Spring and fall leaves under seasonal shade

Plan cool-season leaf crops around a summer shade or heat interruption.

Clear the spring lettuce when quality declines. Leave the bed unplanted through unsuitable conditions and restart only in the fall window.

How to use this plan

Leave a deliberate gap between spring and fall leaf crops.

  1. Check your starting point Record spring quality decline, summer shade or heat, and the return of suitable fall conditions.
  2. Choose the next action Keep the bed empty during the unsuitable gap; use the fall window only after reassessing light.
  3. Carry out the plan Finish lettuce, clear the bed, control weeds during the gap and re-mark arugula when fall conditions fit.
  4. Keep a useful record A two-season map with an explicit unplanted interval.

Square bed spacing is the selected compact planting method. Container spacing describes root positions; foliage may spread beyond the pot. Seed quantities include 10% spare, with 2 small seeds per target and one bean seed per target. Follow cultivar packets if their spacing or sowing instructions differ.

Planting windows

Soil and weather decide the actual planting day.

2027-04-03 to 2027-04-17

Leaf lettuce · spring-leaves

Direct sow. Avoid heat and bolting; sow only in workable soil.

2027-08-08 to 2027-08-22

Arugula for young leaves · fall-leaves

Direct sow. Sow for leaves in cool weather; rapid flowering means the leaf crop is ending. Clear the preceding crop completely first.

Complete first: spring-leaves-1-clear.

From planting to clearing

Estimated cycles fit.

These are planning windows. Record what actually happens in your season journal; clear the space before starting the next crop.

spring-leaves · Leaf lettucePhase 1 · batch 1
  1. Sow2027-04-03 to 2027-04-17

    Avoid heat and bolting; sow only in workable soil. Plant only when the seed packet and local weather conditions agree.

  2. Seedlings2027-04-09 to 2027-05-01

    Mist the surface gently; small seeds must not be washed away. Thin toward 32 positions at 305 × 305 mm when true leaves appear. Keep stronger seedlings. Re-sow gaps only when temperatures and remaining season are suitable.

  3. Tend2027-04-10 to 2027-06-15

    Check the growing center and take small outer leaves without uprooting the plant. Check moisture, surviving plants, weeds, support and visible crop stage; adjust to rain, heat and drainage.

  4. Harvest check2027-05-18 to 2027-07-07

    Pick usable outer leaves before bitterness or a flowering stalk develops. The 45–60-day range begins at direct sowing; check the cultivar and actual crop. Record what is actually ready; this estimate is not a yield guarantee.

  5. Clear / review2027-07-10 to 2027-07-10

    Remove spent plants and check the soil before a successor starts. 21 harvest days and 3 clearing days are planning allowances; actual crop condition decides the changeover. Record actual harvests or losses. Keep healthy perennial clumps if you are not reusing their space; revise the next planting accordingly.

Assumptions and sources

  • Spacing is for the selected compact planting method; follow your cultivar packet where it differs.
  • Seed allowance and minimum root-space limits are planning choices, not germination or yield guarantees.
  • Dates are preparation windows, not forecasts. Confirm soil temperature, weather and actual crop stage.
  • First fall frost is a conservative planning boundary, including for hardy crops. Continuing beyond it needs suitable local guidance and protection.
  • Harvest and clearing durations are planning allowances. A successor waits for the final preceding batch to clear; actual crop progress may move those dates.

Fall plans use a 14-day buffer beyond estimated maturity. Successors wait for the final preceding batch, including its harvest allowance and clearing period. The lifecycle shows those crop-specific windows; the zone must actually be empty. Minimum sun and root-space thresholds are planning limits, with cultivar and climate variation.
