CHECKS
If the label identifies loose-leaf lettuce and outer leaves are ready: Choose those older leaves for this picking. Keep your record focused on which leaves you removed and what growth remains.

If you planted a heading type for a whole-head harvest: Follow that variety's harvest goal. Do not assume the outer-leaf schedule describes when its head is ready.

If a seed stalk is rising or leaves have become overly mature: Review bolting and crop replacement before planning more pickings. A harvest checklist cannot reset the plant's growth stage.

ACTION CHECKLIST
[ ] 1. Identify the plant and stage
Record the packet name and plant height. Photograph the whole plant so later checks can distinguish new growth from leaves already present.

[ ] 2. Pick and count the outer leaves
Make a small selective harvest rather than applying an unverified whole-plant cutting rule. Write down the number removed and photograph the remaining center.

[ ] 3. Check the container afterward
Record moisture and visible leaf condition. Choose the next inspection from what the plant is doing, not from a promised harvest interval.

NEXT CHECK
At the next visit, count newly usable outer leaves and note any seed stalk. Record a zero harvest honestly if the plant is not ready; compare the photograph before choosing another action.
