Hi Kim. We can probably help depending on the type. I understand some folks call a rather large white tuber HR. We have the type that grows in the ground as a root, extremely hot, dies back in winter and comes away spring. Used for sauces etc. Is this what you want? Paul.

My late husband always dug and replanted horseradish in July, Is this too long in the ground, he usually replanted the crowns. I am not having a great success
