Holly Sauer's February talk on propagating plants of all sorts is now available on our YouTube channel. And we want to alert you to Monika Witte's timely "How to Grow Sweet Potatoes" short talk—about 25 minutes. Why timely? Now is when you should be picking up organic sweet potatoes, and setting up to propagate starts. These two go together nicely!

Announcing Free Spanish Growing Gardeners Course (Classes in Zoom)

We're excited to announce our upcoming pilot Spanish Growing Gardeners training for beginning gardeners. We've translated this popular 12-hour training, and plan to run it in four sessions on Saturdays, each one being three hours. We begin on February 20, through March 13, 2021.

We will be presenting this training for residents of Contra Costa County for households whose primary language is Spanish, and who are interested in this beginning gardening course. See our Spanish Growing Gardeners web page for more information on and how to sign up.



Our "Soil in Your Home Garden" webinar is now on our YouTube channel—edited to be more user friendly (1:09 hr). (While you're there, subscribe so you get notifications when we post new videos!) 

Join Mike Corby and John Fike to learn about the soil in your garden—and the teeming universe under your feet. The life in that soil is essential to the health of your plants. Mike and John debunk some commonly held beliefs about soil care, and share their knowledge of soil fundamentals and ways to build soil health. Experience a more successful garden by knowing how to properly care for your soil.

From Frank McPherson, Bay Area County UCCE Director

UC Master Gardeners are University of California Cooperative Extension (UCCE) trained volunteers. They are residents of our community who give back all year to provide UCCE researched-based horticultural information to people in their communities and throughout the state. They give talks and demonstrations, conduct plant clinics, staff phone help lines, provide training at community gardens, support school garden programs, staff information tables at Farmers Markets, fairs and nurseries, and more.
