Attached is the Winter Grape Bud Hardiness results for late March. The hardiness levels were determined as average lethal temperature exotherms (LTE) measured on buds of several varieties by region collected on March 25th and 26th in the Okanagan Valley.
This is the final Bud Hardiness Report of the 2019-2020 winter season. Bud hardiness data was not collected on April 8th and 9th as the Summerland Research and Development Centre was closed due to COVID-19.
