Grape Hardiness Update for Mid-February 2023 - BC
Attached are the Winter Grape Bud Hardiness results for mid-February. The sampled hardiness levels were determined as average lethal temperature exotherms (LTE) measured on buds of several varieties by region collected on February 14th and 15th in the Okanagan Valley.
*Missing/blank data is the result of the absence of any observed exotherm events from the collected samples. Also note that some of the observed exotherm events may be from remnant tissues in already damaged buds.
