Re: FreezePruf - It's here!
Exactly, different plants are going to respond differently. I also think that in places like where I live where some plants never go fully dormant it is tougher on them when it gets cold. Also, we can have dramatic temerature shifts here...70 degrees one day, down to freezing the next. That type of change is very tough on plants as they have no way of coping in such a short amount of time. Up north, plants slowly shut down for the winter. Rarely are they actively growing and then, BAM, freezing temps the next day like can happen here in the south.
Duration of the freeze is also important. Often, here in Houston, we'll only receive frost for a couple of hours. This last round of cold weather we had here my plants were exposed to about 10 hours or so of freezing temps which really does a lot more damage than just a couple of hours of freezing temps. All of these things affect the way plants tolerate the cold and whether or not they receive damage.
