Tool + guide bundle
IdunSeed
Keep a seed inventory and sowing dates relative to your chosen frost date.
You keep seed packets and want one place that turns “start 8 weeks before last frost” style intervals into real dates, shows which packets are running low, and prints this week's sowing tasks.

How it works
Download and extract your bundle
Buy the IdunSeed bundle at /store/idunseed/ and extract idunseed-0.1.1-guide-bundle.zip. Then extract program/idunseed-preview-20260929.zip into a separate folder. The app/, extension/, samples/ and docs/ paths below refer to that extracted program folder. GUIDE.html and examples/ in the outer bundle contain this manual and its practice material.
Put it into Google Sheets
Open drive.google.com and upload app/IdunSeed.xlsx. Right-click it, choose Open with › Google Sheets, then File › Save as Google Sheets so you work in a native Google Sheets file. Keep the original .xlsx as a clean copy. Sheet labels are in English with Russian underneath.
Set your last frost date
On the Settings sheet type the year, month and day as three whole numbers in B3, B4 and B5. B6 shows the computed date; B8 shows a message if the date is impossible. The template ships with the sample date 2028-04-15, which is valid, so nothing warns you until you change it.
Before you buy
- A Google account and Google Sheets in a web browser. The .xlsx file is only the way the template travels; Excel and LibreOffice are not supported targets.
- Your own last frost date and the intervals from your seed packets. IdunSeed contains no weather data and gives no gardening advice.
- The purchased idunseed-0.1.1-guide-bundle.zip download. It contains program/idunseed-preview-20260929.zip; the program itself is unchanged from the earlier release.
Extract the bundle, then the original program ZIP in program/. Upload app/IdunSeed.xlsx to Google Drive, open it with Google Sheets and save it as a Google Sheets file. Read the included instructions first.
Compatibility & limits
Planning template only; not weather or agronomic advice. Google Sheets API formula calculations checked; desktop/mobile editing and physical printing unverified.
