Third update on my small property.
I'm incorporating biochar-rabbit poo mix into a raised bed front yard orchard by coring out sections around the trees with a post hole digger and filling those spaces with the mix. I think this may be the best bet to incorporate the Biochar at the root level for already established trees.
Let me know what you think.
