The Q&A Archives: Overwintering Daylilies

Question: Can I leave the Stella de Oro in the same pot over the winter and will it come back next year does it have to come inside?

Answer: Daylilies will winter over outdoors if they're given a protective mulch, but leaving them outdoors in a pot could freeze the roots solid. You can leave them in the pot and bury the pot in the ground, covering it over with several inches of mulch material this winter. Or you can dig and store the roots after the tops die down. I've kept my Stella de Oro's in a pot for 3-4 years before they needed to be dug and divided. I'll bet you can do the same with yours!
