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.
