Plan repeat planting dates, harvest dates, crop cycles, seed needs, and garden bed rotation timing. Use a first planting date, planting interval, number of plantings, days to maturity, harvest length, frost date, and seed count per planting.
Planting schedule mode:
The calculator starts with your first planting date and adds the planting interval for each repeat planting.
Fit season mode:
The calculator estimates how many plantings fit between your first planting date and last possible planting date.
Harvest schedule mode:
The calculator adds days to maturity and harvest window length to each planting date.
Seed needs mode:
The calculator multiplies seed or seedling needs by the number of succession plantings and adjusts for germination and extra seed.
A succession planting calculator helps plan repeat sowings so crops do not all mature at once.
It can help build a planting calendar, estimate seed needs, plan steady harvest windows, avoid late plantings that will not mature before frost, and organize garden bed turnover.
Your result shows planting dates, harvest start dates, harvest end dates, plantings that fit the season, first and last harvest dates, seed needs, seedling needs, germination-adjusted seed count, extra seed, and bed turnover timing.
Succession planting means planting the same crop or a replacement crop in repeated intervals so harvests are spread out instead of happening all at once.
Many fast crops are planted every 7 to 14 days. Slower crops may use 21 to 30 day intervals depending on growing space, maturity time, and harvest goals.
Count backward from your first fall frost date using days to maturity and a harvest buffer. Plantings after that date may not mature before frost.
Yes. The calculator estimates harvest start and end dates for each planting, which helps plan steady harvest windows and bed turnover.
No. This is an estimate. Actual timing can vary by weather, crop variety, soil temperature, sunlight, watering, pest pressure, and local growing conditions.
