Harvest tracking
How to track your garden harvest
Keeping a harvest log tells you which crops earn their space, when each one really starts producing, and what to plant more or less of next year. Here is what to record and an honest look at three ways to do it.
Why track your harvest at all?
Memory is unreliable by autumn. A simple log turns "the beans did well this year" into real numbers: how much each crop gave, when the first and last pickings were, and which varieties beat the others.
Over a few seasons those numbers start to answer practical questions. Did that extra row of potatoes pay off? Do you need fewer zucchini plants? Is it worth starting tomatoes earlier? You can compare your results against typical figures in our vegetable yield chart.
What to record
Every picking
- Date. Shows when each crop starts and stops.
- Crop and variety. "Tomato, Sungold" beats "tomato".
- Amount and unit. Kilograms or grams for bulk crops, a count for big single fruit.
Once per crop or now and then
- Sowing or planting date. Lets you see days to first harvest.
- Where it grew. Bed, pot or greenhouse.
- Notes. Weather, pests, what you would change.
Notebook, spreadsheet or app?
There is no single best method. The best one is the one you'll still be using in August, so pick the trade-offs that suit you.
Notebook
Good at
- No battery or phone needed
- Easy to add sketches and notes
- Nice to look back on
Watch out for
- Totals and comparisons mean adding up by hand
- Easy to forget in the house
- No backup if it gets wet or lost
Spreadsheet
Good at
- Free, and sums and charts are automatic
- Easy to compare seasons
- You control the columns
Watch out for
- Awkward to fill in on a phone in the garden
- You build and maintain it yourself
- Often updated in batches, so details get lost
Harvest tracker app
Good at
- Log a picking in a few taps where you are
- Totals, timelines and stats per crop
- Notes and harvests in one place
Watch out for
- Needs your phone with you
- Another app to learn
- Your data lives in the app, so check you can export it
A simple spreadsheet layout
If you go the spreadsheet route, one row per picking with these columns is enough:
| Date | Crop | Amount | Unit | Note |
|---|---|---|---|---|
| 2026-07-14 | Zucchini | 3 | pcs | first picking |
| 2026-07-16 | Green beans | 0.4 | kg | |
| 2026-07-18 | Tomato | 1.2 | kg | after rain, some split |
A pivot table on the crop column then gives you season totals per crop. If you switch later, Harvest Journal can import past harvests from a CSV file.
Habits that make logging stick
A common reason people stop tracking is simple: it feels like a chore. These habits keep it to a few seconds per picking.
- Log in the moment. Write it down at the kitchen counter or on your phone right after picking. Batches of "I'll do it later" rarely get done.
- Keep a cheap kitchen scale handy. Weighing the whole basket and noting one total per crop is good enough.
- Count when weighing is a hassle. "6 zucchini" is still useful data.
- Don't aim for perfection. A log with a few gaps still tells you far more than no log.
- Review once at the end of the season. Total each crop, note what to change and you're done until spring.
Using Harvest Journal
We make Harvest Journal, so take this section as our pitch. It's a private garden journal for iPhone and Android: you add the crops you grow, then tap to log each picking by weight or count. It keeps a running total per crop, journal notes and season stats, and works offline without an account. Your data stays on your phone.
If you just want a one-off summary, the free Harvest Report turns a list of crops and dates into a printable PDF in your browser. You can use it with a notebook or spreadsheet log too.
Not sure when your crops will be ready? The harvest calendar and the plant library guides cover ripeness signs crop by crop.

Harvest tracking FAQ
What is the easiest way to track a garden harvest?
Whatever you will actually keep doing. For many people that is a phone app they already carry into the garden, for others a notebook by the back door. Logging the date, crop and amount is enough.
Should I weigh or count my harvest?
Both work. Weigh crops that come in bulk, like potatoes, beans or greens, and count crops that come in units, like zucchini, cabbages, ears of corn or pumpkins. Pick one method per crop and stick with it so the numbers compare year to year.
Is there a free garden harvest tracker?
Yes. A notebook or a free spreadsheet costs nothing. Harvest Journal is free to download, and the Harvest Report on this site makes a free PDF summary of your season in the browser, with no account.
What should a garden harvest log include?
At minimum the date, the crop and the amount with its unit. Planting dates, the variety and short notes about weather or pests make the log much more useful when you plan next season.
