At least the more snow helps to cover my Pine trees. I have not completely covered them because they are also positioned close to my house, even though I could easy do so with the amount of snow that we have had.
The deciduous trees are still in my garage on the heater bed. I have had this on a couple of times to relieve the temperature a little, but the good thing is that the garage is keeping the temperature some 8-10°C warmer than the outside temperature. As you can see I have placed some snow on the pots which will slowly melt into the soil to prevent the soil from drying out.
