2-years Pre-plant · Replanting Existing Vineyard Sites

Are there any special considerations for tearing out an old vineyard and planting a new one?

Studies have shown that replanting grapevines in soil previously planted to grapes tend not to thrive, or they rapidly decline over time. Although many factors have been determined to cause this lack of vigor, it is important to remember that to reduce the likelihood of these problems, growers may need to pull out the existing vines and allow the land to lie fallow - with a cover crop, say, rye or alfalfa - for one, preferably two, years prior to planting. Otherwise, note that posts and wires can be reused in replanted vineyards, and additional preparation can be completed as described in the Site Preparation page.

Steps to Mitigate Replant Issues

  • Soil testing. This is a common theme in grape production; for most questions regarding vine health and vigor, extension agents always ask first, "Have you done any soil testing?" Obtaining a complete soil test will enable you to know what amendments the soil needs. Applying soil amendments before a trellis is installed is far easier than trying to find equipment that will fit between rows AND spread the material effectively.
  • A local extension educator can provide growers with information on soil testing and recommendations based on test results.
  • Herbicide history. Some herbicides - such as 2,4 D, glyphosate, etc. - can have residual activities and negatively affect vines in the year subsequent to their applications.
  • Plant a cover crop for 1 to 2 years prior to planting of vineyard. A cover crop can increase soil organic matter and improve nutrient availability to vines.
  • Compost. Some studies in plant disease control have demonstrated that composts can have disease-suppression effects in disease-infested soils. Growers may want to consider compost application during replanting of vineyard sites.

Katie Gold Named New Grape Pathologist

Katie Gold has been named as the new assistant professor of Grape Disease Ecology and Epidemiology at Cornell AgriTech in Geneva. Katie is currently completing her Ph.D. at the University of Wisconsin - Madison. Upon completion of her Ph.D., she will conduct postdoctoral research at the NASA Jet Propulsion Lab (JPL) in California from August 2019 through January 2020. While at JPL, Katie will gain experience with the latest hardware and software for remote imaging with future application to digital agriculture and grape production. She will begin her tenure-track assistant professor position on February 1, 2020 with responsibilities that are 60% research and 40% extension.

Her research and extension seminars were on the topics of "Hyperspectral systems for pre-symptomatic potato disease detection" and "Agricultural sensors in Grape IPM", highlighting some of the tools and approaches that she will bring to the position. Katie is already setting up collaborations for her grape work in New York and plans to attend the American Society for Enology and Viticulture - Eastern Section Meeting in Geneva this July.
