Do avocado leaves really help to produce fruit?
My husband bought a 6' tall avocado tree 3 years ago but never produces any fruit. This is the only avocado tree in the neighborhood. I keep the soil moist but its leaves get burned once in a while because it was planted in a sunny spot. My husband insists that I should leave the burned leaves/or pest infected leaves underneath the tree so that the tree gets the nutrition from itself to produce fruit. He believes that regular fertilizer is to help the tree grow only but it won't produce fruit without the nutrition released from the leaves above the ground.
I've searched all over the gardening websites but found nothing about the leaves nutrition. Does anybody know avocado leaves can do the magic like this?
