from Sustainable Winegrowing · host Sustainable Winegrowing - Vineyard Team

Originally developed to combat phylloxera, rootstocks are now being researched as a solution to one of viticulture's challenges: drought. Dr. Suraj Kar, Assistant Professor of Viticulture at Cal Poly San Luis Obispo, explores the 150-year history of rootstocks and their evolving purpose. He explains the complex influence rootstocks have on drought tolerance, vine vigor, and fruit set—and how long-term research is identifying those best suited to support vine longevity in a changing climate.
