I dont think they grow together but they grow at the same time in the beginning.

my friend told me people used to do this back in the day, it would make the roots strong and thicker supposdly, making the tree bigger.

of course nowadays they probably have all thats contained in the corn in a natural plant feed.

it may be the gluten, or the proteins/amino acids found in the corn, plus the sugar.

would enzymes help plants grow also?
