Guide to growing oregano indoors

Growing oregano indoors is a great way to enjoy the fresh herb all year round. You’ll never want for fresh herbs for your pizzas or sauces ever again! There are definitely some important care considerations for growing oregano indoors.

  • Plant oregano in a sunny spot with well-draining soil.
  • Amend the soil with compost or well-rotted manure to improve drainage and fertility.
  • Space plants 8-12 inches apart or in their own personal containers.

Growing oregano from seed

Start by selecting a high-quality oregano seed. We always recommend heirlooms and organic seeds! Sow the oregano seeds indoors in a pot filled with well-draining potting soil. Sprinkle the seeds over the surface of the soil and lightly press them into the soil. Place the pot in a warm, sunny location, such as a windowsill or under a grow light. Keep the soil moist but not soggy by watering when the top inch of soil feels dry. I use a spray bottle when watering seedlings so I don’t disturb their growth.

Once the seedlings have germinated and are several inches tall, begin fertilizing once a month with a liquid fertilizer. When the plants are several inches taller, pinch back the tips of the stems to encourage bushier growth. Harvest the oregano leaves when they reach the desired size. The flavor of the leaves will be most intense before the flowers open.

Companion plants for oregano

It is definitely possible to grow other herbs alongside oregano indoors. Many herbs can be successfully grown indoors, such as chives, thyme, parsley, basil, and sage. Many of these can even be planted in the same pot as the oregano, as long as it is large enough and has good drainage. Additionally, oregano and other herbs prefer the same temperature and light levels, so they can easily be grown together in the same location. With the right care and attention, you can have a variety of fresh herbs growing in your own home all year round.
