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.
Gramegna Power Harrow
Pros: Lower soil compaction than others. Effective in varying soil types. Can handle terraces. Head articulates to adjust for slope.
Cons: Single-sided, doesn’t do well with lots of rocks. Expensive and lots of maintenance required.
Calderoni Rotary Disk Harrow
Pros: Double-sided and efficient. Handles rocks well.
Cons: More compaction, especially on moist soil.
Pellenc Sunflower
Pros: Double-sided, lower number of passes. Limited soil disturbance.
Cons: Can cause soil compaction. Can require multiple passes due to lower termination efficacy.
Gearmore Spedovator
Pros: Low soil disturbance. Can handle tall weeds.
Cons: Requires several passes: One to turn the soil/weeds and another to replace the soil on each side.
French Plow
Pros: Very effective at smothering weeds and preventing regrowth.
Cons: Significant soil disturbance (inversion of the top layer). Possible compaction in wet soil. Long term use can displace topsoil. Single-sided.
Fischer TWISTER Mower
Pros: No soil disturbance. Fast groundspeed. Keeps living roots in the ground.
Cons: Does not kill herbaceous cover. Possible understory growth depending on timing.
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.

There will be a panel with Ivo Jeramaz, Vice President of Vineyards & Production at Grgich Hills Estates and Steve Matthiasson, of Matthiasson Winery and Premiere Vit, talking about herbicide-free farming, approaches, costs/benefit and ROI.
Thursday, January 18
2:00 pm - 4:00 pm
Alpha Omega
Producers have been subjected to a rollercoaster recently- from an extremely early harvest in 2022 due to heat, to one of the latest memorable harvests in 2023 due to a cool growing season. Join us, along with industry-leading winegrowers and vintners, to discuss the 2023 season and the techniques in the vineyard and cellar that can aid in adapting to the new norm of climatic extremes.
Registration Coming Soon
Thursday, February 15, 2024 · 9am - 1:30pm
Inglenook
Learn from Inglenook and others about equipment and tools being used for herbicide-free and organic weed management. See tools in action and ask questions. Then hear from Perennial Grazing about the the benefits of sheep in the vineyard, and the essential importance of proper management. In addition, hear from Sarah Keiser with Wild Oat Hollow about the use of goats for adjacent land management and fire fuel thinning. We'll look at a forested area and talk about potential prescriptions.
Location & Time TBD
One of the main resistances to phasing out Roundup is increased labor and equipment costs. With rising supply chain costs, the costs of herbicides and fertilizers have risen dramatically, so phaseout can offset increased labor costs. In addition, leaders like Grgich Hills Estate, a Napa Green member, have shown that regenerative organic farming can be cost-effective.
Regenerative practices are a proactive approach to farm health. If you’re healthy enough you don’t get sick – you’re able to fight off pests and disease. It’s a paradigm shift.
We need to have a cultural shift in vineyard aesthetics. Is bare ground how we want to present our skill as farmers? Or cultivating life under our vines?
Regenerative farming starts with a mindset to build biological and human communities…On farm after farm the soil is naked, hungry, thirsty and running a fever.
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.
You don’t hear more stories about how farmers eliminate herbicides because usually they just decide to do it, and they don’t look back. The decision is the hardest part.
Eliminating Roundup and other synthetic herbicides is a significant step towards more just, resilient agricultural communities and local ecosystems. A non-exhaustive list of the benefits: Farmworker health, Soil health, Ecosystem health, Community health, Consumer health, Consumer perception/Market demand, Visibility of Napa Valley and the wine industry.

‘Exploring what Regenerative Farming Systems can teach us about Regenerative Social Systems.’
This is a rarely-available, full-day leadership opportunity. For anyone who joined us for our 2022 & 2023 THRIVES/RISE Climate & Wine Symposiums and heard Nikki Silvestri speak our guess is that for you, like us, 60-minutes wasn’t enough.

Congratulations to Napa Green Certified @boeschenvineyards on being featured in @pressdemo as a first to offer hazard pay and disaster insurance to seasonal agricultural workers! Read on for more and find the link in our bio to the full story..
“To Boeschen, committing to this small safety net in times of emergency isn’t just the right thing to do. It’s the way labor relations are headed in the wine business.
When vineyard crews showed up for this year’s harvest at Boeschen Vineyards, a small winery that operates largely out of a cave dug into a pretty hillside off Silverado Trail just north of St. Helena, they were asked to listen to a three-minute presentation.
Doug Boeschen, the business’ owner, informed these seasonal agricultural workers, among the most economically vulnerable in the North Bay, that the winery was now offering them a combination of hazard pay and disaster insurance.
Boeschen will provide an option to its workers — including the seasonal labor that pours into the region’s renowned vineyards for just a few days or weeks at a time. If the Air Quality Index climbs above 150, Boeschen’s workers will be able to choose between receiving time-and-a-half to remain on the job, or to take paid time off.
Boeschen will also pay its laborers if they are forced to leave a worksite under an evacuation order.”
This article also features other notable efforts on behalf of larger companies and regions working towards the same end. We highly recommend you read the full article!
Sierra is our Soil & Climate Specialist at Napa Green and her ask this year is that everyone consider donating to our small but mighty Team Green for Giving Season!
Here is more from @regenwithsierra:
“🎃 Happy Halloween Eve everyone! Today is my birthday, and I would be beyond thrilled if you would consider a donation to @napagreen to support a nonprofit focused on climate action in the wine industry 🍷🍾
@napagreen has the leading set of standards for sustainable practices, from soil to bottle. I am most proud of the work we do with winegrape growers to adopt regenerative agricultural practices in their vineyards.
Please consider supporting us in our mission! Click the link in bio for more! “
