my grandfather was a farmer in orlando for decades.
he did his own experiments on plants.
for instance, he made two plots, side by side.
one plot he came out every morning and talked lovingly to it.
told it how he loved it and was so happy to see it growing tall and lush.
(idk what the crop was..)]
the other plot he cursed and screamed at it, daily.

he surprised himself because he had heard plants respond to love and good thoughts towards them.

im sure you can guess the outcome.
the loved plot grew nicely.
the hated plot grew mutated and didnt thrive at all.
he said there was such a marked difference.

btw he also did this experiment on two horses.
the same thing.that horse got meaner and meaner.
it couldnt be around people.

ive never forgotten him telling us this as little girls.
