Growing your own herbs can be a rewarding and practical addition to your garden or kitchen windowsill. One popular and versatile herb is oregano, appreciated for its aromatic flavor and low-maintenance growing requirements. If you’re considering adding oregano to your herb collection, it’s essential to know how much space it needs to thrive.

Oregano is a hardy perennial plant that can reach up to two feet in height and spread about 18 inches across when given the right conditions. To ensure healthy growth, it’s recommended to plant oregano eight to 10 inches apart in your garden or container (The Kitchn). Providing adequate spacing allows for proper air circulation, minimizes competition for resources, and helps to prevent the spread of diseases and pests.

Oregano Basics

Oregano is a versatile and popular herb, often used in Italian, Mediterranean, and Mexican cuisines. It’s not only valued for its flavor but also for its ease of cultivation. Growing oregano in your garden or in containers is a simple process as long as you provide it with the proper conditions and space.

One of the key factors to consider when growing oregano is the spacing between plants. According to The Kitchn, oregano should be planted 8 to 10 inches apart. This ensures that the plants have enough room to grow and spread, covering an area up to 18 inches across and reaching up to two feet in height.

When deciding to grow oregano in containers, The Spruce recommends using 6-inch pots, which will allow the plant to develop a more trailing habit compared to those grown outdoors in the ground. This smaller spacing is ideal for indoor growth as it requires less space while still allowing the plant to thrive.

Aside from spacing, other factors that contribute to successful oregano growth include:

  • Planting in well-draining soil
  • Providing plenty of sunlight (at least 6 hours daily)
  • Watering moderately, allowing the soil to dry out slightly between waterings
  • Pruning and harvesting regularly to encourage new growth and prevent the plant from becoming too woody

By paying close attention to the proper spacing and growing conditions, your oregano plants will have the opportunity to grow healthily and provide you with a bountiful harvest of this flavorful herb.

Spacing Requirements for Oregano

Indoor Growing

When growing oregano indoors, it’s essential to provide enough space for the plant to thrive. Start by choosing a suitable container that allows for ample room for root growth. A pot with a diameter of at least 8 inches should suffice for a single oregano plant. Make sure to place the pot in a well-lit area, as oregano requires full sunlight for optimal growth.

While planting multiple oregano plants in one container, maintain a spacing of around 8 to 10 inches between each plant. This will ensure that they have enough room to grow and spread without competing for nutrients and water.

Outdoor Growing

For outdoor oregano gardens, proper spacing is also crucial. Oregano plants can grow up to two feet tall and spread about 18 inches across, so it’s necessary to provide enough room for each plant to thrive without overcrowding them (The Kitchn).

When planting oregano outdoors, it is advised to maintain a spacing of 8 to 10 inches apart between each plant. Additionally, allow for at least 18 inches of space between rows to accommodate the spreading nature of oregano (The Old Farmer’s Almanac).

In conclusion, the proper spacing for growing oregano, whether indoors or outdoors, is vital for the plant’s growth and overall health. Ensuring adequate room for the plants to expand and spread will result in healthier, more flavorful oregano and a more successful harvest.

Factors Affecting Oregano Growth

Soil Type

Oregano thrives in well-draining, fertile soil with a pH around 6.0 to 7.0. Adding compost or organic matter to the soil can improve its quality and promote better growth. Some varieties can tolerate slightly acidic or alkaline soils, but it’s important to check the specific needs of your oregano variety before planting.

Sunlight Exposure

Providing adequate sunlight is crucial for the healthy growth of oregano plants. They require at least 6 to 8 hours of direct sunlight per day. If you’re growing oregano indoors, try to place the containers near a south-facing window or under artificial grow lights to ensure the plants receive enough light for optimal growth and flavor. The Spruce recommends seeds be just slightly pressed into the soil, as they need light to germinate.


Watering oregano plants requires consistency and moderation. Overwatering can lead to root rot and other issues, while underwatering may stunt growth. It’s essential to allow the soil to dry out between watering sessions, as this encourages a strong root system. The frequency of watering may vary based on factors like climate, soil type, and plant size.

