It's 85 here right now, bright and sunny. I just came in from working in the garden. Can you believe it's possible to work up a sweat in March? To be honest, I'm not used to that.
At 8" down in the soil and according to Washington State U, the ag sites never had any of their locations at below 30°f this winter ..!
Lots of snow made lots of insulation. At 4', we figure it's 55° year around and 32° water from the melting snow took the frost right out of the ground. Doesn't always work that way, here. Too often, we have lots of sub-freezing weather with little or no snow cover.
