All of the hosta and fern were moved to the 'pen'. The only thing on the rack is the erythronium in pots. Since they're a perennial bulb, they should be ok. I may bury them under leave too, but haven't decided yet.
I actually don't have the racks directly on the ground because of leveling issues from tree roots. I set them on some of those 12x12 concrete pavers. The racks themselves are made up of plastics and metal tubing. Each level has a plastic retainer on each end and three metal tubes between. An open wird mesh shelf is then placed on top. The levels are separated/joined by a metal tube in each corner. This will be the 2nd winter for one set and the 1st for another. (The others are indoors.) I keep meaning to take one of the plastic retainers to HD to see if I can get PVC tubing as replacement pieces when necessary. Or, some reasonably-priced facsimile. (Copper would be nice... and expensive!)
