@Billtheman Every week I add a small amount to the surface of my pots
making sure that when I water it in , it goes directly to the root system otherwise you may be wasting it
I don't scrimp on Mycorrhizae as I have discovered just how beneficial it is for both plant and soil health
I know that it is quite expensive but well worth the cost and effort in my opinion
Hopefully you keep your great white refrigerated or atleast in a nice cool place as this will keep it in the best condition
All the best Mate with your lovely plants 👌
