Yellow Bean Growing Season
While each variety of yellow bean may differ slightly in time to maturity and growing conditions, the following generally applies to all yellow bean varieties.
Yellow beans are a warm-weather vegetable and should be planted in the late spring, two weeks after the last frost. Yellow beans grow best when planted in areas that get an average of six to eight hours of direct sunlight a day. Your yellow bean seeds should be planted 1 inch deep and in rows spaced 4 to 8 inches apart. Yellow beans do best in soil with a pH of 6.0 to 6.8.
On average, it takes 55 days for pole beans to reach maturity, and you will know that they are ready to harvest when the plant has a 10” spread and is 15” to 20” tall. Your pole beans are ready to harvest when the pods are 5” to 6” and feel full.
