Understanding Cold Hardiness

Plant Talk with Mike YannyAbstract

Where many plants run into trouble is when temperature swings are so rapid they don’t have time to adjust. This causes their cells to explode. It is similar to an undrained water pipe freezing and blowing apart in winter. When the water freezes, the pipe expands and breaks. If plant cells are not prepared properly, they will do the same thing. It is quite common to see cold temperature damage on plants caused by cells exploding. It usually happens in late fall or late winter when plants are not fully acclimatized or are de-acclimatized due to late winter warm-ups.
