A topic that many growers consider but few understand is mothballing a vineyard. In this episode, Fritz covers it all with Dr. Christopher Chen, Integrated Vineyard Systems Advisor with the University of California Cooperative Extension. With economic pressures, market shifts, and operational challenges affecting vineyard owners across the industry, temporarily idling a vineyard can feel like a practical option — but it comes with important agronomic, legal, and financial considerations.

Dr. Chen brings a research-based, boots-on-the-ground perspective to the conversation, helping listeners understand what "mothballing" actually means in a vineyard context. Rather than a simple shutdown, he explains that mothballing requires intentional planning to preserve vine health, soil integrity, and long-term viability. Real-world questions growers are asking get answered, such as when mothballing makes sense, how long a vineyard can remain idle, and what minimum maintenance is required to avoid costly problems down the line.

Dr. Chen also highlights common mistakes growers make when they cut corners too aggressively, and how those decisions can significantly increase restart costs later. Listeners will walk away with a clearer framework for evaluating whether mothballing is the right strategy for their operation, along with guidance on how to do it responsibly if they choose that path.

In this episode, you will hear:

• What "mothballing" a vineyard really involves

• Situations where mothballing may make economic sense

• Minimum maintenance practices to protect vine health

• Risks related to pests, disease, and vineyard infrastructure

• How mothballing decisions impact future restart costs
