I pot up my excess fans as singles every July in gallon pots in potting soil. I leave them to grow for a month to make sure all is good. Then I sell some to anyone interested. Leftovers stay in the pots but I sink them down into some raised beds I have. In March or when they earth has thawed enough that I can get them out of the ground, I move the plants into the greenhouse to grow. They wake up quickly and by plant sale time in May, they are looking good. Some even have buds depending on the size of the rhizome.
