Why should an observation distinguish older leaves from newer leaves?
Distinguish older and newer leaves when recording where a visible change appears.
Locate the observation on the plant
A record that says “yellow leaf” can lose useful context. Note which part of the plant was observed and whether the affected leaf appears among older growth or newer growth. Add a whole-plant photograph so another reviewer can locate it. Do not use that position alone to identify the cause.
A simple numbering or positional description can make repeated checks clearer. Keep the identifier with the same leaf while it remains present. If a leaf falls or is removed, record the event instead of assigning the identifier to a different leaf without explanation.
A concrete location note
- Example: mark the observed leaf by its position on the whole-plant photograph.
- Record the visible change and date separately from the age description.
- At the next check, confirm that the same leaf is being compared.
