somebody is going to tell me to go down to 4 feet 6 inches, but 4 feet 2 inches is all i’ve got. it’s basically impossible to get last 4 inches with the post hole digger i have. i had to cut through some small roots but got very lucky i was able to dig down and just miss a very large root that i wouldn’t have wanted to damage.
hi. ho. if the frost goes down that far, it wins.
i found a piece of a glass bottle 3 feet down which seemed like a long ways down to be finding glass.
