074: Variation in Young Vine Training in Diverse Climates

In this solo episode, we take a deep dive into the many variables that influence young vine training in different climates. Listeners will gain a clear understanding of how climate, trellis selection, rootstock vigor, and regional weather risks shape vine training strategies. Fritz explains how cold-climate growers often rely on double trunks or "spare parts viticulture" to prepare for winter damage, while warmer-climate vineyards may benefit from fast-tracking techniques like green topping and one-shoot training for quicker vineyard establishment. We walk through scenarios where single-trunk systems are ideal, when to consider double trunks, and how the practice of renewing trunks every few years can extend vine longevity. We also break down when to use green topping, how to avoid bull canes, and why mature leaves on developing trunks should never be removed.  Growers will leave this episode with specific, actionable tips to match their training approach to their unique vineyard conditions, helping them improve both short-term success and long-term vineyard health. In this episode, you will hear: Differences between trellis systems and vine training systems When and why to use single vs. double trunk strategies What "spare parts viticulture" is and where it makes sense Green topping and other fast-tracking methods explained How to manage training for high- and low-vigor vineyard sites Follow and Review: If you enjoyed this episode, be sure to follow the podcast and leave a 5-star review on Apple Podcasts!
