The main thing to keep in mind when you apply mycorrhizae is that it only takes one spore to infect the whole root system, so we can say that there’s not really a right and wrong way to apply it so long as you can come up with a way of making sure that at least one comes in to contact with the roots. That’s the other thing too – It must come in to contact with the roots to activate.
In this post I used TNC MycorrHydro as the mycorrhizal fungi, this gives the added benefit of inoculating with bacteria as well as trichoderma at the same time.
The substrate was a blend of TNC Worm Castings and coir