When it comes to spacing, oregano plants generally need around 8 to 10 inches between them to grow well (The Spruce). Container-grown oregano requires a pot that is about 12 to 18 inches in diameter for adequate space(wikiHow). Taking all these factors into consideration helps ensure the successful growth and care of your oregano plants.

Common Growing Issues

While oregano is generally easy to grow, there can be some challenges that gardeners may face when cultivating this popular herb. In this section, we’ll discuss common growing issues, focusing on pests and diseases.


Oregano plants may sometimes be affected by various pests. These troublesome critters can weaken the plant and hinder its growth. Common pests that feed on oregano include:

  • Aphids: Small, sap-sucking insects that can cause yellowing and curling of the leaves.
  • Spider mites: Tiny, spider-like pests that cause stippling and yellowing of the leaves, often leaving webs on the plant.
  • Whiteflies: Small, white insects that cluster on the undersides of leaves, causing them to become discolored and limp.

To control these pests, it’s essential to maintain a clean and healthy garden. Removing dead leaves and debris, using organic insecticides, or introducing beneficial insects like ladybugs can help manage pest populations.


Oregano can occasionally be affected by certain diseases that may stunt its growth or ruin the quality of the leaves. Some common diseases affecting oregano are:

  • Root rot: Caused by overwatering and poorly drained soil, this can lead to the yellowing and wilting of the plant, resulting in its eventual demise.
  • Powdery mildew: A fungal disease that results in a powdery, white mold on the leaves, reducing the plant’s vigor and potentially harming flavor.
  • Leaf spot: A fungal or bacterial infection causing brown, yellow, or black spots on the leaves, which can defoliate the plant if left untreated.

Preventing diseases is critical when growing oregano. Ensure proper spacing between the plants to promote airflow, avoid overwatering, and choose disease-resistant varieties when possible. Regularly inspect your plants for signs of infection and promptly address any issues to maintain a healthy oregano crop.

Additional Tips for Growing Oregano Successfully

Choosing the right location is crucial for growing oregano. Plant oregano in an area that gets full sun, as this herb thrives in warm air and soil (Growing in the Garden). Make sure to plant oregano seeds or transplants in well-draining soil.

If you’re starting from seeds, begin the process inside about 8-10 weeks before the last frost date (Growing in the Garden). Press the seeds slightly into the soil without covering them completely, as they require light to germinate (The Spruce). Transplants should be planted at the same depth they were growing in their container.

When spacing the plants, consider the following recommendations:

Keep in mind that oregano plants can grow to be 8-24 inches, depending on the specific species (Kellogg Garden Organics). Support structures are generally not necessary for these plants.

Lastly, while oregano doesn’t require much fertilization, ensure that it receives enough water during the growing season. Be careful not to over-water, as this can lead to root rot or other issues.


In summary, providing adequate space for oregano plants is essential to promote healthy growth and optimum yields. Oregano typically requires a space of 12 to 24 inches between each plant to allow for proper air circulation and avoid overcrowding, depending on the specific variety. Remember that oregano varieties like Syrian oregano (Origanum maru) may grow taller and require a container of at least 2 gallons or more to accommodate their extensive root system.

If you’re planning to grow oregano indoors, it’s also important to ensure the right conditions for successful growth. A water-based (hydroponic) system is an excellent option for achieving this, as it offers consistent access to nutrients and water year-round.

Keeping in mind the specific requirements of oregano plants, such as watering frequency and soil type, can contribute to a bountiful harvest. As a general rule, it’s best to water your oregano only when the soil feels dry, as the plant doesn’t demand as much water as some other herbs (Asia Farming).

Taking the time to learn how to properly space and grow your oregano plants will lead to a satisfying and rewarding experience in your garden or kitchen. By adhering to these guidelines, you can enjoy fresh, fragrant oregano for various culinary creations and seasoning blends throughout the year.
