I trimmed a root sucker from a japanese quince and have been rooting it in sphagnum moss, inside of a gallon tupperware under a grow light. I'm pretty confident that it'll take, but there's no way the roots will be ready for a hard Chicago winter. So I'm gonna overwinter it indoors under a grow light and cross my fingers, basically. The sucker would have to go anyways so it's not much lost if it fails but I'm wondering if I should bother with keeping it in the fridge or something.
