A garden journal turns memory into evidence. A notebook, binder, spreadsheet, or private photo album all work if you will use them consistently.
For each visit, record some of these:
- date, high and low temperature, rain, frost, and unusual weather;
- a sketch or photo of the plot;
- plant species, cultivar, source, sowing or transplant date, and location;
- germination, first flower, first harvest, and final harvest;
- soil moisture before watering and what you did;
- insects, disease symptoms, wildlife, and any control used;
- compost, mulch, fertilizer, or other input and its measured amount; and
- flavour, yield, show result, surprise, or change to try next year.
Do not force every month into equal lines; June may need pages while January needs one drawing. Label close-up photos with a wider location view, and never include a child's full name or address in a public online journal.
At season's end, mark three things that worked, three that did not, and one experiment for next year. Use the dates to build a flexible Chores Calendar based on plant stages and weather rather than the old sample's fixed days.
