Indoor growing journal
Starting a simple plant journal
Make a first entry
Record the plant's name, where it sits and the date. Add a picture or a quick sketch. This first entry gives you a reference for changes you might otherwise overlook.
Describe changes
Note new leaves, a change in position or a different appearance of the soil. Keep observations separate from guesses about their cause.
Compare like with like
Photograph the plant from a similar position each time. A small, consistent record makes changes easier to see than a collection of unrelated close-ups.
