Pat, I hope the cold will kill all the rust spores for you. It sounds like if the foliage is frozen, the rust will die with it.
Let's just say I receive the new daylilies and plant them in the pots. After a week or two, I notice that they have rust. Besides isolating them, what else can I do to eliminate the rust from the plants? Do I strip off the foliage and spray it with fungicide? Will this kill the spores?
