Five years of surgical wound recovery in a coast live oak

13 04 2022

As I’ve shown in several recent posts (here and here), results are starting to accumulate regarding the efficacy of surgeries to remove stem canker infections (including Sudden Oak Death disease) in oaks. Five years ago I performed fire mimicry treatments and a stem canker surgery on a coast live oak in Los Altos, CA. I have returned every year since to track the progress of the wound recovery, and whether any infection remained. The set of photos presented here indicate that after only 5 years the surgical wound has healed closed with no sign of further infection. I’m calling this one a win!

Fire mimicry treatment and surgery on a coast live oak in Kentfield, CA

5 04 2022

In 2018 I began fire mimicry treatments on a grove of coast live oaks in Kentfield, CA. One of the oaks started showing signs of a stem canker infection (probably Sudden Oak Death disease) in 2019. So I performed a surgical procedure to remove the canker, and have continued to treat this oak with compost tea, mineral-rich soil fertilizers, and limewash. Here are photos of the surgery and recovery of the wound and canopy. Be sure to look at the last picture of this series …

More photos showing a surgery on a stem canker infection in a coast live oak

4 04 2022

Here are a set of photos showing a surgical procedure on a coast live oak in Santa Cruz, CA infected with a stem canker disease (probably Sudden Oak Death). This is a good example of a major infection that appears minor at the surface. The surgery ended up being fairly large for a tree this size, but I do believe the oak will recover.

Big Sur oak continues to flourish 4 years after canker surgery

10 03 2022

Four years ago I performed fire mimicry treatments and two canker surgeries on the above coast live oak in Big Sur. This oak was treated again two years ago. I checked on the oak yesterday and found it has completely transformed into a lush, vibrant tree. The bit of yellowing seen at the tips of the branches are thick clusters of male flowers. The two surgical wounds (below) have mostly healed shut will no remaining infection in one and a minor residual infection in the other.

Another nearby coast live oak was also treated twice with fire mimicry in the past 4 years, although did not require any surgery. Here are the results of that oak.
