Estimate when your garden crops may be ready to harvest based on planting date, days to maturity, germination time, transplant age, harvest window, succession planting interval, and first fall frost date.
From planting mode:
The calculator adds days to maturity to the planting date to estimate the harvest start date.
From seed start mode:
The calculator adds germination days, transplant age, and days to maturity to estimate harvest timing from the seed starting date.
From transplant mode:
The calculator uses the transplant date and days to maturity to estimate harvest timing.
Succession mode:
The calculator creates repeat planting and harvest dates using your succession interval and number of plantings.
A harvest date calculator helps estimate when vegetables, herbs, flowers, and garden crops may be ready to pick.
It can help plan harvest windows, compare planting dates, avoid fall frost problems, organize succession planting, and estimate whether a crop has enough time to mature.
Your result shows estimated early harvest date, harvest start date, harvest end date, days until harvest, days before frost, last safe planting date, and succession harvest dates if repeat plantings are included.
Add the crop’s days to maturity to the planting date or transplant date. For seed-started crops, include germination time and indoor growing time if needed.
It depends on the crop and seed packet wording. For direct-sown crops it often starts from sowing or emergence. For transplants it often starts from transplanting outdoors.
A harvest window is the period when the crop may remain harvestable. Some crops are picked once, while others produce over several days or weeks.
Compare the estimated harvest date with the first fall frost date. Leave a frost buffer so the crop has time to mature before frost risk increases.
No. This is an estimate. Actual harvest timing can vary by weather, crop variety, soil temperature, sunlight, watering, seed age, transplant shock, and local growing conditions.
