I wonder if it was so much the bubble wrap as her method of wrapping?
Citrus trees die from the cold not because the leaves freeze but because
the thin bark on the trunk freezes. If she tried to protect the leaves
but let the trunk exposed the tree would wilt the very next day.
Bubble wrap should be a good insulator because of the many dead air
spaces. The plastic itself is a good insulator and if she used two
layers it should have worked for a normal freeze. Subzero temps would
call off all bets.
