The polar vortex did not stay very long, thank goodness. It got down to ten below zero here, but within a week it was in the 50's. Sixty degree rise in one week! The day before the cold arrived found blizzard conditions nearby in Indiana and Michigan. Honestly, I was hoping the snow would come here too, to protect my garden from the upcoming frigid temps. But no such luck. And I doubted that the snow dust on the ground would provide one bit of protection. I went out today to check on things. Imagine my surprise to find Miss Ladybug moving around. She's a tough one!
