Likely, overwatering. Unfortunately, your photo did not come through, so I am unable to see any damage. Extreme cold can do this as well, over the winter.
I would make sure to use fungicide on the plant and area around. Make sure that it only receives water when the ground has dried, very thoroughly, down to about 4 inches or so. Most of the time, they are drought tolerant and will not need supplemental water.
