Jumbo – Organic Bean Seed

Giant Italian-style green beans.
Jumbo has extra-long dark green pods with rich flavor. While the beans are normally picked at 6–7″, they are still stringless at over 10″. Seeds are light brown with dark brown stripes. In very fertile soil, plants may grow short vines (runners), but need no support. Jumbo tends to have a lower than average germination rate. High resistance to bean mosaic virus. Organically grown. Avg. 800 seeds/lb. Packet: 35 seeds.

SCIENTIFIC NAME: Phaseolus vulgaris
CULTURE: Choose well-drained soil with a pH range of 6.5–6.8. After last frost date sow seeds about 2″ apart, 1″ deep, in rows 20–36″ apart. Optimum soil temperature for germination is 70–90°F (21–32°C). Plant when daytime soil temperatures average at least 60°F (16°C), or risk poor germination. Inoculants can increase yields. For a continuous supply, make successive sowings every 2-3 weeks through midsummer. Dark-colored seeds germinate better in cool soil than white seeds.
DISEASES: Plow under or remove and compost bean straw in the fall to hasten destruction of most disease organisms. For Sclerotinia spp. (white mold) control, plant at wider row spacing to promote drying of plant leaves and soil. Practice a 3-year crop rotation, preferably into corn or grain crops. All our bush bean seeds are produced in areas known to be free of halo blight.
INSECT PESTS: Mexican bean beetles can be controlled with insecticides such as pyrethrin or azadarachtin.
HARVEST: Regularly to encourage new pod set.
STORAGE: Store at 40°F (5°C) and 90% relative humidity for 7–10 days.
AVG. SEEDING RATE: 1M/125′, 1 lb./175′, 116M/acre at 8 seeds/ft. and 3′ row spacing.
SEED SPECS: See individual varieties.
