Why these dates

Seattle and Tacoma's typical last spring frost is March 2. In the west-side valleys, the soil is usually ready for strawberries around 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 strawberry plants Mar 15 – Apr 26, 12 to 18 inches apart. Crown at soil level: not buried, roots covered.
  3. Water regularly, mulch with straw, and pinch off runners in the first year so plants put energy into roots.
  4. Harvest: Pick fully red berries every couple of days, in the morning, with the cap attached.

Varieties that do well here

  • Hood (an Oregon classic)
  • Shuksan
  • Seascape (everbearing)
  • Albion (day-neutral)

Watch out for

Gray mold (botrytis) in wet springs and slugs on ripe berries. Mulch with straw to keep fruit off the soil.

June-bearers give one big crop; everbearers and day-neutrals give smaller harvests through summer. Oregon and Washington breeding programs have produced many of the best varieties for this climate.
