Awe, that is too bad, try again, only get younger ones. When I cook asparagus I bend the stalk and where it breaks is what is the tenderest part. The other part, which is more tough can be used, but I like to only cook the most tender part. Asparagus would only do well in a very large pot. Those root crowns are enormous. When we moved up from the coast to the Okanagan, I lost about 100 five gallon pots of perennials I had so carefully dug up, potted and moved. Only a few of them made it through the first winter. Too cold, probably the sudden change and being in pots over winter. Asparagus was included in this. I lost about 20 crowns, sigh....lessons learned. It is OK though, I really don't have room for all the perennials anyways, but yes, plants in pots don't weather well with extreme cold I think. I would not try with asparagus. We get very cold here in winter and we have lots of asparagus farms around. You could grow it inground I am sure where you live. Have a beautiful day, CynthiaM.
