Tee, don't mind my asking but if there is a freeze, which means that water crystallises, what about the water in the tissues of the plant, wont it become shard and burst the cells?
See, if you put potatoes in the deep freezer then take them out after some time are they edible? Edible in this instance means are they worth eating and if not why? Try it and you will understand what i am trying to say.
