CULTURE: Choose well-drained soil with a pH above 6.0. 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 untreated seed 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 mid-summer. 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 white mold control, plant at wider row spacing to promote drying of plant leaves and soil. Practice a three-year crop rotation, preferably into corn or grain crops. All our bush bean seeds are Halo-Blight free.
INSECT PESTS: Mexican bean beetles can be controlled with pyrethrin or azadirachtin. (See Index)
HARVEST: Regularly to encourage new pod set.
