More photos showing a surgery on a stem canker infection in a coast live oak

Here are a set of photos showing a surgical procedure on a coast live oak in Santa Cruz, CA infected with a stem canker disease (probably Sudden Oak Death).

They all received compost tea, soil minerals, and limewash, and some of them also had stem canker surgeries. Here are the results, a pretty decent recovery IMO after only one year, under drought conditions …
