Containers with mix already owned

Reuse 40 L of suitable potting mix before ordering bags for a 60 L setup.

Inspect stored mix and use it only if suitable for containers. Enter usable volume, not weight in kilograms.

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.

Your first twelve weeks

Check off each week as you work.

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.
