How many pole bean plants can I put in a container? I am just starting my container garden for the second year. I am growing pole beans this year, Kentucky Blue. I have 3 containers that measure 24 in circumference x 17.5 height. How many pole bean plants can I put in each container? My plan is 4, evenly spaced. I am using Miracle fortified garden soil mixed with cow manure and compost. Can I plant more?
