when to plant green beans in iowa

The best time to plant green beans in Iowa is after the danger of frost has passed, typically around May 10 in central Iowa. Beans should be planted 1 to 1½ inches deep. For continuous harvest, bush beans can be planted every 2 to 3 weeks until about August 1, which is the last practical date for planting snap beans in Iowa. Pole beans can similarly be planted around this timeframe but require support for their vines. This timing ensures the soil is warm enough for optimal growth and reduces the risk of frost damage to the plants.
