Planting timing
When to plant parsley
Plant parsley on the cited sheets — not on a national calendar month. Timing stays 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.
Biennial and leaf-form notes live on the parsley hub. Timing stays on the cited sheets.
