Beans are a warm season crop, tender to light frosts and freezes. Bush beans are usually determinate, with one clean harvest, so plant every 10 days for a continuous harvest. Beans can be grown in average soil, almost anywhere in the United States. They grow best if the soil is well drained and the summer is consistently warm. Seeds will rot in the ground in cold, damp weather. Since Beans are subject to downy mildew, they should not be grown where there are cold summer fogs.
