According to the University of Illinois, beans are the second most popular vegetable to plant in gardens, next to the tomato. Beans come in two varieties--bush and pole. Bush beans grow on a bush and are easier to maintain, while pole beans need some kind of support to grow on.
Where to Plant
Beans need full sun in which to thrive; this means six to eight hours of sunlight a day. They also need well-drained, rich soil, according to the University of Purdue. Work some compost or manure into your soil before you plant your beans to improve your soil. Space bush beans 4 inches apart in rows 1 to 2 feet apart. Space pole beans 6 inches apart in rows 3 feet apart.
When to Plant
Beans are warm season vegetables so they do not handle cold well. Plant them after the last frost date has passed by about a week to ensure it is warm enough. New bean plants can be set out every two weeks to increase the harvest of beans you have all summer.
Water beans once a week, adding an inch of water each time. If your climate is naturally wet you may not have to water beans at all except during dry spells. Water plants early in the morning for the best growth. Cut down any weeds growing around the beans with a hoe. Do not pull the weeds out of the ground, as you may disturb the bean's roots while you do it, since beans have shallow roots.
Pick your beans when the pods are fully grown and firm. Be sure to pick them when the plant is dry, as picking from wet bean plants can increase the risk of disease in the plants.
