I have 2-year-old Apache blackberry plants that are producing great for the first time. My problem is out of 5 plants, two of them have leaves that are turning brown falling off. I am worried the plants are drying. They start out getting a real pale color and then turn brown and fall off. Do you have any suggestions on what this is and what I can do to prevent the plant from dying? It is still producing blackberries.

Have you noticed any orange coloring on the leaves as well? Blackberry leaves that are heavily infected with blackberry leaf rust (which commonly affects these plants) turn brown, shrivel, and fall from the canes.
