Myicorrhizae is a beneficial fungi that helps move nutrients from the soil to the roots. Youtube has several video’s describing how to develop the fungi using super soil, worm castings and oats in a dampened closed mix for about 90 days. The video does not discuss the use for bonsai’s, if any. They appear to infer that pot growers opt for in in their soil preparation.
Has any contact in your area developed “micro” using the above method or buying the fungi from a commercial source and if so when is it used, how is it used and on what species should it be used on?
