How to Use This Calculator
  1. Enter the days to maturity from your seed packet and the harvest window — how many days each planting will produce harvestable crops.
  2. Enter your total frost-free growing season length in days and the number of successive plantings you want to make.
  3. Enter the number of seeds or transplants per planting round.
  4. Review the Days Between Plantings to schedule your sowing calendar evenly across the season.
  5. Note Total Seeds Needed and Total Harvest Weeks to plan purchases and estimate continuous supply duration.
