Why these dates

Step by step

  1. Pick a sunny spot with soil that drains well, and mix in an inch or two of compost.
  2. Plant young oregano plants Apr 15 – Jun 10, 12 to 18 inches apart. Plant at the depth it grew in the nursery pot.
  3. Water sparingly once established. Rich soil makes the flavor milder, so skip the fertilizer.
  4. Harvest: Cut stems just before flowering, when flavor peaks. Dry bunches upside down in a shady, airy spot.

Varieties that do well here

  • Greek oregano (strongest flavor)
  • Italian oregano
  • Golden oregano

Watch out for
