Grape Cold Hardiness Exposure Time

January, 2024

In response to the current extreme weather event where low temperatures are expected to persist over an extended period I have attached some results of work looking at exposure time as another important variable of grape vine hardiness.  The data is from Merlot vines located at SuRDC in Summerland, BC.
