Sometimes frost damage is apparent almost immediately following freezing. This works where the weather provides a prolonged slow chilling In very severe climates such as within the arctic circle native trees remove water from their cells, tolerating the dehydration of the cell contents, and place the water between the cells where it can freeze without causing damage.To do this plants have to experience several days of cold weather before the freeze and this explains why even hardy plants can be damaged by a sudden autumn frost A more effective mechanism is the ability of some plants to allow their cell contents to 'superfreeze' where the cell contents remain liquid even though below freezing point.Some plants accumulate materials, certain sugars and amino acids for example, that act as anti-freeze lowering the freezing point of cell contents – shortening autumn days induce this. ![]() Sometimes bark can insulate the living water-conductive tissues in the same way that water pipes are lagged to prevent water freezing within cells.Plants can survive frosts by several mechanisms: How do plants protect themselves from frost damage?
