To my fellow cold climate growers. I'm staring down -50 windchill in two days. Ambient temperature is supposed to get to a low of -26. I have pretty good wind breaks in trees and structure around the vineyard, but I don't think I'll be lucky enough to avoid the worst of the cold. I've seen some northern growers ice their vines when looking at conditions like these in order to protect them from the wind damage, and I'm a bit curious about the effectiveness and process. How thick does the ice need to be to be effective? Do you only ice the canes and leave the trunks alone? Is it effective? Any tips would be great.
