When to plant raspberries in Portland, OR

Plant raspberry canes in Portland Mar 15 – Apr 26.

Moderate Plant bare-root canes

Why these dates

Portland's typical last spring frost is March 13. In the west-side valleys, the soil is usually ready for raspberries 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 raspberry canes Mar 15 – Apr 26, 2 to 3 feet apart in rows. Roots covered by 2 to 3 inches of soil.
  3. Set up a simple trellis with posts and wire. After harvest, cut spent canes to the ground.
  4. Harvest: Pick when berries slip easily off the core. Check every two or three days in season.

  • Meeker (a Northwest favorite)
  • Tulameen

Watch out for

Root rot in soggy soil. Plant in a raised row or a bed that drains well.

Need well-drained soil; they die in soggy ground. A raised row helps in wet Northwest winters. West of the Cascades, fall planting works well too.
