Oregano

Origanum vulgare · Herb

A tough Mediterranean herb with a warm, peppery aroma. It thrives on poor, dry soil and full sun; rich soil and too much water weaken the flavor. Once established it comes back for years.

When?

Plant young plants in spring after the last frost. Seeds can be started indoors 6–8 weeks before the last frost (estimated).

Step by step

Sow the tiny seeds on the surface and press lightly; they need light to sprout.
Keep at 65–70 °F; seedlings appear in 1–2 weeks.
Plant out in the sunniest, driest spot you have.
Water only when the soil has dried out.
Trim stems regularly to keep the plant compact.
For the best flavor, harvest just before flowering.
Cut back hard in early spring and divide every 3–4 years.
