Question: Why does my corn keep flopping over?

Google’s answer:

Corn plants with floppy corn syndrome often have visible seminal roots but poorly developed or no nodal roots. When exposed to strong winds, these plants can fall over because they lack the support of nodal roots. The wind can also break off nodal roots, making it difficult for the plant to establish a permanent root system.
To diagnose floppy corn, you can dig up a plant that isn’t standing upright and gently remove the soil to examine the roots. If your corn is leaning, you can try staking it up temporarily. You can also try tamping down around the roots or watering at the base of the plant to fill in air pockets and push loose soil around the roots. Corn stalks often straighten themselves out within a week, especially if they aren’t too heavy and haven’t tasseled yet.

I thought I had planted my corn deep enough but I will have to try planting deeper next time, water deeply, as well as pack the soil.
