Now I truly believe it isn't the cold that kills these things, it's the way they retain moisture, freeze, melt, refreeze, etc. Also pretty sure no matter what you protect above ground hardly matters as much as the root system deep below... Just my $.02.
Either way, it was a pretty long, cold winter here on the east coast in the US. Hope a bunch of others had better luck!
Evidently it was a great winter for surfing in NJ tho
