Overview

Oregano forms a low mound of aromatic leaves and summer flower clusters. Culinary strength varies widely by species and cultivar, so a correctly labeled plant matters.

It shares lavender and sage's preference for sun and drainage, making it a poor roommate for moisture-loving peppermint in the same small container.

How to plant oregano

  1. Choose a sunny site with free drainage.
  2. Plant the crown at soil level.
  3. Shear lightly after flowering to keep the mound compact.

Growing from seed

  • Press tiny seed onto moist mix.
  • Provide bright light and bottom water carefully.
  • Thin or pot up before seedlings interlock.

Growing in containers

Use an 8–12 inch pot with gritty mix and full sun. Do not combine it with herbs that demand constantly moist soil.

Harvest, dry and store

Harvest

Cut leafy stems just before many flowers open, leaving several inches for regrowth. Small harvests can continue through the season.

Drying

Hang small bundles or dry stems in a single layer. Strip crisp leaves and discard coarse stems.

Storage

Store leaves whole in an airtight jar away from light; crumble at cooking time.
