 10:30 a.m.
For more information, call (209) 533-5696.
