Figure 5. Preparation of spores for infection.

Divide the spore-clay mix into subfractions, according to the number of trays (six), the number of pots (nine), and the number of plants in each pot (five), by using a razor blade. C. Pick up one pile per plant using the bent end of the pipe cleaner. Note that for picture B and C, only clay was used to visualize the different steps of the subfractions.
