Plan your garlic 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.
Charleston SC, Savannah, Mobile, Austin, Jacksonville. Average last spring frost March 15, first fall frost November 15 — a 245-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.
Fall-planted only. Plant 4–6 weeks before first frost so roots establish before soil freezes. Harvest when lower 3 leaves brown.
Plant near: tomatoes, brassicas
Keep away from: beans, peas
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.
