Every vineyard tells a story. But behind every healthy vine, balanced canopy, and successful harvest is another story: the careful planning that goes into managing land, water, labor, and natural resources. A Farm Plan is more than a regulatory requirement or a certification checklist—it’s a roadmap for resilience. It helps growers align day-to-day decisions with long-term goals while protecting both the bottom line and the environment.

A farm management plan is a dynamic, written document that outlines strategies for managing your vineyard while protecting soil health, water quality, biodiversity, and economic viability.
​It is:

• A Resource Inventory: Assessing soil, water, crops, labor, infrastructure, and the surrounding ecosystem.
• A Regulatory Tool: Documenting compliance with county and state requirements like the Waste Discharge Requirements (WDR).
• A Certification Requirement: Integral to programs such as Napa Green, Fish Friendly Farming, and the California Sustainable Winegrowing Program.
• A Future-Focused Map: A framework to adapt to climate variability, pest pressure, and evolving market and regulatory landscapes. 
  

Planting a vineyard is one of the most important—and expensive—investments a grower can make. Every decision made at the outset sets the stage for decades of vineyard health, productivity, and economic viability. At Napa Valley Grapegrowers, we believe that choosing clean plant material is a fundamental step in ensuring the long-term success of your vineyard—and protecting the resilience of the entire region.

What Is "Clean Plant Material"?
“Clean” means plant material that is tested and verified to be free of known viral pathogens and damaging pests. That includes both scion wood and rootstock. It also means the nursery has followed rigorous sanitation and propagation protocols to minimize the risk of contamination from viral, bacterial, fungal, or insect vectors.
Diseases like Grapevine Red Blotch Virus (GRBV), Grapevine Leafroll-Associated Viruses (GLRaVs), and fungal trunk pathogens continue to impact vine longevity and grape quality in California. Even vines that appear healthy can harbor pathogens—making certification and testing essential.

Why It Matters: Economics, Environment, and Equity

• Economic: Replanting due to infected vines can cost $25,000–$50,000 per acre and delay full productivity for 3+ years.
• Environmental: Replanting early wastes water, diesel, fertilizers, and soil amendments—all inputs with a carbon footprint.
• Community Impact: Lost revenue can reduce farmworker hours, disrupt contracts, and strain vineyard operations.

Clean material isn't just about vine health. It’s about building resilience into our farms, our businesses, and our shared agricultural landscape.

Abandoned or neglected vineyards are more than an eyesore—they are a serious agricultural and environmental threat to Napa Valley’s thriving winegrowing community. When left untended, these sites can become hotspots for pests and disease, putting neighboring vineyards and the region’s sustainability efforts at risk. As climate pressure, economic uncertainty, and shifting land use intensify, understanding the risks and responsibilities around vineyard neglect is more important than ever.
​
1. What Counts as an Abandoned or Neglected Vineyard?
According to California law and agricultural best practices, a vineyard may be considered abandoned or neglected if:

• Vines are not pruned or maintained, often with excessive sucker growth.
• Mummified fruit remains on the vine from prior seasons.
• Trellis, irrigation, or frost protection systems are in disrepair.
• Brush, weeds, or invasive species overtake vineyard rows or headlands.
• Erosion control has failed, particularly on hillsides or sloped land.

Note: Vineyards slated for removal may temporarily resemble abandoned sites. Be sure to communicate with neighbors and the Agricultural Commissioner if delays occur due to weather or scheduling.

Pesticide and fungicide applications play a role in integrated pest management (IPM), but when and how you spray can make all the difference—for your vines, your crew, your neighbors, and the surrounding ecosystem. With tighter regulations, climate variability, and increased community awareness, it’s critical that growers approach each spray event with intention, precision, and care.
Below is a framework for science-based, sustainable decision-making around pesticide applications. These principles help ensure each application is safe, compliant, and effective.

1. Pest Identification

• Clearly define the target pest or disease before applying anything
• Confirm whether the pest population has reached an economic threshold or poses a risk of unacceptable damage if left untreated
• Avoid prophylactic or calendar-based applications unless supported by environmental modeling (e.g., powdery mildew risk indexes)

2. Information and Professional Guidance

• Secure a licensed Pest Control Advisor (PCA) recommendation when required by law
• Review the product label and SDS (Safety Data Sheet) thoroughly, and ensure the product is registered for use on grapes and appropriate for the stage of vine growth
• Evaluate all environmental factors—temperature, humidity, wind speed, and inversion risk—to plan safe and effective application timing
• Consider whether a different time of day or weather window would minimize drift and maximize efficacy

In Napa Valley, farming is more than a livelihood—it’s a legacy. While agriculture enjoys strong protections under Napa County’s “Right to Farm” policies, the long-term sustainability of our region depends on more than laws. It depends on relationships. Vineyard practices can affect nearby homes, schools, and rural roads, which means growers play a crucial role in shaping how the public experiences agriculture.
Being a good neighbor is a core part of environmental stewardship and a reflection of the industry’s shared values. Whether you're a multigenerational grower or new to the vineyard lifestyle, here are practical ways to build trust and goodwill within your community.

1. ​Start with Connection

• Build relationships before concerns arise. Reach out to your neighbors personally—invite them to walk your vineyard, share a glass of wine, or learn about your farming practices
• Open the door to communication. Encourage neighbors to contact you directly if they have questions or concerns. A proactive conversation can often prevent misunderstandings later

2. Be Mindful of Nighttime Activities

• Provide advance notice of any nighttime work like spraying or harvesting. These activities can be disruptive, and a heads-up shows respect.
• Harvest respectfully: Position your staging areas and lighting to minimize impact—keep floodlights pointed away from homes and reduce excess noise wherever possible.
