Oregano is a versatile herb that is commonly used in cooking, particularly in Mediterranean and Italian cuisine. It adds a unique flavor and aroma to dishes, making it a popular choice for home gardeners. While oregano can be propagated through cuttings, growing it from seed is a rewarding and cost-effective option. In this guide, we will walk you through the step-by-step process of growing oregano from seed.

Choosing the Right Seeds

The first step in growing oregano from seed is to select high-quality seeds. Look for seeds that are fresh and viable, as old or low-quality seeds may not germinate effectively. You can purchase oregano seeds from garden centers, nurseries, or online seed suppliers.

It is also important to choose the right variety of oregano seeds. Common varieties include Greek oregano (Origanum vulgare subsp. hirtum), Italian oregano (Origanum x majoricum), and Mexican oregano (Lippia graveolens). Each variety has its own distinct flavor profile, so choose the one that suits your culinary preferences.

Sowing the Seeds

Once you have obtained your oregano seeds, it’s time to sow them. Follow these steps for successful germination:

  • Fill a seed tray or small pots with a well-draining potting mix. Oregano prefers slightly alkaline soil, so consider adding a small amount of lime to the mix.
  • Moisten the soil before sowing the seeds. This will create a favorable environment for germination.
  • Place the seeds on top of the soil, spacing them evenly. Cover the seeds with a thin layer of soil or vermiculite.
  • Mist the soil with water to keep it moist, but not waterlogged.
  • Cover the tray or pots with a plastic dome or plastic wrap to create a greenhouse effect. This will help retain moisture and speed up germination.
  • Place the tray or pots in a warm location, such as a sunny windowsill or a heated propagator. Oregano seeds require temperatures of around 70°F (21°C) to germinate.
  • Keep an eye on the soil moisture and mist as needed to prevent it from drying out.

Caring for Oregano Seedlings

After about 7-14 days, you should start to see the oregano seeds germinate. Once the seedlings emerge, follow these care instructions:

  • Remove the plastic dome or wrap to prevent the seedlings from becoming too humid.
  • Place the seedlings in a location with bright, indirect sunlight. Oregano requires at least 6-8 hours of sunlight per day.
  • Water the seedlings regularly, keeping the soil evenly moist. Avoid overwatering, as this can lead to root rot.
  • When the seedlings have grown a few sets of true leaves, thin them out to allow more space for each plant to grow. Remove the weaker seedlings, leaving only the strongest ones.

Transplanting Oregano Seedlings

Once the oregano seedlings have grown to a suitable size, usually around 4-6 inches tall, they can be transplanted into their final growing location. Follow these steps:

  • Choose a sunny spot in your garden or prepare a large container with well-draining soil.
  • Dig a hole that is slightly larger than the root ball of the seedling.
  • Carefully remove the seedling from its pot, taking care not to damage the roots.
  • Place the seedling in the hole and backfill with soil, gently firming it around the base of the plant.
  • Water the transplanted seedlings thoroughly to help them establish in their new location.

Harvesting and Pruning Oregano

Oregano can be harvested once it reaches a height of about 4-6 inches. To harvest, simply pinch off individual leaves or cut entire stems just above a set of leaves. Regular pruning will encourage bushier growth and prevent the plants from becoming too leggy.


Growing oregano from seed is a rewarding process that allows you to enjoy fresh, flavorful herbs in your cooking. By choosing the right seeds, sowing them correctly, caring for the seedlings, and transplanting them into their final location, you can successfully grow oregano at home. Remember to harvest and prune regularly to encourage healthy growth. Now, armed with this comprehensive guide, you are ready to embark on your oregano growing journey!
