Where you garden
Enter a US zip code and the frost dates fill themselves in. You can adjust them afterwards —
your own records always beat an average.
Your frost dates
Everything on the calendar is worked out from these two dates. Adjust them if you know your
own ground runs earlier or later than the county average.
Saving
The plan saves to this browser automatically. Export a file to keep a backup or move it to
another device — worth doing at the end of a season.

What the plan flags
The plan, in plain words
How the spacing works: each square on a bed is one square foot, and the number in the corner
of a filled square is how many of that plant fit in it at proper spacing. Carrots at three inches
give you sixteen to a square; a tomato at twenty-four inches needs four squares to itself, so the
tool marks all four. That is the arithmetic most people get wrong in April and pay for in July.
On the dates: planting windows are calculated from the frost dates you enter, not from a
generic zone, because two gardens in the same zone can differ by weeks. They are a starting point
rather than gospel — a cold spring pushes everything back, and your own records beat any chart
after a couple of seasons. Archive each year and the rotation checker will start warning you when
a family is about to land where it grew recently.
