Cold Damage
This is a problem in Texas mainly due to sudden changes in temperature in late fall through early spring. Mid winter cold damage kills the cambium layer causing it to turn brown. South west injury is the killing of the bark on the southwest side of the tree. This occurs because the bright winter sun heats up the surface cambium of the tree during the day. Thus this area is not as dormant as the rest of the tree. When the sun goes down, it is the southeast side of the tree which was last warmed by the sun. Thus it is this side of the tree that goes through the most extreme change in temperature which can lead to tissue death. Damage at bloom is to the young developing flowers and fruit. As the flowers begin to open they lose hardiness. At full bloom, the flowers can be severely damaged at temperatures of 28° F or lower. Small fruit can be severely damaged at 30° F or lower.
