i agree, undisturbed and healthy soil with natural microbes and mycelium produce healthy disease resistant plants, I actually took some soil from a local wild uncultivated area to add to my seedling compost when I first decided not to dig, this
was like a kickstart for more natural conditions, and tiny fungi pop up in many areas of my garden now. Healthy undisturbed soil add in a few of the local flora, a log pile and a pond and all the beneficial insects and other creatures flock in to help keep pests controlled, it takes 3 predators to control one pest. The mycelium extend root capacity, which helps reduce plant stress and disease vulnerability in drought too.
