When to Water Your Garden: Understanding Soil Moisture and VWC Made Simple
ByStephen Albert

Knowing when to water is just as important as what to plant. In vegetable gardens—especially raised beds and in-ground plots like those in Sonoma—soil moisture is best measured by Volumetric Water Content (VWC). VWC tells you the actual water available to roots, making it far more reliable than surface dryness or guesswork. By tracking VWC,…

What is VWC in the Garden and How to Measure It
ByStephen Albert

Gardeners often focus on soil moisture, but a more precise metric—Volumetric Water Content (VWC)—tells you exactly how much water is available to plant roots. Over decades of gardening in Sonoma, I’ve found that monitoring VWC can make the difference between healthy, vigorous plants and slow, stressed growth. What is VWC? Volumetric Water Content (VWC) is…
