I'm in Forney, just east of Dallas. I have several daylillies in pots of various sizes and depth of dirt. I've kept them watered-well during the summer, but with winter coming, I'm not sure how to protect them. There are too many to put in the garage. If I cover the pots with leaves and surround the pots with dirt and leaves, do you think that will be enough to protect them? They are in the sun in the backyard grouped in rows. They are sitting on the ground that is covered with a grass barrier. Should I put something under them, too?
