Grape Hardiness Update for Mid-January - Kelowna and Similkameen Supplement
Attached are the Supplement 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 10th and 11th in the Okanagan and Similkameen Valley.
Additionally, in response to the current extreme weather event where low temperatures are expected to persist over an extended period, viticulture research technician Brad Estergaard has also included some results of work looking at exposure time as another important variable of grape vine hardiness. The data is from Merlot vines located at the Summerland Research and Development Centre in Summerland, BC.
