What Is Companion Planting?

Companion planting is the strategic placement of different plants in close proximity to each other in the garden, where they can mutually benefit from pest control, pollination, nutrient uptake, and overall growth enhancement.

A lot of gardeners, myself included, use companion planting to repel insects instead of harsh chemical treatments.

Why Oregano Is A Good Companion Plant

Oregano serves as an excellent companion plant primarily because it secretes substances from its roots and leaves that repel various garden pests, such as aphids and cabbage moths, thereby offering a natural form of pest control.

Furthermore, its strong scent can mask the odors of neighboring plants, making it harder for pests to locate their targets.

Additionally, oregano attracts beneficial insects, including pollinators like bees and butterflies, which are vital for the pollination of many crops.

This herb also requires similar growing conditions to many popular garden vegetables and herbs, making it easy to integrate into a diverse garden without competing for resources.

Therefore, incorporating oregano into your garden not only enhances the health and yield of your plants but also promotes a more balanced and sustainable ecosystem.

Known for its robust flavor and numerous culinary uses, growing oregano at home can be a rewarding experience.

Growing oregano is easy following these steps; from from selecting the right variety to troubleshooting common issues.


Choosing the Right Variety of Oregano

Before jumping into planting, it’s super important to pick the right type of oregano.

Think about what kind of flavor you’re after and how each variety grows to make sure it fits with what you want and your garden’s vibe.

Types of Oregano

  • Common oregano Origanum vulgare is the most common type of oregano and is mainly found on the Mediterranean coast.
  • Greek oregano Oreganum heraclites is the most common type of oregano in Greece and is also known as Oreganum vulgare. It has oval and pointed leaves, and produces purple or white flowers from July to September.
  • Mexican oregano This variety has an earthier flavor and scent than other oregano.
  • Cuban oregano This plant has large, succulent-like leaves with a velvety texture and a menthol-ish smell.
  • Wild Greek oregano This robust herb has been used in sauces and marinades since ancient times

Planting Location and Soil

Oregano is a genus of subshrubs and herbaceous perennials in the mint family. It prefers dry, rocky, shallow, and poor soils.

  • Oregano thrives in well-drained soil and requires at least six to eight hours of sunlight daily.
  • Choose a location with good air circulation to prevent diseases.
  • Plant oregano in soil that is rich in organic matter and has a slightly alkaline pH between 6.0 and 7.0.

Propagation of Oregano

Oregano can be propagated from seeds, cuttings, or by dividing established plants.

For beginners, starting with nursery-grown plants or cuttings provides a quicker and more reliable method.

Plant seeds or cuttings in the spring after the last frost, ensuring they are spaced about 12 to 18 inches apart.

Watering and Fertilizing Oregano

Oregano prefers slightly moist soil, but it is susceptible to root rot if overwatered.

  • Water the plants deeply when the soil feels dry, and always water at the base to prevent fungal issues.
  • Apply a balanced fertilizer during the growing season, but avoid excessive nitrogen, which can compromise flavor.

Troubleshooting Common Issues With Growing Oregano

Yellowing Leaves

  •  Cause: Overwatering or poor drainage.
  •  Solution: Allow the soil to dry out between waterings and improve drainage.

Drooping or Wilting Plants

  •   Cause: Lack of water or intense sunlight.
  •   Solution: Water consistently and provide shade during the hottest parts of the day.

Powdery Mildew

  •   Cause: humid conditions and poor air circulation.
  •   Solution: Prune overcrowded branches, improve air circulation, and apply a fungicidal spray.

Leggy Growth

  •  Cause: Insufficient sunlight.
  •  Solution: Move the plants to a sunnier location or prune to encourage bushier growth.
