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.

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.

One of my favourite out-of-the-train-window memories is of a
greenhouse with nothing at all in it except a man sitting in an
armchair, reading a newspaper.

I have a reserved space in the polytunnel for that very purpose!
