I would have started them indoors if I had known the weather would turn cold. As it was, I planted them the day after they arrived in the mail from Freshhops.
I just have no idea how long they can tolerate being in the ground and not growing. I know if you plant potatoes too soon they will rot in the ground before they can grow.
We've also had two or three soaking (almost flood-like) rains in the last couple of weeks, but the area where they are planted drains pretty well (no standing water), so I'm crossing my fingers.
