Papaya plants are native to Central America and Mexico, although they now grow all over the tropical and subtropical world, according to California Rare Fruit Growers. Papaya plants aren't actually trees, they're giant herbs with treelike structure. They grow 10 to 33 feet tall, and their fruit is produced from the terminal part of the papaya plant, also known as the main trunk. Reducing the height of a papaya plant can also reduce its fruiting capacity.
Remove the dead leaves from the papaya plant to reduce fruit scarring, pest infections and disease.
Cut the terminal trunk on the papaya plant back to the desired height with pruners.
Cut back all but two of the remaining shoots. These will be the new fruiting part of the papaya plant.
