Seed packets give sowing times as weeks before the last frost, which is useless until you write your own frost date down and count back from it. This chart puts that date at the top, next to your zone or region and the first frost date for the autumn, then gives you a row per crop: the crop, the variety, the date to sow indoors, the date to transplant outside, the days to maturity from the packet, and a notes column for heat mats, soaking or light.
Filling it in is the planning. Work through the seed box one packet at a time, convert each "start 6 to 8 weeks before last frost" into a real date, and the sowing weekends space themselves out instead of landing all at once in March. The days-to-maturity column tells you later whether a crop will finish before the first frost, which decides what is worth sowing in a short season.
Choose 18 roomy rows for handwriting, or 26 tighter rows if you grow a lot from seed. Every cell is a form field, so you can type the chart up, print it for the potting bench, and keep a copy for next year with the notes you made about what germinated and what sulked. One page, US Letter or A4.
