Planting timing
When to plant tomatillo
Plant tomatillo on the cited sheets — not on a national calendar month. Regional and season notes 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 stay on the named cards below — not one planting window.

Husk notes live on the tomatillo hub. Timing stays on the cited sheets.
