Mine have done the same - gorgeous healthy young plants from seed in my greenhouse and they've gone yellow in the allotment. Same has happened to my runner beans. I am beginning to suspect the soil quality. Beans seem to like easily draining soil and also I have been adding some nitrogen and see if it helps - lack of nitrogen can cause the yellowing too. Good luck with yours.
Too cold?
I'd say that it's low temperatures - Brrrrrr!!!
Most French beans prefer warmer tempertures than we've got at the moment.
In future you might like to try Buerre de Rocquencourt dwarf bean (a lovely yellow wax bean type with a great flavour) which is more tolerant of cooler springs.
Gardening in Central Norfolk on improved gritty moraine over chalk ... free-draining.
yeah mine have done the same, didn't stop the little slugs though.
They could have been planted out too early as its been so cold, Try feeding them phosphorgen they should recover.
This has happened to a lot of different plants around my garden - hebes, herbs etc. I have assumed the changes in temperature as these plants like warm climates and it has been ridiculously cold at times for the time of year.
And they were in a greenhouse when it happened, so they were warm, here in London.
Not pleased...
Sometimes they look promising for weeks, do produce, but sooner or later the yellowing happens. They are planted out in succession, so it seems odd it would be weather variation, as they do not all experience the same weather changes outside. I've always assumed the soil here doesn't really suit them, though I doubt there is just one cause for it.
I noticed that the more sunshine after cool nights seems to accelerate it, but it never happens before July so I think it's age + temperature related. Doesn't affect the plants though, they just throw out new tendrils and I take off the yellowing leaves before they mould over.
