Runner beans looking anaemic

It's quite likely that they have been frosted, have they had any protection? They are not supposed to be planted out till risk of frost is over
Mine got frosted last year and died so don't know if yours will recover.

Perhaps you need to resow see if anybody thinks otherwise........

Not convinced it is frost damage, the reason for my argument is we here in the tropics of Lancashire have not had external temps below 8 degrees, also Old Bob, has had his beans out for a few days now in his cold frame without the lid on, and his are a deep green colour, same variety as mine which went pale yellow over the weekend, there is a lot of grumbling at the mo about the composts being used, chaps are having problems this year big time with failings after potting on. I have given mine a soaking in seaweed extract and this morning they did look a little better. I mentioned in another post that I was having problems after potting on where the plants would keel over and we all on our site suspect some very dodgy compost which we mentioned to our LGC who told us they do have a high turn over and it hasn't been lying around. Our site rep is making enquires with other sites to see what is being used and if they to are having problems.

I'm not that far away from you SoyaBean and we had a frost here last week.  Lots of people got caught who had planted things out early, even some had spuds that were badly frosted.

If the yellowing is a nutrient problem, feeding should see a pretty instant result.

I've got three runner beans that self seeded, and I've left them where they are for the minute.  I did think at the weekend though that they looked rather pale.  Whatever the cause you've plenty of time to resow.

If you haven't got any seeds left, please let me know I've got oodles and can pop some in the post to you.

Thanks, everyone, for your comments.  I think that because I was so early they got a chill.  Doing all right now and I'll be the first with beans 'cos they are now in flower.
