Today the runner bean is one of our best loved & widely grown vegetables. It is known as an oriental climber in most countries. Its other popular names are scarlet bean, & Dutch case knife bean. It has been grown for over 2,000 years originating in the tropical uplands of Central America. Runner beans grow best in a warm spot which also encourages pollinating insects. Do not grow them in the same position every year , as this is likely to build up root rotting diseases.
They enjoy a rich drained soil, & a sheltered sunny position. Beans will wrap round your canes anticlockwise & when they reach the top of your cane supports, its a good idea to cut the plant off at the top to encourage the plant to bush out then you will get more beans. Water plants liberally & frequently especially during dry spells. Tie young plants loosely to the canes & protect them from slugs, they will quickly climb naturally & will need no other support.
