Observation and action checklist

Lettuce growing a tall stalk: decide what to harvest and replace

Separate bolting from ordinary leaf growth, record the conditions, and plan a replacement batch for a more suitable growing window.

Compare what you can see

The center stretches upward and flower buds appear

Record the stage and decide whether any remaining undamaged leaves still suit your intended harvest. A plan for the next batch is more useful than assuming the plant will return to its earlier leafy stage.

The plant is leafy but tastes increasingly bitter

Review heat, watering and age as well as the center stem. Bitterness alone does not tell you exactly which factor changed.

A replacement must grow through hot weather

Check the variety's season guidance and the actual shaded growing space. A cool-season crop cannot be scheduled solely from an empty bed date.

Your next care visit

Check off what you have reviewed. Use the downloadable sheet to keep your observations.

  1. Write down the sowing date and the stage you wanted to harvest. Decide which plants to harvest now and which space to clear; mark the cleared area so it is not counted as ready while plants still occupy it.

  2. Use a cultivar suited to the intended season. Afternoon shade, suitable mulch and consistent moisture can reduce stress. Divide the next sowing into smaller batches so one weather spell does not affect the whole crop at the same stage.

  3. Open your plan with actual frost information and a realistic new start date. Read the harvest and clearing windows before using the same space for another crop. Keep local temperature and packet guidance alongside the calculated dates.

Keep this in mind

Do not describe a heat-tolerant variety as heat-proof. Do not start a successor in the plan until you know how much space will actually be free.

What to record next

Record the date you clear this batch and the chosen replacement. At the next sowing, compare its cultivar, exposure and timing with this record so the change is deliberate.

  • Lettuce type, cultivar and sowing date
  • Center stem and flower-bud observations
  • Recent heat and moisture changes
  • Harvest decision and area to clear
  • Actual clearance date
  • Next cultivar, sowing window and shaded location
