Oregano in Zone 9a & 9b
Origanum vulgare
When to plant oregano in zone 9b
Zones 9a and 9b share the same average frost dates in our data, so this page covers both.
Method: Start indoors: Start indoors from seed, then transplant outside. Oregano needs a head start most zones can't give it by direct-sowing alone.
| Start indoors | Dec 21–Dec 28 |
|---|---|
| Direct sow / transplant outside | Feb 22–Mar 1 |
| Estimated harvest | May 13–May 20 (~80 days after transplanting) |
Spacing: 4 per square foot (square-foot-gardening spacing). Mature height: 1-1.5 ft.
Oregano is a low, spreading perennial in the mint family, and one of the more forgiving herbs you can grow. It performs better in lean, dry soil than in rich, well-watered beds.
How oregano fits zone 9's season
Zone 9b's frost-free window runs about 293 days, from February 15 to December 5. Oregano needs about 80 days from transplant to first harvest.
