As a new hopeful land steward of my modest 17 acres in Indiana, USA, I know that there are perfect native plants, that feed the entire ecology of the land, for any area and any type of soil that has not been decimated by construction or other human activities. Mother Nature rules the planet in perfect natural harmony. I must learn her rules and go along with them; I must test the soil so if I add plants (which will only be native for environmental reasons- see Doug Tallamy's watershed work and books), they need to be those selections that are suited to that type of soil. Thank you for an excellent video. Before this, I tried that water-in-the-jar method and not only did that not work, but now it seems rather gross there in the jar after hearing you speak so well about the minute composition of soil. Can't wait to dump that.
