Grape Hardiness Update for Mid-January 2024 - BC
Attached are the Winter Grape Bud Hardiness results for mid-January. The sampled hardiness levels were determined as average lethal temperature exotherms (LTE) measured on buds of several varieties by region collected on January 16th and 17th in the Okanagan Valley.
**Of a total of 540 buds sampled only 3 exotherm peaks were observed. The values are given for the 2 locations where these were observed but the exotherms are likely from remnant tissues of already damaged buds.
