Among my herb garden treasures, oregano is one of the most rewarding plants to grow. Every year, I watch my collection of culinary herbs flourish, each supporting my cooking and healthy lifestyle in its own unique way.
Oregano is one of the fragrant herbs that has been doing great all summer and has started to flower in the last few weeks. Tiny clumps of beautiful, vibrant purple flowers adorn this fragrant green plant, attracting many bees. I swear, there is never a second in a day when these blossoms are left alone.
If you’re already a fan of oregano, you know that its exceptional taste blends nicely with French and Italian cuisine. The herb tastes incredible when fresh and dries perfectly.
I’m excited to share more about this incredible culinary herb rich in fragrance and flavor!

How to Grow Oregano
Are you a fan of fresh, fragrant herbs? If so, add oregano to your list and start growing this aromatic herb at home with this simple guide.
Growing
- Oregano thrives in well-drained soil with alkaline pH and full sunlight for at least 6-8 hours
- Add a compost to boost your soil (first things first)
- Sow the seeds indoors in pots, preferably terracotta pots, or directly into the ground
- Press the seeds slightly into the soil, needing room for light to germinate
- Water the soil gently (avoid waterlogging)
- Seedlings will grow in a couple of weeks. Space them about 10-12 inches apart as this herb forms a spreading clump
Note
- If you prefer to grow this plant indoors in pots, transplant the seedlings (once they have 3-5 sets of leaves or 11-15cm tall) into larger pots or ground by digging up a hole (as big as the root ball) and follow the above guide
- Once established, regular watering isn’t needed as this plant is drought-tolerant
- You can grow oregano from cuttings by planting them directly into the soil or splitting their clumps
Harvesting and Storing Oregano
Harvesting
I prefer mornings to harvest oregano when their oils are most intense.
Simply snip off the leaves from the stems. The most flavorful leaves occur before the plant blooms in the summer. So, if you plan to take twigs for drying, that’s the best time.
For a big harvest, cut the stems just above the plant’s lower set of leaves; this promotes new growth.
Note: Frequent pruning promotes bushier growth and prevents the plant from becoming leggy.
Storing
Here’s how you can store freshly harvested leaves for future use:
- Air or hang-drying method
- Herbal infusion or decoctions (best for cough and cold)
- Freezing (whole or chopped leaves)
- Ice cubes
- Tincture
How To Consume Oregano
Do you want a restaurant-style taste in your homemade food? There’s no secret to it! Cook with oregano and turn your meals into a five-star dish.
Here’s how you can consume this aromatic and flavorful herb in your dishes.
Dried Leaves
Dried leaves (flakes or grounded) pair well with pizza, pasta dip, tomato sauce, and homemade herbal bread.
Add oregano to your stews, baked chicken, and corn soup, and enhance their taste instantly!
Fresh Leaves
Freshly chopped leaves blend well with sauteed veggies, meat, and green salads.
You can consume leaves in tea, herbal brews, and decoctions.
Tip: Add dried leaves when you begin the cooking process and fresh ones at the end!
