If you grow your own corn, you can of course harvest baby corn. Baby corn is picked right after the silk of the corn is formed. It’s not farmed often in the US, because it is so small, and not much of a “money crop.” Especially since the demand for baby corn is not high, growing mature corn is usually a more profitable venture for US farmers. Most baby corn available in the US is grown in Asia, where the food is considered of high value and a delicacy.
