Vine Balance - Agenda and Speakers

Setting the Stage: Factors Affecting Foothill Site Capacities

Lynn Wunderlich, UCCE Central Sierra Farm Advisor
Lynn has been the UCCE Farm Advisor in the Central Sierra for 18 years, and has served the wine grape industry since 2008. During this time, Lynn has visited vineyards across the four counties and has seen the variety of site factors affecting vine growth and crop load.  Lynn will present an overview of natural resource considerations for growing a vineyard in the foothills.


Below Ground Factors Influencing Vine Balance

Pruning and Training Principles for Balanced Vines

Larry Bettiga is the UCCE Viticulture Farm Advisor in Monterey County.  He has conducted numerous studies on the effects of cultural practices, rootstock and clonal selection on grapevine growth and productivity, including recent work on the effect of planting uber vines.
