Cranberry beans are an easy to grow plant. Neither pole nor bush beans, the cranberry bean grows on a stalk, which can attain a height of up to 6 feet. Due to this great height, the cranberry bean needs to be staked and grows well planted in a large container, such as a half barrel or even a 1-gallon pot. Growing cranberry beans can also be planted against a traditional trellis support or a tepee-shaped support can be created, against which several plants can be grown. However you decide to grow and stake your cranberry beans, remember they prefer a warmer climate than most bean varieties and definitely dislike frost. Soil temperature for cranberry beans should be at least 60 degrees Fahrenheit or more. Select an area with well drained soil and a pH of 5.8 to 7.0 or amend the soil to reflect the requirements.
