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.

Mix: 509.7 L theoretical × 1 allowance = 509.7 L; minus 0 L owned = 509.7 L net. Buying 520 L leaves 10.3 L beyond the net requirement. Allowance is your choice; no fixed compaction loss is assumed.

Your first twelve weeks

Check off each week as you work.

01Prepare and begin2027-04-01 — 2027-04-07To do
  • Check moisture by touch in each active root zone; adjust watering to rain, heat and drainage. Containers may need checks between weekly visits.
  • Measure the usable space. Prepare 509.7 L of raised-bed growing mix before allowance. Three distinct blocks let you thin the roots without disturbing the leaf crops.
  • Direct sow: Leaf lettuce in A. Avoid heat and bolting; sow only in workable soil.
  • A: check surface moisture and emergence without disturbing roots. Mist the surface gently; small seeds must not be washed away.
  • B (Small-root beets): keep this zone clear; confirm seed or seedling availability and 5+ hours of sun.
  • C (Swiss chard): keep this zone clear; confirm seed or seedling availability and 5+ hours of sun.

  • A: check surface moisture and emergence without disturbing roots. Mist the surface gently; small seeds must not be washed away.
  • B: check surface moisture and emergence without disturbing roots. One seed cluster can make several seedlings; clip extras after true leaves appear.

  • Review the next stage: late crops may need care beyond these twelve weeks. Record harvest, failures and remaining supplies before selecting your next planting.

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 editable planning choices, not germination or yield guarantees.
  • Dates are preparation windows, not forecasts. Confirm soil temperature, weather and actual crop stage.

Fall plans use a 14-day buffer beyond estimated maturity. Succession plans allow 7 days after the preceding crop estimate and still require an empty zone. Minimum sun and root-space thresholds are planning limits, with cultivar and climate variation.
