Ya'll must be planting a different kind of pea than what we plant down here. We don't start planting peas until now and its in the 70's everyday, sometimes 80's. In fact it seems like on my extension's web site it doesn't recommend planting peas until the 10th. I don't plan on planting mine until next week, which is when I plant okra. Both need really warm soil to start off right. These and eggplant have always been two of the last things that we plant in our first planting.
I'm just guessing, but maybe ya'll are planting the ones that come in cans at the grocery store here, little green ones? We plant what we call field peas here, I don't know of anyone that grows the little green ones around here.
