Water corn at the base, because if you soak the leaves it washes away the pollen and diminishes the number of kernels you get.
Squirt vegetable or mineral oil (I would think horticultural oil would work too?) into the tip of each ear when the silk appears to kill corn earworms.
Pick it right before you cook it, because the sugars in the corn start to turn to starch as soon as you pick it.
If you find a whitish gray blob on your corn, it's a fungus called corn smut but it won't hurt your corn. It is, however, a delicacy in Mexico called huitlacoche, or "Mexican Truffle". Fascinating!
