How soon does the ground freeze?
We've had an unusually warm fall, and I was hoping to dig some garden beds this weekend with a new powered plow. But the minute I placed the order last week, temps plunged into the twenties and, this week, are forecast to be in the teens. (Yes, sorry, I'm the one who caused the cold snap.)
How may days of freezing temps does it take to freeze the soil solid? I'm wondering how much chance I have of actually getting some beds dug before, say, April. Or May, since the ground will probably still be wet in April.
