How to grow pole bean

Phaseolus vulgaris · Fabaceae · Vegetable

Pole Bean is a warm-season vegetable in the Fabaceae family, almost always sown straight into the ground where it will grow. It wants full sun (six or more hours of direct light) and steady, even moisture. From sowing to first pick is about 60–70 days. It is killed by frost, so nothing goes outside until the danger has passed and the soil has warmed.

Grower’s note: One well-tended sowing keeps producing for 6-8 weeks if you pick often. Set the trellis at sowing time.

Sowing

Sow about 1.5″ deep, into soil between 60–90°F — germination is quickest near 80°F. Germination takes a week or two (6–10 days). It does not transplant well, so sow it in its final position rather than starting it in pots.

Spacing & layout

Give each plant about 6″ along the row with roughly 42″ between rows. On a square-foot grid that is 8 per square foot. Allow at least 18″ of loose, workable soil for the roots. It grows well in containers at least 12″ deep.

Fitting it to your season

Pole Bean needs roughly 60–70 frost-free days to crop. Where the season is shorter than that, start it indoors and choose the earliest-maturing varieties, or grow it in a container you can move under cover on cold nights. In long, hot-summer regions it can often be planted twice — once in spring and again in mid-to-late summer for a fall harvest.
