Field-grafting grapes not a sure thing

摘要

Conditions must be just right when field-grafting grapes in cool climates. Field grafting wine grapes has successfully been done in Washington State. However, grape growers attending a Washington State University viticulture and renology field day learned it's not a sure thing, and high percentage takes are very dependent on timing and weather. Grandview, Washington, grape grower Dick Boushey of Boushey Vineyards shared his successful and not-so successful field grafting experiences during the mid-August field day sponsored by the Washington State Grape Society. He showed growers and winemakers a two-acre block of Semillon grapes planted in 2003 that were grafted earlier this spring to Sauvignon Blanc.
