Sorry but what zone are you in? I started ginger a year ago in the late spring and it came up and grew really well. I wish I would have had taken pictures. Before frost I cut down the dead greens and scattered them on top, then placed more
straw on it. I then topped it off with big rocks, to try and insulate the roots. I will know if this was successful this spring, but as far as one growing season goes, it went really well, and it was yummy.
Im in zone 6.
