When to plant rhubarb in Everett, WA

Plant rhubarb crowns in Everett Mar 1 – Apr 12.

Easy Plant dormant crowns

Why these dates

Everett's typical last spring frost is March 9. As a hardy perennial, 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 1.

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 rhubarb crowns Mar 1 – Apr 12, 3 to 4 feet apart. Crown buds 1 to 2 inches below the surface.
  3. Mulch with compost each spring, and cut off flower stalks as soon as they appear.
  4. Harvest: Pull (don't cut) stalks when they're 10 to 15 inches long. Take no more than a third at once, and stop in early summer. Never eat the leaves.

Varieties that do well here

  • Victoria
  • Canada Red
  • Crimson Red

Watch out for

Crown rot in soggy soil. In wet west-side gardens, plant on a slight mound or in a raised bed.

Plant it where it can stay for a decade. Don't pick the first year, and never eat the leaves, which are poisonous.
