freezer for several hours, and then fill it with warm water, and
you will have your answer. Don't do this experiment with your
favorite glass because it won't be usable afterwards. It will
shatter exactly as frozen plant cells do when warm faucet water
strikes them. The best way to prevent cell damage after a light
freeze has occurred is to attempt to slow thaw these cells. This
can be accomplished by covering plants with a sheet or blanket
to shield them from the warming sun rays which will do the same
harm as warm faucet water. This technique will also work on
certain ornamentals such as petunias. Remember, survival is
possible only after a light frost or freeze; after a hard cold
