If you want your oregano (and your other plants) to thrive in your garden, then you might want to consider companion planting oregano with other plants and herbs.

Before we begin discussing the best companion plants for oregano, we’ll first talk about companion planting and its benefits. Then, we’ll discuss some considerations you should think about before beginning companion planting.

After, we’ll go over what some of the best companion plants are for oregano and why they’re the best. Finally, we’ll end with a quick section about some plants you should avoid using as companion plants for oregano. 

What Is Companion Planting?

Companion planting, in a nutshell, is when you plant two compatible plants near one another in a garden.

By placing two companion plants together or near one another in the garden, they’ll be able to help one another grow.

Overall, it’ll make gardening easier for you in the long run, and your plants will grow more easily.

However, there’s more to companion planting than meets the eye. This process means that you need to strategize where you’ll place your seeds in your garden.

In addition, you’ll need to research how all of your plants grow. For example, you’ll need to know the growing conditions for each when it comes to sunlight, water, soil, fertilizer, and more. 

For instance, some plants will thrive alongside others, making companion planting work. But, on the other hand, some plants might hinder the growth of others.

When done well, there are plenty of benefits of companion planting for you, your garden, and all of your plants.

What Are The Benefits Of Companion Planting?

So, why should you bother with companion planting? There are many benefits to using this method in your garden, as it’ll allow all your plants to grow well and thrive.

A few of the benefits are as follows:

  • Unwanted pests will stay away
  • Pollinators may be attracted to your garden
  • Boost flavoring and coloring
  • Shade regulation
  • Weed control

To explain further, oregano has a strong scent. So, some pests are repelled by it, which will keep your other plants safe. On the other hand, some pollinators are attracted to it, which will help the other plants grow.

Also, oregano can spread out. The less room in the soil means there’s less room for weeds to grow. However, you’ll need to be mindful about not overcrowding your garden to ensure that the plants can grow well, too.

In addition, oregano can shade other plants from the harsh sunlight if that’s not what they need. Finally, oregano can help boost the coloring of other plants, thus enhancing their flavor.

What To Consider When Looking For Oregano Companion Plants?

When pairing plants together, you want to make sure they have similar needs to grow well. So, let’s take a look at some of the things to consider when companion planting with oregano. 

Growing Conditions

One thing to note about finding companion plants for oregano is to know how to grow each plant.

For example, oregano thrives on sunlight. So they’ll need a spot in the garden where they can get the most sun during the day.

So, you’ll want to choose a plant that might also need sunlight. Or, since oregano grows relatively tall, you can plant something that doesn’t require a lot of sunlight behind it. Then the oregano will shield the other plant from the light.

Water is another growing condition. Oregano doesn’t need a lot of water and doesn’t like to be moist most of the time. In fact, you’ll only need to water your oregano once the soil is bone dry.

If other plants require a lot of water or like the soil to be moist, then you can be sure they won’t make for a good companion plant for your oregano.

Finally, oregano does well on its own without the use of fertilizer. So, plants that don’t need fertilizer will do well near oregano.

Size Of The Plant

One of the reasons companion planting is good for your garden is that some plants will help one another grow well.

However, if you have a massive plant beside a smaller one, there’s a chance the bigger plant will take over. Thus, it’ll grow over the smaller plant and backfire on the small plant’s growth.

Believe it or not, Oregano can take up a lot of room.

For example, oregano can grow about two feet tall and spread out about two feet wide.

It’s easy for oregano to get out of control and take over larger areas if given the room to grow.

Luckily, oregano can do its job as a companion plant when it’s not directly sitting in the garden beside others.

So, you can plant oregano in a pot within your garden to not overtake any other plants. However, it’ll still be able to do its job of being a companion plant.

For instance, the oregano will still have a strong scent to attract pollinators and keep pests away. 

Best Companion Plants For Oregano

Oregano, for the most part, gets along well with many plants. However, some other plants or herbs thrive with oregano nearby.

So, what grows well with oregano? Here’s what to plant with oregano. 

