The locally respected Farmers Almanac says that the average first frost date for our neck of the woods - Grand Forks, North Dakota is September 27. That isn't stopping Mother Nature from trying to send us freezing weather two weeks earlier than the average first frost date. The weather forecast is for freezing weather tonight/Wednesday morning and possibly Wednesday night/Thursday morning.
We'll tuck in the tomatoes and peppers in a nice warm blanket overnight to make sure they stay warm and cozy. It seems like it's too early in the season to be worrying about frost, heck it's not even officially autumn yet, but you can't argue with Mother Nature, she's gonna do what she's gonna do.
