Attached are the Winter Grape Bud Hardiness results for Late January / Early February.  The sampled hardiness levels were determined as average lethal temperature exotherms (LTE) measured on buds of several varieties by region collected on January 31st and February 1st 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.