Sage

Sage has similar growing conditions to oregano, so the two will do well near each other.

For example, sage prefers its soil to be dry. So, you can water both plants lightly at the same time. If the two of them are beside one another, a little water will absorb and spread through the soil.

So, you might only need to water a little bit, and it’ll reach both plants.

Thyme

Thyme is similar to both sage and oregano. In fact, you can probably place these three herbs together in the garden.

This particular herb also doesn’t like heavy watering, so you can be sure that you can lightly moisten the soil around this herb, and together, thyme, sage, and oregano will get the water they want and need.

Rosemary

Rosemary is part of the oregano family. Thus, it has similar needs. For example, rosemary doesn’t like too much water either.

Not only can you place this herb with oregano and a few others like it, but you can even plant rosemary and oregano together in the same pot.

Basil

Basil might be difficult to pair with oregano, but it’s not impossible. Once you better understand how to grow oregano and how companion planting works, you can certainly try pairing basil and oregano together.

It might be difficult to put basil with oregano because there are a few types of basil. Some basil has the same watering needs as oregano, but other types of basil prefer to have moist soil.

So, whether you can pair basil with your oregano or not will depend entirely upon which type of basil you have.

Lavender

Lavender and oregano help one another out. Oregano will help lavender grow well, and lavender has the same soil needs as oregano.

So, the two together will be peas in a pod, helping each other grow well. 

Tomatoes

Tomatoes are another great option to put beside oregano. While this fruit needs more water than oregano, tomatoes can dig their roots deeper. Therefore, they can get more moisture.

So, you can water the two together lightly, and tomatoes can dig for extra water under the surface while keeping the oregano dry.

Cucumbers

Cucumbers, unfortunately, are victims of a few different types of pests. Oregano, luckily, will repel these pests away with its scent which make these a great combination.

Grapes

Like cucumbers, grapes also have many pests that will come for them. But, thanks to oregano’s scent, these pests won’t want to go near the oregano or the grapes.

Squash

There are bugs known as squash bugs that will eat the squash in your garden before you get the chance to harvest it and try it for yourself.

These bugs don’t like the scent of oregano, so the herb will be able to repel these bugs from your squash.

Zucchini

Zucchini is in the same boat as squash. Certain bugs will be attracted to this veggie, but the scent of oregano will keep them away.

Cauliflower

This veggie is another one that may suffer from bugs and other pests. However, with this scent once again, oregano can repel these pests.

So, your cauliflower will be able to grow well around oregano.

In a nutshell, oregano does a great job at keeping pests and other bugs away. One of the upsides is that you won’t need to worry about using pesticides in your garden.

Instead of keeping bugs away by using chemicals and possibly damaging your food, the oregano will do the job for you naturally. 

Plants To Avoid As Companion Plants For Oregano

Now that we know that oregano prefers not to have heavy water, you’ll want to avoid putting oregano near plants that need a good drink.

For instance, oregano can do well with many plants, including vegetables, flowers, and other herbs. However, some veggies prefer lots of water, prefer growing in the cold, or can overtake much of the garden.

For example, the following plants won’t make great companion plants for oregano.

  • Cabbage
  • Broccoli
  • Collards
  • Celery
  • Lettuce
  • Mint
  • Chives
  • Cilantro

That’s just to name a few. Also, oregano can stand up well in colder weather, but you don’t want to plant oregano beside plants that grow better in the cold.

In addition, some plants like to take over. For example, mint is one of them. Mint is an invasive plant and, if given the room, it’ll take over quite a bit of the garden.

So, if you’re going to grow mint, your best bet is to put it in a pot or far away enough from the other plants so it can grow well without disturbing the other plants.

Oregano itself can spread out pretty well, but mint will overtake the oregano.

Finally, some plants, such as cilantro and chives, need plenty of water to grow and thrive. Since oregano doesn’t like too much water, it would be all too easy to accidentally overwater the oregano or not provide enough to the other herbs. Thus, stunting the growth of one of the plants.
