Fire mimicry results with Lebanese cedar, sycamore, redwood, and coast live oaks

Several years ago I began fire mimicry treatments on some Lebanese cedar, sycamore, coast redwood, and coast live oak trees in Los Altos, CA. The before-and-after photos  shown here indicate that the treatments were effective in improving the health of the trees.

The coast live oak above was diseased and nearly dead when I first treated it. I told the owner that I did not think the tree would recover. But 4 years later, the oak is showing slight signs of recovery.
