[quote=Pancrazio;284285]I see what you mean. Acute and extended damage are definitively two different things. I think that the key point is to have at least some daily temperature above 32F. I think that ice started forming inside the plant but wasn't capable to do too much damage because during the day it unfreeze.
Also, i'm interested to see the other thing you point out: how well the plant behaves when there are several cold spell over 2-3 months.
This year we got just this cold spell, and it is pretty unusual for me (we get usually several during winter); but i'm happy because this way if in the next years i get some damage from several cold spell in row, i can tell for sure that it isn't the single cold spell doing most damage, but the sequence of cold events.
Hey asacomm, I'll do it for sure, I always have read your post on the way you used to overwinter your plants with great interest, it's time to reciprocate.
I Plan on posting my results in about two weeks, when any threat of cold temperatures are done and I gave enough growth to report success...I experimented with many things - some things left totally unprotected, wrapped trunks on others, some lifted and pitted and cold stored in a garage, and some cold stored barefoot. I will definitely know what I want to do next year! We don't have cold winters here compared to most of North America, but we have enough winter to matter. Looking forward to a move to Florida in a year or two.
