Growing Tomatoes

Growing tomatoes can be a tricky endeavor in the Sierra Nevada foothills. We have a mediterranean climate with long, hot days without rainfall in the summer. But we also have varying elevation and microclimates which can affect frost, wind, and other factors affecting tomatoes. 

The UC Master Gardeners of Mariposa County are in the process of conducting tomato trials to evaluate which varieties grow best in our central Sierra foothill county. We will provide more details as they become available.
