Last month I got 4 trays of wheat grass. I cut it almost down to the roots and split it between the piggies. I thought that rather than leave it in the plastic trays, I'd experiment with it and I planted it in the garden. I didn't expect much, but I was pleasantly surprised that it has really taken off. It's not getting overly tall, but it is twice as thick as it was when I got it. I'm anxious to see how long it lasts.
