How to check seedlings for fungi
It is probable that some seedlings will have better growth of fungi than others. This inconsistency doesn’t matter because in the revegetation site fungal mycelia will spread widely from infected “nurse plants” to other plants.
Depending on the type of pots and soil mix, it may be possible to lift out the entire soil and plant to observe the sides of the soil. This is the best chance of seeing any fungal growth. Sometimes it may be possible to see fungal threads growing in the potting soil either with the naked eye or with a hand lens. But it is more likely that germinated spores will not have proliferated by the time of planting, and the threads will be difficult to see. Sometimes mycorrhizal roots may be visible, but again most of those are difficult to see with native fungi and native plants.
