It was 5 degrees officially this morning, no breeze, very still. On my own thermometer here at the house it was 0.
We've always been in a little cold sink, a dip between the two ridges that surround us, and a frost will hit the plants at the edge of the meadow when it doesn't affect any others. When it is still, it can be four or five degrees colder in the meadow.
The porch is down to 34 degrees. It has never gotten to freezing on the porch, but this is awfully close. The plumbagos that are overwintering in pots are probably not going to like this.
Thank goodness for the blanket of snow protecting everything, especially the rosemary.
