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.

Soil and weather decide the actual planting day.

2027-04-10 to 2027-05-01

Short carrots · A

Direct sow. Choose a short-root cultivar for this depth; loosen soil and remove stones.

2027-04-10 to 2027-05-01

Small-root beets · B

Direct sow. Use a small-root variety and workable cool-season soil.

2027-04-03 to 2027-04-17

Small round radishes · C

Direct sow. Use a small round spring variety, not daikon; avoid sustained hot weather.

Mix: 906.1 L theoretical × 1 allowance = 906.1 L; minus 0 L owned = 906.1 L net. Buying 920 L leaves 13.9 L beyond the net requirement. Allowance is your choice; no fixed compaction loss is assumed.

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 906.1 L of raised-bed growing mix before allowance. Remove stones and avoid stepping in the root zones. Direct sow all three crops; thin rather than transplanting extras.
  • Direct sow: Small round radishes in C. Use a small round spring variety, not daikon; avoid sustained hot weather.
  • 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.
  • C: check surface moisture and emergence without disturbing roots. Thin early after emergence; a crowded root will not size well.

  • 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.
  • C: Pull one sample root at edible size; remove woody or flowering plants before another batch. Maturity estimate 25–35 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.
