Growing Oregano at Home

Growing from Seeds vs Cuttings

Soil Needs

Oregano thrives in well-draining, slightly alkaline soil with a pH of 6.5-7.5. Enrich soil with compost or organic fertilizer before planting. Container gardens also work well.

Sun and Water Requirements

Sun: Oregano needs at least 6 hours of full sun daily. Partial shade is okay, but can affect flavor intensity.
Water: Wait until the top soil layer dries out between watering. Avoid overwatering which causes root rot.

Ongoing Care

Prune lightly in spring to shape plants and boost new growth. Avoid heavy pruning.
Mulch around plants for moisture retention and weed control.
Container plants need more frequent watering and fertilization. Bring indoors if temperatures drop below 40°F.

And that’s it! With proper soil preparation, sunlight and water.

Harvesting Oregano

You can begin harvesting oregano leaves once the plant reaches 4-6 inches tall.
For maximum flavor, cut just before flowers bloom when oils are most concentrated.
Either clip sprigs lightly with stems attached or individual leaves.
Leave some leaves on the plant for regeneration. Don’t harvest more than one-third from one plant.

Preserving the Herb

There are several ways to preserve harvested oregano for future use:

Drying

The most popular method. Rinse cut sprigs and hang bundled upside down in a warm, dry spot to air dry for 1-2 weeks.
You can also dry leaves on a baking sheet inside an oven on the lowest temp (100°F) for 30 mins.
Store dried leaves in airtight glass jars away from sunlight for up to 1 year.

Freezing

Finely chop fresh oregano leaves, pack with olive oil in ice cube trays and freeze. Pop out cubes to flavor cooking.
You can also place whole leaves between paper towels before freezing in bags. Use within 6 months.

Oregano Oil

Steam chopped leaves, add to carrier oil like olive oil for a few weeks then strain oil. Refrigerate for 3 months use.

Vinegar

Add oregano sprigs to vinegar and steep for 2-3 weeks to infuse flavor. Strain and store in bottles.
