Calculate seed sowing and planting dates in seconds with this even handier version of the Handy Seed Starting Chart.

- Download the seed starting chart file. If you don’t have excel, you can download a free open-source office suite with a spreadsheet application at openoffice.org or Google Docs.
- Enter the “Frost Free Date” for your region in the yellow box at the top. See almanac.com
- Before you can say, “Presto chango” the spreadsheet will quickly calculate all sowing and planting dates and place them in the appropriate fields.
- Print your chart and hang near your seed starting set-up or tape it into your garden journal. It is that easy!
You can also download a do-your-own-math PDF Seed Starting Chart for the mathematically inclined.
