BC Growing Degree Days - July Update
Growing Degree Days results for April-July for Summerland and Osoyoos.
Cold weather remains an ongoing challenge for the grape and wine industry across Canada. While climate change is predicted to expand areas suitable for wine grape production in the country, more frequent extreme cold weather events through the year, including cold episodes lethal to grapevines are also predicted. Activities 5, 6 & 7 will explore methods to reduce crop loss risks by increasing vineyard tolerance to extreme cold events through enhanced hardiness, crop protection technologies and improved cultivar selection.
