Spring Planting vs Fall Planting
Compare spring planting and fall planting by using the correct frost edge, soil temperature, crop tolerance, maturity runway, and protection plan for each season.
What changes by season
- Spring planting
- Use spring planting after local winter cold begins to release, but still separate hardy cool-season crops from frost-sensitive warm-season crops.
- Fall planting
- Use fall planting by counting backward from local first frost, then adjust for heat at sowing, shortening day length, cooling soil, and crop maturity.
- Last frost
- Use the last spring frost date as a cold-risk screen for spring direct sowing, indoor-start timing, and transplant timing. It does not prove soil is warm enough.
- First frost
- Use the first fall frost date to estimate harvest runway, fall sowing stop dates, and whether season extension is worth planning.
Decision workflow
- Start with the right frost edge
- Spring planning starts from last frost; fall planning starts from first frost. Do not copy spring planting dates into fall.
- Check crop season
- Match cool-season and warm-season crops to the season window before choosing a sowing or transplant date.
- Check soil and heat
- Use measured soil temperature for spring readiness, then watch late-summer heat and moisture when starting fall crops.
- Check maturity runway
- Use days to maturity plus germination, transplant recovery, and harvest-quality limits before assigning a spring or fall bed.
- Protect the edges
- Use row cover, low tunnels, cold frames, or other season-extension tools when the crop is worth protecting near frost.
