I am throwing this out here to my friends:
My coworker lives in a condo but is able to garden alongside her end unit. She had beautiful and well cared for perennials, with a lot of daylilies.
She and her husband are having a screened porch built, and she has had to dig up all her daylilies. They are currently waiting around to be replanted.
But, a month ago, she purchased more daylilies at the Local daylily sale, and they have been sitting in her garage, just in the plasitc bag she carried them home in. She has allowed daylilies and iris to sit like that for periods of time, bare rooted, without problems, and now wonders if she can leave these daylilies in an insulated garage (doesn't freeze, but not hot) all winter & just plant them in the spring. She did purchase these before they made the decision to tear the old porch off & rebuild a bigger one.
Any thoughts? I told her no "pot planting" of them up here, because I lost all of mine last winter doing that, although if she chooses to do that, I will warn her to tip those pots on their side when things start to warm up. I tried overwintering some of mine last year in my unheated but insulated garage and had all sorts of problems, from rust to aphids, to everything in between before I tossed them outside & lost them this spring, with the warm up then freezing temps, so at least in south central Wisconsin, I do not recommend that.
But leaving them barerooted? I have no clue if they would survive.
Any thoughts, ideas? Thanks everyone! ~Jan
