Composted manure and many soilless potting mixes contain high levels of phosphate and other nutrients. With a plethora of nutrients, plants are less dependent on mycorrhizal connections. Mycorrhizal fungi retreat into the shadows, remaining inactive until more hospitable soil conditions return. Not surprisingly, this mutually beneficial association between mycorrhizal fungi and plants has been marketed in the form of products that we’re told will improve soil health and plant establishment in gardens and landscapes.

As the hair-like hyphae emerge from the spores, rain and irrigation water create channels down through the soil toward growing plant root tips. Receptive roots release chemical cues that allow hyphae to penetrate the cell walls and create chemical passageways between the two partners. Multiple infection points and hyphal branching create a cottony sheath around the roots that extends far into the surrounding soil. Like microscopic miners, mycorrhizae discover and extract soil water and nutrients from otherwise inaccessible pockets.
