Six years ago I began fire mimicry treatments on several coast live oaks in Carmel, CA. Three were infected with Armillaria disease, so I also surgically removed and cauterized the Armillaria stem cankers. Here are the results from a few says ago. Most of the oaks are showing denser, lusher canopies, and 2 out of the 3 Armillaria surgeries I performed appear to be successful.
The photos below show a successful Armillaria canker surgery on a large coast live oak.
