How easy is it to grow your own?

Runner beans are easy to grow from spring to autumn, but they’re not frost-hardy. They need a fertile, deep bed with organic matter or large container of rich potting compost in a sheltered spot. Sow outdoors once the soil reaches 12C or start in pots indoors. Provide a tall wigwam for everything other than dwarf varieties, as the plants may reach 3m. Water as soon as flower buds appear.
