Sorry for the hijack: After a plant is harvested by clipping at the base, would the undisturbed fungal network die off, leaving only these fungal and bacterial spores? In other words, the fungal hyphae isn't going to be re-animated. It's dead like a dead plant stem I assume. Anything that comes back to life is coming from spores after a month, maybe.
how long a period before a new plant is planted? decpomposing(saprophytic) fungi will still be intact. the mycorrhizal fungi might die off and go to spore if you took to long to get a new root system going.
