Frost dates and timing in South Dakota
Average last spring frost: early to late May. Average first fall frost: mid-September to early October. Growing season runs about 130-160 days. As always, average dates are starting points — set seedlings out a week or two later than the average last-frost for high-value crops like tomatoes and peppers, and have row cover or frost blankets ready for an unseasonable late freeze.
Use the fall planting schedule by zone to plan your second crop, and the vegetable garden planting schedule for week-by-week spring timing.
