Does snow help to insulate plants against cold?
When I was growing up in Wisconsin, my mom was always glad when there was a snow cover when the bitter cold arrived. She always talked about how it protected her roses from the cold. Is this true? Does snow act as an insulator? I sure hope so! My sweet peas, allysum and snaps are all covered with snow right now, and the temp around DFW is supposed to be about 10 degrees.
