This is my report on overwintering my proliferations. All the ones I put in the ground in pots did not survive the winter. I guess their roots are not developed enough. I sunk the pots down in the soil as if they were planted there. The ones I grew on the window sill in the kitchen all winter are now growing into healthy plants as I transplanted them outside after the last frost. So next year, any prlifs I grow will winter inside. If I had a garage like yours Jan, I would use that. However, my garage is detached and freezes as does our greenhouse.
