About this episode

David Eissenstat discusses the continuous growth and regeneration of grapevine roots and its implications for vineyard management.

Many winegrape growers don't realize that grapevine roots are constantly growing, dying, and regenerating throughout the season. In this episode, David Eissenstat, Professor Emeritus at Penn State University , explains how decades of root research have challenged the myth that roots only grow at bloom and after harvest. He shares how underground research techniques reveal the hidden life of grapevine roots, why young roots drive water and nutrient uptake, how root growth changes with temperature and moisture, and what growers should know about managing vineyards with a deeper understanding of root biology.
