Beans need as much sunlight as possible. Choose a location that offers full sun exposure for the better part of the day. If you start your plants indoors, keep them near a window or other light source.
Beans grow best in fertile soil that is moist and well drained with a neutral to slightly acidic pH. They are a warm-season crop, and do best when all danger of frost has passed. Rotate your crops so that you don't plant beans in the same location year after year.
Plant beans -- particularly pole beans -- at the north end of your garden so that they receive sunlight without blocking other plants from the sun. Bean plants grow tall and can cast a heavy shadow.
