When to plant rosemary
Plant rosemary on the cited sheets — not on a national calendar month. Start methods 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.

Evergreen and container notes live on the rosemary hub. Timing stays on the cited sheets.
