I used to use neem meal in my recipe when I first started but there were a couple times I thought I might have over done it and I think it negatively affected the taste. I was a newbie then. Ive been re using my soil ever since however I have never re-amended neem cake.
I spend a ridiculous amount of money on beneficial insects
I have probably mixed mine is as well but I mostly top dress it now. Like I said, the plants love it topdressed and it's a slow release N source which I like. The fungal growth goes crazy right on the surface.
