Runner Beans not setting
Runner beans do not grow very well in the far north of scotland so this
year I decided to try growing them in the polytunnel. The plants are growing very well, in fact I'm not sure whether I should pinch out the tops to stop them over-growing. My main problem is that the flowers are not setting any beans. How do I ensure pollination? Thanks in advance, Compo in Caithness. |

Possibly. A more common cause is too little water or too dry an atmosphere. They like reasonably high humidity and plenty of water at the roots (but not waterlogging). A lot of the older gardeners spray their Runners with water every evening, and swear it helps setting. -- Regards Bob in Runnymede, 17miles west of London, UK ******** Yup!. Spraying the flowers in enclosed situations has always been a typical ploy for pollination. Well-known to tomato growers. My Dad used to gently hand-wiggle the tomato canes , ( to shake the pollen about, he used to say.) once a day in the morning or evening, or tap them with a small stick or cane. I always do that. Does it do any good?. Dunno!, but except for disasters like when I was on holiday). , a neighbour who used weedkiller by mistake and most others who forget to turn up to water them on a belting hot day I find I am feeding fruit to the multitudinous relatives who have gardens with the grass higher than the windowsills. Nemmind, -Eh!, - in the past those two warm, mind-calming greenhouses have been a refuge in times of great stress. Doug. ******* |
