Sudden Oak Life by Lee Klinger

in 2015 I began applying fire mimicry treatments to a grove of sick coast live oaks. Yesterday I checked on their status. Here are the photographic comparisons showing that the density and greenness of the oak canopies has increased noticeably after four years of treatments. However, two severely diseased oaks did not respond to the treatments during this period and had to be removed. Fortunately, the remaining oaks appear healthier and the prognosis for recovery is good.
