Plan your blueberries 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.
Wilmington NC, Columbia SC, Atlanta, Dallas, Norfolk. Average last spring frost March 28, first fall frost November 5 — a 222-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.
Rabbiteye varieties fit Zones 7–9; southern highbush for Zones 8–10. Soil pH 4.5–5.2 is non-negotiable — amend with elemental sulfur.
Plant near: azaleas, rhododendrons
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.
