Broad bean conundrum

[Pete C]

I have several broad beans (Aquadulce Claudia) which were started indoors in February. They were then hardened off and eventually planted out in late March. They've done well so far, growing strongly, until a few days ago.

Leaves in the middle of the main stem have yellowed, with some dropping off. The leaves at the top of the stem are still bright green, as are the leaves on new shoots coming from the base of the plant.

I've read about nitrogen deficiency, but wonder whether that would just affect some laves.

Any clues?

Am wondering if they've been overwatered?
Other than that have no clue sorry!
Hope they survive, I love broad beans.

This may be normal, my beans have yellow leaves that have suffered the onslaught of some very cold spells, but they are growing tall and flowering now.. As long as the new stuff looks good then I think you should be fine. You could sprinkle some chicken manure pellets around to help them along.

Hmmm....not sure what could cause that, probably cold weather as suggested. I've got the situation that I have salvaged 4 little plants from overwintering that are planted in the garden, are in full flower, but we have no bees/hoverflies yet to help polinate them, so the flowers are just dying off I saw one hoverfly 2 days ago at the end of the garden, so there may be hope yet.
