Record the decision and the result, not every detail of every day.
Give every crop a basic record
Write down the crop, variety, planting date, and location. Include whether you direct-sowed or transplanted. Keep seed packet instructions or a reference to them. These details turn a vague memory of a good crop into something you can try again.
Record changes worth comparing
Note unusual heat, heavy rain, missed watering, pest observations, and major changes to care. Photograph the same area occasionally so you can compare growth. A weekly observation can be more useful than a long entry written only when something goes wrong.
Keep harvest units consistent
Choose grams, kilograms, pounds, or item counts as appropriate. Do not add weights and counts into a single total. The harvest log exports the units with each entry so the record stays interpretable. Yield alone is not the whole result: also note flavor, usable quality, and how much work the crop required.
End with three decisions
At the end of a growing period, write one thing to repeat, one thing to change, and one thing to stop. Keep the next plan small enough to act on. A journal earns its place when it changes a decision, not when it becomes another demanding gardening chore.
