Easy Plant young plants

Why these dates

Wenatchee's typical last spring frost is April 8. As a cool-season crop that handles light frost, this crop doesn't need to wait for that date. In the Columbia Basin and low eastern valleys, though, the soil usually isn't ready to work until about April 1.

Columbia Basin and low eastern valleys. Hot, dry summers and quick spring warm-up. Warm crops go in earlier than west of the Cascades, and irrigation matters more than rain.

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 thyme plants Apr 1 – May 27, 12 inches apart. Plant at the depth it grew in the nursery pot.
  3. Water only until established; thyme prefers dry soil. Replace plants every few years when they get woody.
  4. Harvest: Snip sprigs before the plant flowers for the best flavor. Trim lightly after flowering to keep it compact.

Varieties that do well here

  • English thyme
  • French thyme
  • Lemon thyme

Watch out for

Root rot in heavy, wet soil. Give it gravelly soil or a raised spot.

Drought-tolerant once established and hates wet feet. Raised beds and rocky edges suit it.
