Hi All,
As with many of you, I obsess about winter protection this time of year. I have come to believe that many of us (myself included) go way overboard on protecting our trees. I often see people advocating to have trees placed on the ground and mulched to allow the earth to better insulate. While this intuitively makes sense to me if you have a very small and/or shallow pot, I'm not sure if it makes a difference if you have your trees in a wooden grow box, mica pot, Anderson flat, etc where there is already a sufficiently large volume of soil in place.
Is anyone aware of any references or has anyone made any temperature measurements with different overwinter protections? Let's ignore the effects of wind and desiccation as there are other ways to compensate for these (wind barrier/fence, regular watering). I am also specifically just talking about the temperature of the roots/soil media as these are the most sensitive components of bonsai to winter damage.
I am up for some controlled experiments, if no one has any direct measurements.
Sincerely,
Lars
