That was field horsetail and lime. It required 4 specific conditions to run wild, and
I provided them all:
*Kill all of it's competition
*Have soggy soil
*Have a lower pH
*Have excess free potassium
This is what that cocktail got me:. It was really an amazing feat. I grew such a tremendous crop of horsetail, I was able to create a crop canopy with a plant that has no leaves.

It slowly started to click when I was doing some experiments to try to stimulate acorn production in mature bur oaks. I spread a full 50 pound bag of lime under the canopy of each tree. It must have been a high dose, because you could see the exact line where the lime was spread, because the fern and horsetail vanished. This is one of many observations that led me to get rid of all my sprayers, chemicals, and fertilizers. Once I quit the potions, my problems went away.
