I live far north of Scotland and grow my runner beans in my greenhouse. They are growing extremely strong and have lots of flowers, however, a lot of the flowers are falling off and no beans have appeared? Any reasons for this please?

Some one else asked this question a few days ago and I think the general concensus was that Runners don't do HEAT very well and that the hot weather was stopping the flowers from setting. Possibly your greenhouse is a little too hot at the moment and the result is the same.
Misting the flowers at the end of the day was one suggestion (I think) to cool the flowers down and aid setting. If it makes you feel any better my runners are suffering as well.

They may also not be getting the insects they need to fertilise the flowers.
Some of us live in the past, always talking about back then. Some of us live in the future, always planning what we are going to do. And, then there are those, who neither look behind or ahead, but just enjoy the moment of right now.
Which one are you and is it how you want to be?Comment

Runner beans
Yes I had that problem. I mist them at night. Not so many flowers falling now.
Good luck with them. It seems to be trial and error with it all.Comment

Same problem here too. Not one bean so far

It could be either the heat (as others have said) or lack of pollination. Runner beans don't self pollinate... If they did I'd be soooo happy! I love runner beans and would grow them in my living room

The point of misting is to open a wilted (from heat) flower, so that bees may enter. However, it is an old wives tale ... so save your timeOriginally posted by evie b View PostAll gardeners know better than other gardeners." -- Chinese Proverb.Comment

I usually find that the first flowers fall off, but it's always worked out alright eventually! In a few weeks time you'll probably be wondering what to do with all the beans!Life is too short for drama & petty things!
So laugh insanely, love truly and forgive quickly!Comment

So there is still hope then? Thats good to hear.Comment

Give them a potassium rich feed to encourage flowering and I always give mine a weak feed of Epsom salts to help with magnesium intake."We can complain because rose bushes have thorns, or rejoice because thorn bushes have roses."-- Abraham LincolnComment

I have little black dots over my beans. Any idea what they are and how to get rid of them. This is my first year of growing beans and need any help I can get.Comment

Those could well be blackfly, Jalnald - in which case a bit of judicious squishing between finger and thumb would not go amiss. I'm having a bad year for blackfly myself!!Whooops - now what are the dogs getting up to?Comment

I was wondering the same thing as I've had loads of flowers but then nothing. I checked them over earlier this evening and lo behold I found a bean! YAY!
Black and white fly seem to have hit this part of Kent quite bad this year.Comment
