Plant young oregano plants in Eugene Mar 15 – May 10.

Easy Plant young plants

Why these dates

Eugene's typical last spring frost is April 11. As a cool-season crop that handles light frost, this crop doesn't need to wait for that date. In the west-side valleys, though, the soil usually isn't ready to work until about March 15.

West-side valleys. The Willamette Valley, Puget Sound and southern Oregon valleys. Long frost-free seasons, but soil stays cold and wet into May, so warm crops wait for warm soil, not just the last frost.

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 Mar 15 – May 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

Few pests. Plants sprawl and get woody; cut them back by half in early summer.

A hardy perennial that thrives on neglect. Flavor is strongest just before it flowers.
