What is wrong with my corn?

Poor pollination or fertilization failure (due to pollen tube failure, desiccated and nonfunctional silks, nonviable pollen) can be primarily related to warm temperatures and insufficient water supply during flowering.

Should I cut the tassels off my corn?

How do you increase corn pollination?

Corn: Pollination

Once silks have emerged and the tassels have opened and are dropping pollen, simply shaking the plants will improve pollination.
You can hand pollinate by snapping off a tassel and wiping it on the silks so the pollen makes good contact with the silks.

Why do they cut the tops off of corn stalks?
