How to Grow Oregano

Last Updated: November 13, 2022 References Approved

Oregano is an herb commonly used in Italian dishes. It is a hearty plant that provides lovely ground cover in addition to its uses in the kitchen. It can be grown both in your home and outside, which means that no matter where you live, with a little time and care, you could be enjoying fresh oregano of your own.

Part 1 of 3:

Determining Your Method for Growing

1
Choose between seeds or clippings. Oregano can be grown from seeds or clippings, so if you already have some oregano plants, you may want to use clippings instead of buying new seeds. When using seeds, you can generally expect that roughly ¼ of the seeds won't grow, so you may want to plant several.^{[1]

- Clippings should only be taken from established plants. You should wait until the roots of your plants are well developed and new growth begins appearing before taking clippings.^{[2]

2
Select your planting location. Oregano is a plant that loves sunshine and soil that drains well, so you should choose a planting location that has these two features. If you live in a colder part of the world, you may want to start your plant indoors and transfer it outside when the weather warms up.
- Oregano grows best in moderately fertilized soil. It's unlikely that you'll need to add compost or fertilizer for it to grow well. ^{[3]

Plan extra space for multiple plants. A fully grown oregano plant will be about 2 to 2½ ft tall (61 to 76 cm) and about 2 ft wide (61 cm). For best results in your garden, you should give your oregano about 10 in (25 cm) of space between plants.^{[4]

- If you plan on growing your oregano indoors, choose a pot that is about 1 ft (30.5 cm) in diameter. This way your plant has adequate room to grow.^{[5]

Plant early for a head start. You can plant your oregano as early as 6 to 10 weeks before the last predicted frost of spring.^{[6]
X
Research source} However, in colder regions or during a cold snap, you may want to protect your plants with a layer of hay.^{[7]

Research source}
- In place of hay, you can also use bed sheets, blankets, or plastic sheeting. To prevent damage to budding plants, you can use stakes to prop up your covering.
- Once the sun has risen and the air warmed, you should remove your covering from the plants. When using hay, you should remove it from covering the plants after the last frost.^{[8]

Planting and Caring for Your Oregano

1
Plant your oregano. You'll want to plant seeds about ¼ inch (.64 cm) deep and bury clippings ½ inch (1.3 cm) deep. You should be patient while awaiting your plants to emerge from the ground since seeds often sprout slowly, though indoor planting may see seeds sprout in less time.
- You should avoid attempting to use seeds that have been stored long periods of time. As time passes, the chance the seeds will grow decreases.^{[9]
  X

- Strip cuttings of their leaves on the end being planted.
- Plants usually take 5 to 10 days to sprout from the ground. However, your oregano may take more or less time depending on factors like soil quality, sunlight, and frequency of watering.^{[10]

2
Water your oregano moderately. During the first few months of growth, water your plants regularly to get them started. Once they are established, you can reduce the amount of water. Check whether your plant needs water or not by touching the soil around it. If it feels dry, you should thoroughly water the area.^{[11]
X
Research source}
- Plants in containers should be treated similarly to outdoor grown oregano. However, when watering, you should douse the plant until you notice water dripping from the drainage holes in the bottom of the container.^{[12]

3
Trim your oregano for thicker growth. By trimming or pinching the leaves and ends of your plant, you can encourage the growth of denser leaves. Wait until the plant is about 4 in (10.2 cm) tall, and use a pair of shears or scissors to lightly thin the outer growth.
- Trimming also helps prevent excessive stem growth in your plant. This condition, called legginess, will reduce the yield of your crop.
- Where you trim your plant, you should notice it branch at that point when it continues growing. In turn, these branches will bear more leaves, meaning more oregano for you.^{[13]

  Research source}
- As you trim, you can use the fresh oregano in a recipe, or dry it to use later on.
4
Remove older plants. Sick or thin plants can crowd better ones and steal resources, negatively impacting the potential of the healthier plants. Plants that are three or four years old are at the end of the oregano life cycle and will be less productive, making these prime candidates for removal.^{[14]
X
Research source}
- You may not remember which plants are old and which are young. In this case, you should wait until early spring when you should be able to judge the plant's age by its initial growth.^{[15]

5
Weed around your plants. Weeds can steal valuable nutrients from your oregano, block out the much needed sun, or soak up the water intended for your plants. Try to target weeds when young, as these will be easier to remove at that time. Grasp the weed firmly at its base with firm, steady pressure, and try to pull up as much of the roots as possible.^{[16]
X
Research source}
- There are many garden tools you might use to assist in your weeding endeavors. A spade or rooting tool could make your weeding less of a chore.
6
Pick your oregano. Oregano can be used fresh from the garden, though you should wash it first to rinse off dirt, bugs, and bacteria. Allow the washed herb to air dry or pat it dry with a towel. Now it's ready to be used in any recipes that call for fresh oregano.
- Oregano reaches peak potency right before it blooms. Blooming season is usually in early July, though this may vary depending on the region you live in.^{[17]

Drying Your Oregano

1
Gather your oregano. The easiest time for you to do this is in the morning after the sun has risen and evaporated any dew. Use a pair of shears or scissors to cut leafy bunches free of the plant, leaving a portion of the stem remaining. Then, gather the bunches into small bundles and use a rubber band around the stems to fasten the bundles together.^{[18]

Research source}
- Try not to bundle the oregano together too densely. This can cause uneven drying and could result in a less than desirable finished product.
2
Cover the bundles. This will prevent dust from accumulating on your oregano as it dries and will keep the sun from bleaching the color from the plant. Paper bags work well for covering your bundles, but you should cut slits in these bags to promote airflow so the herb dries better.
- You should keep an eye on your oregano while it is drying. Direct sunlight can sometimes cause moisture to build up in the bag, which could cause mold to grow and ruin your dried oregano.
3
Hang the bundles to dry. The time it takes to dry will depend on your climate. In some regions, it may take a few days, others may take as long as two weeks. You'll want to hang your plants in an area that is warm and dry, but out of direct sunlight. Some places you might consider for drying your oregano include your attic, porch, a clothesline, or even in your kitchen.
- If you plan on drying outside, you should keep an eye on the weather. Rain could spoil your hard work.
4
Store your dried oregano. When the leaves have become brittle, it's ready to be stored. Lay out a sheet of wax paper and place your bundles onto it. Then you should crumble the plants and pick out the stems, which can be thrown away. Store your dried oregano in an airtight jar, and enjoy it throughout the year.
- To easily transfer your dried oregano into a container, you might want to take the wax paper by two corners and form a funnel with it. Place one end of the funnel above the mouth of your container and tap the paper to shake the dried leaves into it.

You can use it for many years if it stored properly, but it will lose a lot of its flavor after one year. For best results, store dried oregano in an airtight container and put it in a cool, dry place.

No, marjoram is a different but closely related herb. Both oregano and marjoram have several different varieties. They can be used in the same ways and also dried the same way.

Warnings

Do not use pesticides on your oregano unless these are specially formulated to be used on edible plants.
