Sweet corn is a mutation of field corn selected for high sugar content at the milk stage. It is harvested immature and eaten as a vegetable rather than a grain. Modern supersweet (sh2) varieties retain sweetness much longer after harvest than older types.

Consejos de cultivo
Plant sweet corn in blocks of at least 4 rows (not single long rows) to ensure adequate wind pollination and full ear fill.
Isolate supersweet (sh2) varieties from other corn types by 75 m or 2 weeks in planting time to prevent cross-pollination that reduces sweetness.
Harvest at the milk stage when silks are brown and dry; pierce a kernel with your fingernail and milky juice should squirt out.
