Are you expecting frost tonight?
No, not yet.
Even if Springfield or Jeff City were to frost, most of the lake valley would remain at 35 because of the lake water temp. Lots of steam visible each morning. This won’t last much longer.
We had almost incredibly good luck with our paste tomatoes planted to a pair of 4 X 10 beds. There are limited sunny spots on our acres but we get a running start by starting seeds in February and more or less ‘green housing” them until they’re ready. We follow up with hoops and white garden covers that allow earlier transplanting.
Lake water watering on a timer is also useful. Seeds came from Baker Seeds in Missouri.
