Street trees in San Francisco respond to fire mimicry

A few years ago I began fire mimicry treatments on several street trees (young mayten and olive trees) in San Francisco. They were not diseased or stressed but the owners wanted to ensure the health of their trees using natural, non-toxic fertilizers and ecologically-based treatments. Now, 2+ years later, the mayten and olive trees are clearly showing more vibrant, lush canopies. It is interesting to me that even street trees can be aided with fire mimicry treatments.
