Have your soil tested. Beans grow best in slightly acidic to neutral soil, pH between 6 and 7. Clay or silt loams are better for bean production than sandy soils, although good drainage is important. Use well-rotted manure or compost at planting to increase soil organic matter.
While you can speed germination of many seeds by soaking in water overnight, don’t soak beans before planting. Bean seeds lack the hard outer shells that need pretreatment to speed sprouting.
On average, it takes bean plants a little less than two months to produce beans and fully mature, but different cultivars have different maturities. The time can vary from 45 to 75 days, depending on the cultivar and the climate.
