Two years ago I began fire mimicry treatments on a grove of sick coast live oaks in Big Sur, CA. Most of the oaks have responded well, including several that underwent surgical removal of bleeding stem cankers (probably Sudden Oak Death). Here are the before-and-after photos of the treated oaks. Note the photos are the same date, time of day, and light conditions as original photos.
