Some mulch and snow insulation goes a long way.Yes, most of what I have outside can take the cold (larches and spruce) but I am beginning to worry about my big hinoki. It got down to about 9 last night but will stay about 20 overnight through Friday. Root kill temp is 15F and I have it on the ground and mulched in so I am pretty confident it made it through last night but Saturday night could be bad when it is supposed to hit 5F. Guess I need a bigger greenhouse!
This is from a temp probe in the substrate of one of my Japanese maples for the past day.
We've had a good amount of nights in the negatives, and I haven't seen it dip below 28 or 29.
