I usually say that people who ever so gently dig to find a shoot have way too much time on their hands, and are the truly obsessed. Maybe for Kushi Maya I'll make an exception.
It's hard to know what was the temp of the soil where the bulb was when it was 20 below. (Now you try making a sentence without a comma and three was's.) If I remember right, here in Minnesota we were actually about 5 degrees warmer at that time, but still with no snow. However, when we did get a thick blanket of the white stuff, the frost came out of the ground in many areas here. So the cold must not have penetrated that deeply here. What's that mean? I dunno.
