Finally went out and pulled the plants that had died in the cold snap we had a couple of weeks ago. This includes the pineapple, peppers, and green bean seedlings. It also appears that the carrot seeds I planted a while ago did not wash over into another square as I had thought, but were actually planted there by mistake. Ooops. So now I have carrots and lettuce growing in the same squares, and two more squares empty. :) We’ll see what happens.
