Did you get any replies? What is your climate zone? This is my first time to find this website. The other cardoon prep thing I found said to boil in 5 changes of brine to get rid og the bitterness. They taste like …salt.
Has anyone reported Deep mulch or bringing roots/crowns inside to winter over? I am zone 3b i think. The map says 5a but it gets to -30 every winter.
My grandmother told me her mother always harvested her celery then brought the plants in and brought them out of the cellar one at a time to force for fresh celery all winter. This would have been South Dakota over 100 years ago. I doubt she ever heard of cardoon but would have been entranced.
