Napa Green is the first sustainable winegrowing certification globally to require the phaseout of Roundup, and ultimately synthetic herbicides. When we looked for a roadmap and resources for going herbicide-free we didn’t find it all in one place, so we created this Weed Management Toolkit to support our Napa Green community and other perennial growers looking to cultivate healthier soils and regenerative farm systems.
Since Napa Green became an independent nonprofit in 2019, our goal has been to set the highest bar for sustainability and climate action in the wine industry. Our next-level Napa Green Vineyard program, launched in 2021, is unique in its whole-systems focus on: Social Justice, Regenerative Ag & Soil Health, Irrigation Efficiency, Forest Health, Climate-smart burning/alternatives, and Pesticides.
While pesticide and herbicide use is just one element of a holistic approach to sustainable winegrowing and climate action leadership, this leadership matters to our families, our communities, and our customers. As a world-renowned winegrowing region, producing the premier agricultural product, we must leverage our powerful leadership platform to galvanize change locally and globally.
Clemens Weed Knife
Pros: Lower soil disturbance, no soil inversion. High ground speed. The frame can also support a ‘twister’ type mower for a pre-knife pass, or a french plow for deeper disturbance. Single- or double-sided.
Cons: Low level of disturbance means weeds can re-sprout depending on timing and soil moisture. Not great with heavy weed cover. Can either be one sided (lower efficency) or, on flat ground, can have a second side, but might require multiple passes.
Sheep
Pros: Ability to manage the entire vineyard floor, even steep, terraced, and tight rows, without fossil fuels. Increased nutrient cycling, as well as soil and vine health.
Cons: Require knowledgeable shepherds to be managed/rotated effectively. Small parcels are inefficient. Damage to vines and infrastructure is possible.
Organic (OMRI) Herbicides
Pros: Helpful as a foliar spray when the soil is too wet to cultivate. Reduces weed competition in unfavorable conditions
Cons: Organic herbicides do not match the effectiveness of synthetic herbicides, but are another tool in the weed management kit. They are ineffective once weeds have fully established root systems and can be expensive.
Note that feedback is assembled from members who have used these tools.
The Napa Green Vineyard certification provides growers a beneficial roadmap for continual improvement. The process lead Dominus Estate to measure our environmental impact and, since we can only change what we measure, has strengthened our methods for interacting with our site's vital resources: soils, water, flora, fauna and people. Ultimately, this certification improves the grower's relationship to the land and deeply informs farming decisions.
Tod Mostero, Director of Viticulture & Winemaking at Dominus Estate
Eliminating Roundup and other synthetic herbicides is a significant step towards more just, resilient agricultural communities and local ecosystems.

🍴Wednesday April, 23rd is the day NOT to miss lunch at @cliffamily!!
Come enjoy delicious food while supporting Napa Green! See you there.
Uniquely, Napa Green isn’t just a roadmap of leading practices. Napa Green provides an expert, boots-on-the-ground consulting team that develops:
✅ Regenerative Carbon Farm Plans (to enhance soil health, biodiversity, resilience, and carbon storage)
✅ Irrigation Distribution Uniformity Assessments (to maximize water efficiency)
✅ Integrated Resource Assessments (to reduce energy, water, waste and emissions in production)
✅ Action Plans for continuing improvement (tailored to the opportunities and goals of each vineyard or winery)
Additionally, we support soil sampling and analysis, provide resource assistance, run practical training and education workshops throughout the year, and provide valuable, hands-on guidance in meeting your climate action goals.
✅ Napa Green members implement over 120 best practices in both the Vineyard and Winery. This Earth Month, learn about 21 of them with “21 Days, 21 Ways” counting down to Earth Day.

Napa Green’s vineyard team is trained to develop regenerative, whole-farm Carbon Farm Plans (CFPs). These plans review all of the current beneficial practices that are increasing soil and ecosystem health and storing carbon, and identify additional opportunities to regenerate the soil and vineyard ecosystem and simultaneously maximize carbon capture in a given property. Each vineyard’s goal is to become carbon neutral (or negative) and increase the resilience of vineyards, businesses, and our community.

Forests are not only our largest terrestrial carbon sink, they are also home to 80% of the world’s on-land diversity. We need healthy forests, which means a balanced density of native trees and plants. Healthy forests experience lower intensity fires with less tree mortality, meaning higher carbon retention and ecosystem function.

All of our members are committed to using at least 60% renewable energy, whether through on-site solar and other renewable sources or by working with @mcecleanenergy to access clean power through the grid. The impact? Over 1.2 million pounds of CO2e saved by wineries and vineyards in just one year. To put that into perspective it’s the equivalent to offsetting the emissions from driving over 1.5 million miles in a typical gas-powered car!

As part of their commitment to sustainability, Napa Green Certified Winery members collaborate with key suppliers and utilize their purchasing power to support eco-friendly practices. In the same way, we can make a difference at home by choosing materials made from post-consumer recycled materials, and selecting reusable, recyclable, compostable, biodegradable, and non-toxic products.

Napa Green Certified Vineyards implement climate-smart burn practices, such as Conservation Burning, Flame Cap Kilns, and Air Curtain Burners. These practices reduce smoke and emissions and create biochar. Biochar is re-fossilized wood that provides long-term carbon storage. Even more compelling, when inoculated and applied with compost, biochar aids in water retention and increases water and fertilizer efficiency.

Napa Green Certified Vineyards implement practices to create habitat for beneficial wildlife, including bluebirds, owls, bats, and raptors. Members may also install boxes and perches if trees or other natural perches aren’t present to encourage these animals in the vineyard. These measures are part of a broader commitment to sustainable and regenerative farming practices.

While vineyards don’t directly require pollination, pollinators still play a vital role in the overall health of our ecosystems. Increased biodiversity leads to better soil health, water retention and can attract beneficial insects. Plus, pollinators are friend shaped! 🐝

Carbon storage is inherently site-specific, tied to unique combinations of soil types, microclimates, historical farming practices, and more. Napa Green Certified Vineyards leverage soil sampling to validate the on-the-ground impacts of their regenerative farming methods.
