He does have a video that addresses soil; I just haven't gotten to that one yet...he has another one where he rates seed catalogs, and I was proud to note that I have four of the five. :-)
He gave this catalog an 'honorable mention' for all the fans of fruit trees and shrubs...worth checking out.
I have the One Green World catalog. It has lots of unusual varieties of fruits, nuts, bamboo, etc, and they are good strong plants, packed very well for shipping. They are, however, very pricey for those of us on strict budgets.
The blood orange I ordered from them 15 years ago is still alive. It’s a bit stunted for a number of reasons, mostly a lack of light, but it survived the time I was laid up with a back injury and couldn’t water my houseplants for over 2 months!
