We grow tall corn! Donna cannot reach the ears and I barely can. Too tall, in fact, because it creates all sorts of difficulties for crop care and harvesting. When the ears are more than 7 feet above the ground and the top of the plant above 14 feet high, the wind in a thunderstorm can really cause a lot of damage. These very tall plants are difficult to harvest since the corn header must process so much more crop material. And...the resulting heavy crop residue makes primary tillage tough to do. We now try to order varieties that do not grow so tall.
