SBI is offering a 1.5 hour Biochar Workshop this Saturday, April 21st, from 10:30 A.M. to 12 P.M, as part of the Earth Day activities at the Sonoma Garden Park.  Learn about what biochar is, how you can make it yourself or where you can purchase it locally, how to use and apply it, and why we believe all gardeners should be using it. You can help actually DO something positive about climate change just by using biochar. Come learn how!
