When to plant pole beans in Oregon and Washington

In Portland: Plant pole beans from seed, directly in the garden, May 10 – Jun 14. In Bend: Jun 16 – Jul 21. Find your city below.

Climb 6 to 8 feet and keep producing for weeks. Put up the trellis before you sow. Like bush beans, they need warm soil.

Prepare the bed: loosen the soil and mix in an inch or two of compost.
Plant seeds on your city's dates, 1 inch deep, 4 to 6 inches apart along a trellis.
Keep the soil evenly moist until sprouts appear, which can take one to three weeks in cool soil.
Harvest: Pick when pods are pencil-thick and before the seeds bulge. Picking every few days keeps the vines producing.

Seeds rot in cold, wet soil, the most common Northwest bean failure. Wait for warm soil.
