Plan your sweet corn planting around local frost risk and soil temperature, then work backward from the harvest week your buyers need. The calendar below is a starting point, not a field-level weather forecast.
Raleigh, Greensboro, Richmond, Knoxville, Memphis. Average last spring frost April 8, first fall frost October 22 — a 197-day frost-free season.
Windows are calculated from your zone's average frost dates. Adjust ±1 week for microclimates, elevation, and your own frost records.
Plant in blocks of 4+ rows for wind pollination. Isolate super-sweet varieties from standard varieties by 250 ft or 14 days.
Plant near: beans, squash, cucumbers
Keep away from: tomatoes
BAU Farm Intelligence turns these windows into per-field tasks — indoor seed-start reminders, transplant dates, harvest projections — using your farm's actual frost history.
