Tomatoes? In the ground? Before the last frost date? Madness, surely! Nonetheless, did plant 10 tomato seedlings that have been growing in the basement. My calculation in the matter was that if they all died, we still have 5x more seedlings than we need. Planted 4 of them in wall-of-water plastic bags. This is supposed to protect them down to 16 F, and the worst low in the forecast is only upper 30s. If they don't freeze, we've definitely got a good jump on the season.
