Last September (2020) I treated 8 mature coast live oaks in Soquel, CA, with fire mimicry. We first pruned and cleared around the oaks, which was documented at the time in this post “Initial stages of fire mimicry in Soquel, CA”. We then spread compost tea and alkaline-rich minerals to the surrounding soils, and applied limewash to the trunks of the oaks. After one (drought) year, all 8 of the oaks are showing improvement in canopy density and lushness. Note that in Case No. 20200927.6 (below), this oak is severely infected with a stem canker disease (probably Sudden Oak Death) but is still showing a slight improvement in canopy health.

So exciting to see the documented results! Thanks, Lee, for this life saving work David
