I have not read every post in this thread, so this may have been mentioned ? It sounds like you have several airplanes in your hangar, and the one that is giving you trouble with your flying field and the corn surrounding the field is the 4 star. If the corn presents that much of a problem with you flying it there and your concerned about it, just don't fly that particular plane until the corn is harvested. Fly the others if they are easier to land. The corn will be harvested in October ? Don't risk your prized plane due to a forced "bad" landing.
I too fly in a similar situation like you do. Corn everywhere 6-7 ft. tall. Every year they alternate between beans and corn. Have to plan my approaches so do not run out of runway and damage the plane due to coming in higher and faster.
