Attached is the Winter Grape Bud Hardiness results for Early April.  The hardiness levels were determined as average lethal temperature exotherms (LTE) measured on buds of several varieties by region collected on April 9th and 10th in the Okanagan Valley.

This is the final grape hardiness update for the 2018-2019 winter season.  It’s time to switch gears toward the growing season so the monthly Growing Degree Day reports will start again in May.
