Sweet corn vs survival corn
The corn you eat off the cob fresh is sweet corn — wonderful, but it doesn't store. Dent (field) corn and flint corn are the storage crops: you let them dry hard on the stalk, shell the kernels, and keep them for a year or grind them into cornmeal and grits. For food security, this is the corn that matters.
Plant in a block, not a row
Corn is wind-pollinated, so a single long row pollinates poorly and you get gap-toothed ears. Always plant corn in a square block of at least 4 rows so pollen falls across the whole patch. This one fact fixes most first-time corn failures.
The Three Sisters
Corn, beans, and squash are the classic companion trio: corn gives the beans a pole, beans fix nitrogen for the heavy-feeding corn, and squash shades the ground and blocks weeds. It's one of the most efficient survival-garden layouts ever devised.
🔎 How to identify it
- Tall single grass stalk with broad strap leaves
- Tassel (male flower) at the very top; ears (female) lower on the stalk with silk
- Dent corn kernels show a dimple ('dent') on top when dry
⚠ Lookalikes & safety
Similar tall-grass look; corn's ears-with-silk and top tassel are unmistakable. None dangerous.
