Scorch is Plant Stress

I have 5 choke berry bushes by the house and they all show plant stress. They have done this in previous years. It isn't best for any plant but usually not life threatening. Leaf scorch, as this is called, is when the plant is loosing (transpiring) more water than it is taking in. For more information on scorch, go to http://www.hfrr.ksu.edu/p.aspx?tabid=586#S
