Dr. Justine Vanden Heuvel, Associate Professor of Viticulture at Cornell University, describes how controlling vine vigor is difficult in regions with high organic matter soils and plentiful summer rain. Growing certain cover crops in the vine row can devigorate vines by as much as 30%. Others do not devigorate vines, but do keep soil in place. In vineyards on slopes under-vine cover crops can reduce or eliminate the need for herbicide applications preventing the off-site movement of soil, pesticides, and nutrients.
