Lima Bean Growing Season
While each variety of lima bean may differ slightly in time to maturity and growing conditions, the following generally applies to all lima bean varieties.
Lima beans are a warm-weather vegetable and should be planted in late spring, two weeks after the last frost. Lima beans grow best when planted in areas that get an average of six to eight hours of direct sunlight a day. Your lima bean seeds should be planted about 1 inch deep, and around 4 to 6 inches apart and in rows spaced 2 to 3 feet apart. Lima beans do best in soil with a pH between 6.0 and 6.8.
On average, it takes 65 days for lima beans to reach maturity, and you will know that the beans are ready to harvest when the plant has a 10” spread and is 15” to 20” tall. Your lima beans are ready to harvest when the pods are 4” and feel full.
Raw lima beans and roots are toxic to humans and animals! Always make sure to fully wash and cook lima beans before consuming them and keep out of reach of children and animals.
