The Ultimate Guide to Planting and Growing Oregano
Are you a fan of flavorful Mediterranean dishes? If so, you’ll likely appreciate the robust, earthy taste of oregano, scientifically known as Origanum vulgare. This bushy, woody-branched perennial is a member of the mint family, Lamiaceae, and is a popular herb used in various cuisines for its aromatic flavor.
If you enjoy cooking Italian-American dishes like pizza, grilled meats, dressings, and sauces, you’re probably familiar with oregano. In fact, Americans consume over 14 million pounds of oregano every year, highlighting its widespread popularity.
Embrace the Mediterranean Flavor
Oregano hails from the Mediterranean region and the Middle East, where it thrives in warm climates. It grows to be one to two feet tall and two feet wide, producing oval, fragrant leaves and delicate blooms in pink, lavender, or white during mid to late summer.
This versatile herb is hardy in USDA Zones 5-10 and can even be grown as an annual in colder regions. So, let’s explore how you can cultivate this flavorful herb in your garden and enjoy its culinary benefits.

While oregano is often confused with marjoram due to their similar names, it’s essential to recognize their botanical differences. Marjoram is a separate species known as O. majorana, distinct from oregano’s O. vulgare variety.
Additionally, other herbs like Mexican oregano and Cuban oregano share common names but belong to different plant families. Mexican oregano is Lippia graveolens, while Cuban oregano is Plectranthus amboinicus, each offering unique flavors and scents.
Cultivation and Historical Significance
With its origins in Greece, oregano holds a rich history dating back to ancient Greek civilizations. Dubbed the “joy of the mountain” by the Greeks, oregano symbolized joy, good luck, and health, and was often grown near homes to ward off evil spirits.
Romans recognized the culinary value of oregano and carried it across the lands they conquered. However, it wasn’t until American soldiers returned from World War II with a taste for Italian cuisine that oregano found widespread popularity in the US.
Plant Propagation Made Easy
If you’re eager to grow oregano in your garden, you have several propagation options to choose from:
From Seed
- Directly sow seeds outdoors once temperatures reach 70°F – Place seeds on the soil surface without covering – Thin seedlings to 8 inches apart after germination – Consider starting seeds indoors for early growth
From Cuttings
- Take 4-5 inch stem cuttings in spring – Remove lower leaves and place in water or soilless mix – Transplant rooted cuttings after 4-5 weeks – Keep in a bright location away from direct sun
Through Division
- Divide plants in spring or fall when the soil is warm – Separate plant root balls into multiple sections – Replant divisions in pots or a different garden area
Growing Oregano: A Flavorful Journey
Similar to vacationers in Cabo San Lucas, oregano loves full sun and well-drained soil with a neutral pH. This low-maintenance herb tolerates hot, dry conditions and requires minimal watering, making it ideal for both garden beds and containers.
Oregano can serve as a ground cover, border plant, or rock garden accent, providing culinary and ornamental value. To encourage bushy growth, trim or harvest leaves regularly, especially before the plant goes to seed in late summer for reseeding.
Tips for Successful Growing
- Opt for full sun exposure – Avoid overwatering to prevent root rot – Regularly trim plants to maintain a bushy form – Allow flowering to produce seeds for future growth

Combatting Pests and Diseases
Although oregano is generally resistant to pests and diseases, a few common issues to watch for include:
Insects
- Aphids: Use water blasts or insecticidal soap – Leafminers: Control with neem oil spray – Spider Mites: Treat with neem oil and monitor for webbing
Diseases
- Mint Rust: Look for pustules on leaves and treat with fungicide – Severely infected plants may require removal and disposal
Harvesting and Preserving Oregano
Once plants are at least 45 days old, begin harvesting leaves or sprigs for culinary use. For long-term storage, dry oregano leaves using a dehydrator or by hanging stems in a cool, dry location.
Store dried leaves in airtight containers away from light and heat to preserve flavor. Alternatively, infuse oregano into oil for diverse culinary applications like salad dressings or bread dipping.
