In November of 2000 I began fire mimicry treatments on several ancient coast live oaks and madrones in Felton, CA. Many of these oaks are likely over 400 years old and date from the time when the Ohlone were the sole occupants of the land. Earlier this week I checked on their progress. I’m please to report that, after three years, all the oaks are showing noticeable improvement, and all but one of the madrones also appear to be thriving. Here are the full set of results.
Three years ago I began fire mimicry treatments on five oak trees here in Big Sur. I also performed a large canker surgery on one of the trees, an Ancestor oak that is about 350 years old. Here are the results captured with repeat photography. Enjoy!
While most of my results are with coast live oaks, I also work with other kinds of oaks. Here are a set of results among black oaks I’ve obtained this past year using fire mimicry methods. Several of these black oaks were severely diseased with Sudden Oak Death infections. The oaks were given compost tea, soil mineral, and limewash treatments, as well as the surgical removal and cauterization of a Sudden Oak Death infection. The surgeries appear to have worked well, as the canopies have improved in lushness and density and there are no lingering infections in the remaining trunk tissues.
In November 2020 I began fire mimicry treatments on several coast live oaks and Pacific madrones in Felton, CA. Last year, when I checked on these trees, they were already showing a nice improvement (see here). Now after two years nearly all of the trees are showing noticeable positive responses to the treatments, even at the height of drought conditions. Several of the oaks have undergone major stem canker surgeries, but still seem to be on the mend. Hope you enjoy these results as much as these trees.
In October of 2020 I began fire mimicry treatments on 4 coast live oaks and one black oak here in Big Sur. The above oak also received a major stem canker surgery. Yesterday I checked on the progress of the oaks at the two year mark, nearly to the minute. I’ll never tire of seeing trees get healthier!
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!
Yesterday I did fire mimicry treatments and a minor stem canker surgery on an ancient coast live oak in Atherton, CA. The surgery went well and the prognosis for this oak is very good. Here are photos showing the various steps and tools used for the surgical procedure …
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 …
Several years ago I started fire mimicry treatments on a coast live oak in Big Sur, CA. The treatment included stem canker surgery, as well as soil fertilization and limewash application. Here is a set of photos showing both the surgical procedure and progress of recovery of the wound and the canopy health of the oak. Be sure to look at the final photo of this sequence!
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.
