Common questions
When should I plant oregano?
Oregano is a hardy perennial in zones 5-10 and is easiest to start from seed indoors 6-8 weeks before the last spring frost, or from divisions or cuttings; seeds are tiny and slow to produce harvestable growth. Transplant outdoors around the last frost date once soil has warmed to at least 13 °C — established plants tolerate light frost. In zones 4 and colder, treat as an annual or overwinter divisions in a cold frame; in zones 9-11 it stays evergreen but may die back in intense summer heat without afternoon shade. Because the right window depends on your local frost dates, pick your US state above for a calendar with exact sow, transplant, and harvest dates.
Does the best time to plant oregano vary by state?
Yes — planting dates swing by several weeks across the US because each state sits in a different USDA zone with its own frost window. Every state page here gives oregano dates calibrated to that state's climate.
How are these oregano planting dates calculated?
Each state's dates come from that state's dominant USDA hardiness zone and NOAA average frost dates, then adjusted for oregano's cold tolerance and days to maturity.
