Unsurprisingly, Greek Oregano was originally grown in Greece. It was believed to be created by the Goddess Aphrodite, who denoted it as a symbol of joy (the name is from the Greek words oros and gonos, in entirety meaning “joy of the mountains”).

In this blog, we’ll be talking about everything related to growing oregano outdoors, from the basic facts, supplies, setup, and steps to grow, care for and harvest it, and gardening zones in the US and how they can impact outdoor gardening.

Plant type




Binomial name

Origanum vulgare



Oregano sprouts in 1-2 weeks then they can be harvested from Month 3+ on.

Full sun

Oregano needs an equivalent of 6+ hours of direct sun [DLI of 18+ mol/m²/day]..


Growing oregano outdoors is beginner friendly, but it can involve a few more steps compared to growing it indoors. You’ll sprout, thin, prune, and harvest, and maybe try to get rid of pests and other problems from time to time.


Ways to Grow Oregano Outdoors

Growing Oregano Indoors Using Soil 

Oregano plants, unlike basil, don’t do well in moist soil conditions. The roots are not accustomed to being too wet and will rot in boggy conditions. On the other hand, if the soil dries out completely the roots will die back and the plant won’t recover. This can catch you off guard because the plant’s not very expressive (its leaves don’t wilt) so it will look fine right up until it dies. 

You have two options to choose from when growing oregano outdoors:

  1. plant directly onto soil, or
  2. use a container - with drainage!

If you prefer planting directly onto soil, you can use potting mixes you can buy from stores or online, or you can also create your own. In this blog, we explained how to create your own potting mix. Just remember that even though herbs such as oregano are “Light Feeders” they still need nutrient-rich soil, so if you don’t have that, you can also look into incorporating plant foods or fertilizers.

We prefer using containers as we have more control over the growth of herbs by using this method. iI you opt for containers, they should have good drainage as herbs such as oregano thrive well in this kind of environment.

You can also see the table comparison below about the pros and cons of soil and containers:



Soil (in ground)

  • cost-effective
  • easier set up
  • smaller yield
  • slower germination
  • takes much more space


  • minimal space taken
  • better yield 
  • faster germination
  • minimal supervision needed
  • needs to have proper drainage for the herbs to thrive
  • just need more maintenance overall
  • more expensive


Other Ways to Grow Oregano Outdoors

You can also use ollas (plant watering spikes/globes) for your containers to help with drainage. Raised beds are a good choice for growing herbs such as oregano outdoors, too.

Best Gardening Zones for Growing Oregano Outdoors

Oregano can be grown in most areas as they are sun-loving herbs that can adapt to a wide range of temperatures, but the most recommended zones are zones 4-10.

Care and Maintenance of Oregano Outdoors

Lighting for Growing Oregano Outdoors

Oregano plants are sun-loving herbs, meaning they need lots of light – but since you’ll be growing them outdoors, you just need to make sure that they would be put in a very bright place that gets at least 6+ hours of direct sunshine.

What is The Right Temperature for Your Outdoor Oregano Plant?

Oregano Plants Grow Faster in Warmer Temps

Oregano plants are called “warm-weather crops” and will speed up their metabolism when temperatures are warmer. On the other hand, if things get too hot they’ll wilt and become prone to disease. Ideal temperatures are around 70°F but in anything between 55 and 90°F it grows well.

Water and Humidity: How Often to Water Oregano Outdoors

Herbs such as oregano thrive on adequate moisture but can suffer if they’re waterlogged, so make sure to water them regularly. To avoid your outdoor oregano plant becoming waterlogged, make sure to use a pot with drainage, or just use ollas, as mentioned above.

Nutrients and Fertilizers

Oregano likes to start with nutrients that are equal parts nitrogen, phosphorus, and potassium (with NPK numbers like 10-10-10). For this Balanced Blend we recommend: Dr Earth All Purpose

Once they are growing, it’s better to use plant food that is high in nitrogen (with NPK numbers like 10-5-5). For this Herb Blend we recommend: Joyful Dirt All Purpose

Moving Your Outdoor Oregano Plant Indoors

Oregano mostly thrives in warm temperatures, as we talked about above, so we suggest moving your oregano plant indoors only when the temperature is too cold for its liking. To learn more about how to grow your oregano indoors, check this out.

