Easy Plant seeds in the ground

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 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. Prepare the bed: loosen the soil and mix in an inch or two of compost.
  2. Plant seeds Mar 1 – Apr 5, 1 to 2 inches deep, 6 inches apart.
  3. Keep the soil evenly moist until sprouts appear, which can take one to three weeks in cool soil.
  4. Harvest: Pick pods when they bulge with beans but are still green. Shell the beans and slip off the pale skins for the sweetest flavor.

Varieties that do well here

  • Broad Windsor
  • Aquadulce Claudia (for fall sowing)
  • Vroma

Watch out for

Black aphids gather on the growing tips in late spring. Pinch off the tips once pods start forming.

Unlike other beans, favas love cool weather. West of the Cascades they can also be sown in October to overwinter for an early crop.
