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: 1,208.2 L theoretical × 1 allowance = 1,208.2 L; minus 0 L owned = 1,208.2 L net. Buying 1,240 L leaves 31.8 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 1208.2 L of raised-bed growing mix before allowance. Check the actual loose rooting depth below the surface. Keep roots clear of stones and compacted layers.
  • A (Short carrots): keep this zone clear; confirm seed or seedling availability and 5+ hours of sun.
  • B (Small-root beets): keep this zone clear; confirm seed or seedling availability and 5+ hours of sun.

  • Check moisture by touch in each active root zone; adjust watering to rain, heat and drainage. Containers may need checks between weekly visits.
  • Direct sow: Short carrots in A. Choose a short-root cultivar for this depth; loosen soil and remove stones.

12Review and plan ahead2027-06-17 — 2027-06-23To do
  • Check moisture by touch in each active root zone; adjust watering to rain, heat and drainage. Containers may need checks between weekly visits.
  • A: Check a sample root for cultivar size; loosen soil before lifting rather than pulling hard. Maturity estimate 65–80 days from planting is a planning range; observe the crop before harvesting.
  • B: Test one root for desired size; avoid waiting for every root to become oversized. Maturity estimate 50–65 days from planting is a planning range; observe the crop before harvesting.
  • 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.
