In late autumn (October November) all horseradish roots are dug up and pounded in the cellar for later consumption.
You have to be careful, that even the smallest root pieces are included. Otherwise, these will develop into a very annoying weed in the years to come, because even the tiniest piece will sprout again. In the basement, the poles are hammered into damp sand. But the basement must be cool, otherwise the horseradish will sprout in the course of the winter and the practical value of the sticks will be reduced. If kept cool, horseradish will keep for many months.
