I will have to research the average highs & lows for that time period as am not sure. It could be anywhere from the 60s to 30s for the daytime highs to lower 30s to mid 20s for nighttime lows. But don't hold me to it until I get a chance to look that up. And the soil here is very crappy, so just about anything I add would be an improvement. I was Mn born and raised and had never been out of the state before moving here. When I first saw the dirt and saw it was brown I said what's wrong with the dirt? I had never seen anything but black dirt before that.
