What the FOG?! Erosion Control

De(mist)ifying what’s happening in the vineyards around us

This vineyard is preparing to lay out straw mulch.

Have you ever noticed how Napa Valley’s hillsides rarely wear a bare patch of soil?

That’s no accident. Just as golden grasses blanket our hillsides in summer, erosion control measures protect our vineyard soils during the rainy season. Straw mulch, for example, shields bare soil from pounding raindrops, preventing the nutrient-rich topsoil from washing away. You might also spot straw wattles lining slopes—these barriers slow and disperse water, giving it time to soak into the ground while keeping sediment from traveling downhill.

When vineyards are redeveloped, Erosion Control Plans are created by expert civil engineers who understand the nuances of Napa’s terrain. These plans are then implemented by vineyard management companies or in-house farming teams who know every inch of the land. Together, they ensure the soil is protected while promoting clear, healthy watersheds.
​
These measures are not just a safeguard for today but a vital preparation for the future. As intense rainstorms become more common with shifting climate patterns, erosion control is key to keeping our soils and streams resilient. It’s just one more way we let nothing—including precious soil—slip through the fog.
