Plan your tomatoes 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.
Asheville, Winston-Salem, Roanoke, Nashville, Little Rock. Average last spring frost April 15, first fall frost October 15 — a 183-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.
Set transplants deep — bury two-thirds of the stem to encourage adventitious roots. Stake or cage before fruit set.
Plant near: basil, carrots, onions
Keep away from: brassicas, corn, fennel
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.
