San Francisco has already badly missed the point on trees once, and now it looks like they may be doing it again.

In Part 1 I talked about the history of Bio Char. In Part 2, I discussed some of the controversy surrounding this soil amendment.

And once we start talking to folks about sticking a product like the Silva Cell underneath the sidewalks where their utilities run, some people would love to stop the conversation altogether. But using the Silva Cell in areas with utilities isn’t… More
