Pole Beans. Pole beans grow to heights of 10 feet or more and require staking. Many prefer the increased size and rich flavor of pole beans to that of bush beans. However, they require more time to reach maturity. Pole beans, such as Kentucky Wonder and Kentucky Blue, produce tender green pods that mature in 65 to 75 days. Half-runner beans, such as Mountaineer and Mountaineer White, reach a height of approximately 3 feet and benefit from trellising. These green beans are a cross between bush beans and pole beans.
Bean plants need about an inch of water per week. The beans should be watered in the morning so the foliage is dry before dark. Bush beans will mature in 50 to 60 days; pole beans in 60 to 90 days. Beans are light feeders and do not need extra fertilizing as long as you plant in an enriched soil.
