I'm sure the overwintering process for EE's has been covered. I am familiar with digging up the inground tubers and storing them. However. I'm trying to overwinter two "potted" EE's I understand you can cut back the leaves/stems to about 6 inches and bring in the pots. I am hoping to keep them dormant till spring. Is there anything else I should do? Does the soils need to be dry before bringing in the pot? Any suggestions? Thank you!
