How to Plant Oregano? 

Oregano grows easily in most climates and prefers well-drained soil with plenty of sunshine. In this section we’ll discuss how to plant oregano from seed or cutting, when to harvest it, and how to dry it for long-term use.

Planting from Seed

The best time to start growing oregano from seed indoors is about eight weeks before the last frost date for your area so that you can transplant it outdoors when the weather is right. Start by filling small pots with well-draining potting soil and wetting it thoroughly.

Then sprinkle oregano seeds over the surface, adding more if necessary to ensure they’re evenly spaced. Cover lightly with additional soil and wet again. Place the pots in a sunny location, such as on a windowsill or in a greenhouse, and keep them moist but not soggy for about two weeks until germination occurs.


Once you have at least four inches tall seedlings, it’s time to transplant them into your garden bed or container of choice. Dig holes that are twice as deep and twice as wide as the size of each plant and place them in full sun. Firmly pack the soil around each plant and water thoroughly.

Oregano requires regular watering to grow its best. Water your oregano plants every few days or when the top inch of the soil feels dry. Do not overwater, as this can cause rot and disease in the roots.


Fertilize your oregano only once in spring with a balanced fertilizer such as 10-10-10. This will ensure that your herbs get the nutrients they need to thrive without overfeeding them, which can cause damage to their delicate leaves.


When you’re ready to harvest your oregano, wait until its stems are at least six inches long, then snip them off with scissors. You can also leave some stems on the plant to ensure that it continues to grow and remain healthy.


The best way to preserve your oregano is by drying it. To do this, tie several stems together at the base and hang them upside down in a cool, dry place away from direct sunlight until they’re completely dry. Then store the dried herbs in an airtight container in a dark cupboard or pantry for up to one year.

How to Care for an Oregano Plant?

The oregano plant is a hardy, drought-tolerant perennial herb that can be grown in many climates. It’s an easy herb to care for and adds flavor and color to your garden. Here are some tips on how to take care of your oregano plant:

  1. Plant in Well-Drained Soil: Oregano prefers well-drained soil with a pH between 6.0 and 7.5; if the soil is too damp, it may cause root rot. Add plenty of organic matter, such as compost or manure, when planting oregano in the garden bed; this will help the soil retain moisture without staying soggy.
  2. Give Plenty of Sunlight: Oregano loves the sun and should be planted in an area that receives at least 6-8 hours of direct sunlight daily. If you’re growing oregano indoors, a south-facing window is ideal.
  3. Water Regularly: While oregano is drought tolerant and does not require frequent watering, it’s important to keep the soil evenly moist but not soggy. When deciding how much to water your plant, stick your finger into the soil; if it feels dry up to your first knuckle, it’s time to give the plant a drink. Water until it runs out of the bottom of the pot or irrigation tray; this will ensure that all the roots get an adequate water supply.
  4. Feed Every Month or So: Most oregano plants can do with general-purpose fertilizer once a month, but if your plant is looking a bit pale or isn’t growing well, you can give it an extra boost of nutrients with a liquid fertilizer. Be sure to follow the directions on the package carefully; too much fertilizer can burn the roots and damage your plant.
  5. Prune as Necessary: Keep your oregano plant tidy by pruning off any dead or dying branches and any straggly stems that don’t fit in with the plant’s overall shape. This will also help keep it healthy and encourage new growth.

Following these tips can keep your oregano plant happy and healthy for many years. Enjoy the fragrant, flavorful leaves in all of your favorite recipes!

Preventions from Pests and Diseases:

  1. Inspect your oregano plant regularly for signs of pests and diseases, such as aphids, whiteflies, rust fungi, or powdery mildew.
  2. Remove any affected leaves with scissors or pruning shears and dispose of them in the garbage.
  3. If the problem persists, treat your oregano plant with insecticidal soap or fungicide according to the instructions on the package.
  4. Keep your oregano plant well-watered and mulch around it to help prevent problems from occurring in the first place.
  5. Avoid planting different varieties of herbs together; some can be susceptible to similar pests and diseases, so it’s best to keep them separate.

These steps will help keep your oregano plant healthy and free of pests and diseases. Enjoy the delicious flavor it adds to all your favorite dishes!

How to Harvest Oregano?

  1. Harvest oregano when the leaves are large enough to use, usually about two months after planting.
  2. Cut off individual stems with scissors or pruning shears just above a leaf joint just like Rosemary herb .
  3. Collect the cuttings in a basket and place them in the shade until ready to use or store them for later use.
  4. The flavor of dried oregano is more intense than fresh; spread out your harvested oregano on a baking sheet lined with parchment paper and let dry at room temperature for several days before storing it in an airtight container away from heat and sunlight.
