Fire Mimicry: Treated vs. Untreated

As most of my clients chose to have me treat all of their oaks with fire mimicry, I don’t often get the chance to compare treated vs. untreated oaks in the same landscape setting. However, last year a client had me treat come oaks, but not the others. Here are the before-and-after photos of two oaks that were treated (above), compared to another that was not treated (below). One of the above oaks (Case No. 20181203.2) was infected with a stem canker disease (probably Sudden Oak Death), which was surgically removed in 2018.

Culturally-modified Indian-era oaks respond to fire mimicry

15 11 2019

Slide1

Five years ago I began fire mimicry treatments on a grove of ancient, Indian-era coast live oaks that have clear signs of being culturally modified (ie. pollarded). This past week I checked on the status of these oaks and the entire grove continues to show strong improvement in canopy density and greenness. And in an area of rapidly spreading Sudden Oak Death, none of these trees have contracted this disease.

Oaks and other trees in Atherton, CA respond to fire mimicry

7 06 2019

Slide1

Last year I (and my dedicated crew) treated several coast live oaks along with a valley oak, a California buckeye, a jacaranda, and an ornamental pear with fire mimicry. Yesterday I inspected and re-photographed these trees. Here are the photos showing the results after just one year. I’m happy to report that most of the trees are showing a noticeable increase in canopy density and greenness. BTW, four of the coast live oaks are infected with a stem canker disease, probably Sudden Oak Death. Bet you can’t tell which oaks are infected!

Diseased coast live oaks in Portola Valley, CA respond to fire mimicry

29 10 2018

Slide1

Last year I treated four diseased coast live oaks in Portola Valley using a fire mimicry protocol. Here are the results. Three of the four diseased oaks are showing improvement in canopy greenness and fullness. One treated oak is not showing much change in the last year. Note that the fifth photo in this series is a nearby coast live oak that was not treated. It is showing no noticeable improvement in canopy health.
