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.
