I'm looking forward to the pictures of your new raised bed next spring! Do you leave the pots with the broken roots out all winter there? I have a couple of large plastic pots already with broken bits in them, think their 3 gallons, that I was going to leave out to see if anything sprouts. Haven't decided if I'm going to try to sink them in a raised bed or just leave them in a protected spot. Most of the winter I think they'd be fine but we typically have at least 7-10 nights of -10 degrees or so during the winter, think those might be a challenge for anything in the plastic pots.
