About this listen

 What if you could hang out with experienced grape growers, ask them about the science of grape growing, vineyard operations, and more; then take an insight or two to improve your vineyard and ultimately the quality of the wines you produce? That’s what we do each week on the Vineyard Underground. Hosted by Fritz Westover –– viticulture expert more than 20 years of experience in the vineyard industry –– every episode is an in-depth look at grape growing methods, care, and even complicated matters of fertilization and pest and disease management? The goal is to provide you with an understanding of the complicated aspects of viticulture science so that experienced and even first-time grape growers will be able to understand and implement new practices in their vineyard.2022 Art Cooking Food & Wine

    070: Alternative Canopy Management Practices
    Apr 29 2025

    There are three alternative canopy management practices that generate a lot of questions and sometimes confusion from growers. So, in today’s solo episode I will cover these three canopy management practices - extreme leaf removal, shoot tipping, and palissage. I’ll go over each of these practices and discuss when they should be used to benefit your vineyard and in what instances these practices should be avoided.

    In this episode, you will hear:

    • The potential outcomes of extreme leaf removal

    • The impact of extreme leaf removal on grapevine physiology and disease prevention

    • Creative applications of shoot tipping or hedging

    • The palissage method as an alternative to traditional shoot hedging

    • New approaches surrounding the palissage method
