Plant Romano bean seeds in the spring once the soil warms and all danger of frost has passed in your area. Beans require a soil temperature of at least 60 degree Fahrenheit to germinate with optimal germination occurring at 80 F.
Sow seeds to a depth of 1 inch spaced 2 to 3 inches apart. Cover the seeds and firm the soil down with your hands or the back of the hoe securing the seeds and removing air pockets. Allow 2 to 3 feet between rows for ease of cultivation.
Thoroughly moisten the soil with water to a depth of 2 to 3 inches. Keep the soil evenly moist until seeds germinate in seven to 10 days. Germination time depends on soil temperatures and the cultivar grown.
Reduce watering to once or twice a week, or whenever the soil feels dry 1 inch below the surface. Deep watering moistening the root zone is preferred, as frequent, light watering encourages roots to form near the soil’s surface.
Remove weeds as soon as they appear by hand picking or cutting them at the ground level with a sharp hoe. Weeds rob your bean plants of both water and nutrients, and may introduce disease.
Harvest Romano beans for eating fresh when they are young and tender before the beans reach full size. For dried beans, allow the pods to mature on the vine before harvesting and drying.
