A Simple Method to Evaluate Whole Plant Cold Hardiness

Whole plant assessment is direct, requires a minimum of equipment and expertise, and provides a good approximation of actual cold hardiness. Potted test plants are subjected to several target temperatures in a slightly modified domestic chest freezer. After gradual warmup, the plants are placed in a favorable growing environment for 7 to 14 days, and then the percent of cambial damage is determined. The temperature at which 50% damage occurs is determined graphically.
