Fresh Shell Beans - Key Growing Information

Freshly harvested fresh shell beans in the field, enough to make a whole meal.

SCIENTIFIC NAME:

Phaseolus vulgaris

CULTURE:

Choose well-drained soil with a pH above 6.0. After the last frost, sow directly in the garden 1" deep and about 2" apart, in rows 20–36" apart. Beans germinate best in soil at 70–90°F (21–32°C); wait until daytime soil temperatures average 60°F (16°C) or more, or germination may be poor. Inoculants often boost yields. Sow again every 2–3 weeks until midsummer for a steady supply. Don't thin. Dark-seeded varieties germinate better in cool soil than white-seeded ones.

DISEASES:

In fall, turn under or pull and compost the spent plants so most disease organisms break down faster. To limit white mold (Sclerotinia), give rows extra width so leaves and soil dry quickly. Rotate on a 3-year cycle, ideally following with corn or small grains, and start with clean, high-quality seed to help keep halo blight out.

INSECT PESTS:

For Mexican bean beetles, use insecticides such as pyrethrin or azadirachtin.

HARVEST:

Picking regularly keeps plants setting pods. Harvest once the beans inside are plump.

STORAGE:

Keeps 7–10 days at 40°F (5°C) and 90% relative humidity.

SEEDING RATE:

Italian types: 1 lb. sows about 150', 10 lb. about 1,000'; about 145 lb. per acre at 3' between rows. French types: 1 lb. sows about 300', 5 lb. about 1,000'; about 72 lb. per acre.

SEED SPECS:

Average seeds per lb.: Italian about 850; French about 2,200.

PACKET:

Italian and French: 100 seeds per packet, enough for about 14'.
