I planted out four of my 12 tomato plants last night. One each of Super Marmande, Rutgers, Gardener’s Delight and Cold Set.
According to the chart I found for Illinois historic temperatures, after April 24th there is only a 10% chance of having another 32 degree night.
Tonight’s low is supposed to be 41, and the forecast shows the daily low rising for the next 6 nights. Hopefully there won’t be any frost tonight, but even if there is, I have more plants ready.
