Below is a time-lapse video of a stem canker surgery we did today on a pollarded, Ohlone “ancestor” coast live oak in Portola Valley, CA. Note the removal of diseased tissue with axes and power multi-tools, cauterization, and poultice application. This was followed by a limewash application to the trunk, as well as compost tea and alkaline-rich mineral amendments to the soils. Enjoy!
