Planting timing
When to plant garlic
Plant garlic 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.
Dates and soil notes stay on the named cards below — not one planting window.
Sow on the cited sheet. Spacing lives on the garlic hub.
Types and spacing live on growing garlic.
