Here’s a fascinating bit of information picked up at this morning’s Master Gardener class at the Minnesota Landscape Arboretum. How much difference does snow make in insulating plants? According to researchers at Rutger’s University, 9 inches of snow cover can make a 42 degree difference in temperature. According to their experiment, if the air temperature is -14 degrees F, the ground temperature under 9 inches of snow would be 28 degrees.
It must be about 85 under those monster piles at the end of my driveway!
