Enter a US ZIP, state or USDA zone and get exact sow, transplant and harvest dates for 85+ vegetables and herbs. Plus frost dates, flower guides, bulb rules, garden calculators and free printables, sourced from university extension.





Hi Product Hunt! Planting dates are scattered across dozens of state extension pages, each written for its own climate. We built My Planting Calendar to put them in one place: enter a US ZIP code, state or USDA zone (or your own frost dates from anywhere in the world) and get sow, transplant and harvest dates for 92 crops.
What is in it:
Planting windows and succession sowing for 92 vegetables, herbs and a few fruits, plus 69 fruit and nut guides (chill hours, pollination)
Frost dates for every US state, and zone-by-zone dates for 18 flowers with the fall bulb rules each state publishes
Calculators (seed starting, spacing, soil, compost, mulch) and free printable PDFs: a companion planting chart, zone calendars and a flower planner
How we handle the data: every timing rule comes from a university extension page and is linked on the page. Where two states disagree we show both instead of picking one. There is no sign-up. The site is free and supported by ads and a few affiliate links, which are marked next to the links.
What is missing for you? Crops, regions or tools you would want, tell us and we will look at them.
