Gerry glad to know your idea worked! When I tried keeping potted daylilys in my insulated garage several years ago, they not only developed Rust but also got mites. I have overwintered other things in that garage previously and never had a problem. So I put all those pots outside, and protected them well. They survived the winter, and rotted in the spring. At the time I didn't know about turning the pots sideways and lost every single one. I know others that use coldframes without much problem I just know that for me, that experiment failed
I have been away from home for a week, and know it is still cold at home, it will be interesting to see what changes have occurred while I have been away
