4×8 spring salad bed

A salad bed with full-size lettuce and up to three successive radish batches.

Radishes reuse their own zone only after the previous batch is cleared. Later batches can fall beyond twelve weeks; skip repeats in unsuitable summer heat.

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: 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.

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 906.1 L of raised-bed growing mix before allowance. Radishes reuse their own zone only after the previous batch is cleared. Later batches can fall beyond twelve weeks; skip repeats in unsuitable summer heat.
  • Direct sow: Leaf lettuce in A. Avoid heat and bolting; sow only in workable soil.
  • Direct sow: Small round radishes in B. Use a small round spring variety, not daikon; avoid sustained hot weather.
  • 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. Thin early after emergence; a crowded root will not size well.

  • A: Check the growing center and take small outer leaves without uprooting the plant. Compare actual growth with your seed packet; remove competing weeds carefully.
  • B: 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.

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.

  1. UMN Extension: Growing lettuceFull-size leaf lettuce plant distance is 10–12 inches. Our 12-inch square cells use an intensive bed layout rather than conventional row aisles. Accessed 2026-10-04.
  2. UMD Extension: Growing vegetables in containers and salad tablesSun exposure, drainage, growing media and crop-specific minimum volumes; our thresholds are conservative planning settings. Accessed 2026-10-04.