Timeline and Steps on How to Grow Oregano Outdoors

Best Setup for Outdoor Oregano Plants

Below is the best setup (and a very easy one!) for growing your oregano plants outdoors. You’ll need:


Ceramic Self Watering Planter or a pot that is at least 8″ / 1 gal. Raised beds and ollas can are also great choices.


Free-Draining Mix

Plant Food:

At the start: Balanced Blend. This should be equal parts nitrogen, phosphorus, and potassium (with NPK numbers like 10-10-10). 

Ongoing: Herb Blend. This should be high in nitrogen (with NPK numbers like 10-5-5).

Starting your Oregano: Seed vs Cutting vs Nursery Plant

New Oregano plants can be started from seed, propagated from an established plant, or purchased live at many garden centers. We prefer to sprout from seed or propagate from a stem cutting, as it results in plants that are adapted to your growing conditions and limit the chances that you accidentally bring home pests.)

How to Plant Oregano seeds

Oregano grows quickly from seed. Plant 1 site in an 8" / 1 gal container. In larger containers, space sites 8" apart. For each site press 2 seeds into the surface. Keep the soil warm ( 60-80°F, ideally 70°F). Sprouts typically appear in 12 days but can be as quick as 10 days or as long as 15 days depending on your conditions. Don't cover the seeds as light helps them sprout. 

How to Transplant Oregano

Live starter plants give you a big jump start on your first harvest. When you’re in a garden center - pick the bushiest plant available (tall and lanky ones will be weak growers) and give it a good inspection for pests.

Leaves should be dark green without holes, spots, or curled edges. A best practice is to actually “quarantine” your plant for about a week after bringing it home to make sure it's free and clear of ride-on pests. 

Ensuring it’s pest and disease-free it’s time to transplant your seedling into its final home.

  1. Remove some soil from its final planter - leaving enough space for the bottom of the seedling to be just higher than the soil surface.
  2. Hold on to the base of the stem with one hand, and turn the pot over while gently pulling the seedling. Giving the pot a few squeezes can help dislodge it.  
  3. Place in its final container and fill around it with soil so that it’s tight, but not compacted.  

Week 1-2: Check for Sprouts

You could see seedlings in as little as 10 days (though 12 days is more typical). If it’s been 15 days and you still don’t have any sprouts, it’s likely that your setup is too cold.

Week 4: Thin Your Seedlings

Thin your planter to only have 1 seedling per site -  leaving the largest plant. If you are using the recommended planter (at least 8" / 1 gal) this will mean you’ve got 1 plant after thinning.  By getting rid of the smaller seedlings, you’re allowing the biggest and strongest one to flourish by reducing its competition for water, food, and space. 

If your seedlings are under 1 inch, stretching out, or folding over, it’s likely that they don't have quite enough light.

Month 2: How to Prune Oregano Plants

Once your Oregano plant has 3 sets of mature leaves you’re ready for your prune. Cut off the top set of mature leaves, leaving the bottom two (it’s best to cut right above the pair of leaves you’re keeping on the plant).

Once these branches grow out (and each has a few sets of their own leaves) you can cut the tip - just as you did with the main stem. At this point your plant will be fairly well shaped, so hone your inner Bonzi master and use your thinning and heading cuts to harvest and shape your herbs as you go.  

Month 3+: How to Harvest Oregano

After 4 months you can make a small harvest of stem tips. After 6 months you should be able to harvest bunches. Let the soil dry out between watering.

How to Use Your Freshly-harvested Oregano in Cooking

Oregano is more than just being everyone’s favorite topping on pizza! These pungent herbs with a sweet and almost minty taste can be used in many other ways such as:

  1. Garnish or toppings to various dishes such as pasta, seafood, etc.
  2. Making pesto
  3. Making dips or sauces

How to Preserve Oregano 

There are several ways to preserve or keep your herbs fresh, and here are just some of the easiest and the ones we recommend the most:

  1. Lazy person technique. It involves keeping the fresh herbs in their original packaging and simply storing them in the fridge.
  2. Storing the herbs in a glass of water inside the fridge. You can do this by cutting the end of the stem of your herb, filling a glass jar or cup with water, and placing your herb inside. Almost like a vase or bouquet of herbs!
  3. Keep in a glass of water under natural lighting.
  4. Wrap loosely in a damp paper towel.
  5. Freeze them herbs! Yes, you can freeze fresh herbs such as oregano to use at a later time! All you need are some ice cube trays and a freezer, and you’re all set.
