Cut a stem from an existing oregano plant. Place the clipping in a wet sand mixture and allow it to form roots.
Transplant the oregano plant into the garden or container once the roots form. If placed in an outdoor garden, place mulch around the plant to maintain moisture and provide some cover for the winter growth. Plant one oregano plant about every 24 inches in well-drained soil. Select an area of the garden that receives full sun.
Clip leaves of oregano for use before the plant blooms in late summer. New leaves form in the clipped areas within two weeks. The more leaves clipped from the oregano plant the bushier the plant becomes. Properly cared for the plant will grow again the following year.
