When the soil is warm, space pole beans 4 to 6 inches apart. The rows of beans should be 30 to 36 inches apart from each other.
Bush beans are compact and require 2 to 4 inches between each plant. When you plant the bush beans, space the rows 18 to 24 inches apart. Thin the seedlings so the plants are at least 2 inches apart from each other.
You can have fresh beans all season long by spacing the first planting of bush beans further apart and, in two weeks, sow another planting of beans between the first. You can continue to reseed the garden every two weeks until six weeks before the first hard frost.
