When to plant turnips
Plant turnips on the cited sheets — not on a national calendar month. Regional dates stay source-specific.
Growing guidance is general information. Timing, spacing, and care depend on cultivar, weather, soil, and local conditions. Check the sources and adjust the plan for your garden.
Spacing lives on the turnips hub. Timing stays on the cited sheets.
