Cabbage uses a reviewed indoor transplant start profile instead of the former universal six-week default. The local frost date remains editable because cultivar, soil, hardening and microclimate can move the plan.

  • Reference method: indoor transplant start; published lead-time reference: 5–7 weeks.
  • Use the selected spring or fall crop plan and harden seedlings before transplanting.

Context matters.

  • Cultivar, transplant tolerance, germination temperature, hardening and local microclimates can shift the planting window.

Source & calculation QA reviewed

The calculation guide and this source trail show what the result means, where the rule came from and when it was last reviewed. This is source-and-calculation QA, not a claim of medical, legal, tax or other professional review; time-sensitive decisions still belong with the linked authority.
