I just know that when people came out west with say peaches those that had
the soil from home their trees did the best. better than bear root because
they carried the soil life the peaches were using back home.
Amazing. That's an important thing to remember.
So when planting bare root fruit trees then maybe use bacteria
dominated compost + some rock phosphate, azomite, greensand, quarry rock
powders (these will really stimulate earthworm colonization of the
soil; after a while it will look like swiss cheese. Millions of 1/16" to
1/4" holes peppering the surface of the soil. Minimal till with long
intermediate periods of no till produce this.
