I guess I was thinking more about hydro, where you change your nutrients often. I imagine it would be much less often for soil.
Opie Yutts Reviewed by Opie Yutts on . Mycorrhiza I was in a nice store the other day a noticed they had a bag of Mycorrhiza. When i used to work in a tree farm we always knew about it. However, it was very specific to the tree. I remember one time I took a caterpillar tractor out and very carefully lifted the top 4" of soil up so it could be loaded up and transferred to another location so they would be more able to grow the same trees we were growing. It was all about the mycorrhiza. Apparently it is in the top 4' of the soil. My question Rating: 5
