For those of you who over-winter your hardy pond plants outdoors, how do you do it? I'm considering burying some small pond tubs in the ground for overwintering hardy pond plants but I'm not sure how deep they need to be to protect the plants well in this area. I've read that our frost line is at about 2 ft, so do any ponds need to extend below that to protect the plants from the abuse of freeze/thaw?
Last year I left most of my hardy pond plants outdoors and kept them moist but not submerged. Some made it but many did not. I brought the more sensitive ones into the garage near the window where it will get down to freezing on the coldest days but not much below. Most survived quite well. I've got a lot more pond plants this year and it'll be quite a bit of work to bring them all into the garage which is why I'd like to leave some out if I can.
